Active strategy in relation to algorithmic trading refers to a type of investment or trading approach that uses algorithms to make regular, data-driven decisions about buying and selling assets. This approach is designed to generate higher returns and outperform passive investment strategies.

Active strategies in algorithmic trading differ from passive strategies, which simply follow the market and hold assets for the long-term, in that they actively seek to generate higher returns through regular buying and selling of assets. This can involve taking advantage of short-term market movements, or making trades based on a variety of market indicators and economic data.

An alpha model is a mathematical or quantitative framework used to generate trading signals that can be used in portfolio construction.

The alpha model seeks to identify assets that are likely to outperform or underperform their peers, based on a variety of factors and variables.

Alpha models can be constructed using a variety of techniques, such as statistical analysis, machine learning algorithms, or financial modeling. The inputs to an alpha model may include company financial statements, price and volume data, macroeconomic indicators, and other market data.

Once an alpha model generates trading signals, the portfolio manager can use those signals to construct a portfolio that aims to generate alpha (i.e., excess returns) relative to a benchmark index. The portfolio manager may use other tools, such as risk management techniques or diversification strategies, to manage portfolio risk and optimize performance.

It is important to note that alpha models are not foolproof and can be subject to various biases and errors. As such, portfolio managers must continually test and refine their alpha models to ensure that they are producing accurate and robust trading signals.

In a market with low volatility, the Bollinger Bands will be closer together, while in a market with high volatility, the bands will be further apart. When prices move outside the upper band, it can be a sign that the security is overbought, and a potential selling opportunity, while a move below the lower band can indicate that the security is oversold and a potential buying opportunity.

In quantitative finance, carried interest refers to a share of profits or investment gains that are allocated to investment managers or general partners in certain types of investment funds, particularly private equity funds, venture capital funds, and sometimes hedge funds. It represents a portion of the fund’s profits that the manager or general partner is entitled to receive as compensation.

Carried interest is typically structured as a profit-sharing arrangement. It is distributed to the investment manager or general partner after the fund’s investors, also known as limited partners, have received a predetermined return on their investments, often referred to as the hurdle rate or preferred return. The manager or general partner receives a share of any profits above this hurdle rate, usually a percentage ranging from 10% to 30%.

The term “carried interest” derives from the concept that the investment manager or general partner carries an interest in the fund’s profits, in addition to their capital investment. The carried interest serves as an incentive for the manager to maximize the fund’s performance and generate strong investment returns, as their compensation is directly tied to the success of the investments.

Because carried interest is not exited or liquidated, it is more tax efficient there are no capital gains for holding.

In quantitative finance, compounding returns refer to the process of reinvesting profits or earnings generated from an investment back into the investment itself. It involves earning returns not only on the initial investment but also on the accumulated earnings from previous periods.

When returns are compounded, they have the potential to grow exponentially over time, thanks to the compounding effect. The compounding effect arises from reinvesting the returns, allowing them to generate additional returns in subsequent periods. As the investment grows, the compounding effect becomes more significant, leading to accelerated growth over the long term.

To illustrate the concept, consider an investment with an annual return of 10%. If the returns are compounded annually, the initial investment will grow by 10% each year. However, if the returns are compounded more frequently, such as quarterly or monthly, the growth rate will be higher due to the reinvestment of earnings more frequently. This compounding effect can be especially powerful when investing over long periods.

The compounding effect is commonly observed in various investment vehicles, such as stocks, bonds, mutual funds, and other financial instruments. It is an essential concept in quantitative finance as it influences the calculation of investment performance, risk assessments, and the determination of investment strategies.

When analyzing investment performance or projecting future returns, it is crucial to consider the impact of compounding. Investors often use compound interest formulas or specialized software to calculate and project the compounded returns based on the investment’s expected growth rate and compounding frequency.

The process involves splitting the dataset into two subsets: a training set and a test set. The model is trained on the training set and then evaluated on the test set. The results are compared to determine how well the model performs on new data.

In quantitative finance, “crystallisation” typically refers to the process by which the value of a fund investment is determined or realized. It involves calculating the net asset value (NAV) of the fund and providing investors with a clear picture of their investment’s worth.

Crystallisation in funds occurs at specific intervals, such as daily, weekly, monthly, or quarterly, depending on the fund’s valuation frequency. At these intervals, the fund’s assets are evaluated, and the NAV per share or unit is calculated. The NAV represents the total value of the fund’s assets minus its liabilities, divided by the number of outstanding shares or units.

Investors use the crystallized NAV to assess the value and performance of their fund investments. It allows them to understand the current worth of their holdings and make informed decisions regarding buying, selling, or redeeming fund shares.

Crystallisation is particularly significant in open-end mutual funds and exchange-traded funds (ETFs) where shares can be bought or sold on a regular basis. It provides transparency and liquidity to investors by ensuring that the value of their investments is regularly determined and accessible.

It’s important to note that crystallisation in funds does not refer to the same process as crystallisation in investments, where it signifies the realization of gains or losses. Instead, in the fund context, it pertains to the determination of the fund’s value for the benefit of investors.

Dollar cost averaging (DCA) is an investment strategy in which an investor divides a larger sum of money into smaller investments, made at regular intervals over a longer period of time. The goal of dollar cost averaging is to reduce the impact of market volatility on the investment portfolio by spreading out the investment over time, rather than investing the entire amount at once.

For example, an investor who wants to invest $10,000 in a stock may choose to invest $1,000 every month for 10 months, rather than investing the full $10,000 in one lump sum.

This approach can help to reduce the impact of short-term market fluctuations and allow the investor to accumulate more shares when prices are low and fewer shares when prices are high.

ERC-20 is the original token standard for Ethereum.

ERC-20 is a technical standard used to issue and implement tokens on the Ethereum blockchain.\nIt was proposed in November 2015 by Ethereum developer Fabian Vogelsteller and defines a common set of rules such as how the tokens can be transferred, how transactions are approved, and the total supply of tokens. ERC-20 tokens are the most commonly used tokens on the Ethereum network and are designed to be used for paying for functions.

ERC-20 token standard has several limitations and architectural shortcomings.\nIts approve() and permit() based functions, originally planned for having\nbetter smart contract security in Solidity, have proven to be an attractive\nvector for scams as normal users do not understand they are transferring tokens\nwhen calling these methods from their wallets.

In data research and analysis, “forward fill” refers to a method of handling missing or incomplete data by carrying forward the last observed value to fill in the gaps. It is also known as “last observation carried forward” (LOCF).

When dealing with time series data or datasets with missing values, forward fill involves replacing missing data points with the most recent known value. This approach assumes that the value remains constant until a new observation is available. By using the previous observation as a substitute, forward fill helps maintain continuity in the data and allows for continued analysis or modeling.

Forward fill is often employed when missing data is considered to be missing at random (MAR), meaning the missingness is not related to the actual value. It can be a useful technique when the missing data points are intermittent or occur sporadically.

However, it is important to note that forward fill may not always be appropriate or suitable for all datasets or analysis scenarios. It assumes that the missing values should be carried forward, which may not be accurate or appropriate in all cases. Researchers should carefully consider the nature of the data and the implications of using forward fill before applying it.

Alternative methods for handling missing data include backward fill (carrying the next observed value backward) or more sophisticated imputation techniques that estimate missing values based on statistical methods or predictive models. The choice of method depends on the specific characteristics of the dataset and the objectives of the analysis.

Machine learning algorithms are used in a wide variety of applications, including email filtering, speech recognition, and computer vision. They are also used in finance, where they are used to predict stock prices, detect fraud, and make trading decisions.

Machine learning algorithms can be classified into two broad categories: supervised learning and unsupervised learning. Supervised learning algorithms are trained using labeled data, while unsupervised learning algorithms are trained using unlabeled data.

Supervised learning algorithms are used to solve classification and regression problems. Classification problems involve predicting a discrete class label, while regression problems involve predicting a continuous quantity.

A management fee is a recurring fee charged by investment managers or fund managers for managing and overseeing investment portfolios or funds on behalf of investors. It is a compensation mechanism for the services provided by the manager in managing the assets and making investment decisions.

The management fee is typically calculated as a percentage of the total assets under management (AUM). The percentage fee can vary depending on the type of fund, investment strategy, or asset class. It is usually expressed as an annual rate and is deducted from the fund’s assets on a regular basis, such as quarterly or annually.

The management fee covers various costs associated with managing the fund, including research, analysis, portfolio construction, trading, administrative expenses, regulatory compliance, and compensation for the investment manager’s team. It is meant to compensate the manager for their time, expertise, and resources devoted to managing the investments and ensuring the fund’s operation.

Management fees are disclosed in the fund’s prospectus or investment management agreement, providing transparency to investors regarding the costs associated with their investment. The fee structure is an important consideration for investors when evaluating investment options, as it directly affects the net return they will receive.

It’s worth noting that management fees are separate from other fees that may be associated with investment funds, such as transaction fees, custodial fees, performance fees (in certain funds), or expense ratios (in mutual funds and ETFs). These additional fees cover specific services or costs beyond the general management of the fund.

In quantitative finance, maximum drawdown (MDD) refers to the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. It is a measure of the largest loss that an investment portfolio has experienced over a specified time period.

Maximum drawdown is an important metric in risk management as it helps investors understand the potential downside risk of an investment. It is often used to assess the risk of a portfolio and to compare different investment strategies.

For example, suppose an investment portfolio has a maximum drawdown of 20%. This means that the portfolio has experienced a loss of 20% from its peak value before a new peak is reached. In other words, the portfolio has lost 20% of its value at some point in the past.

Maximum drawdown is typically expressed as a percentage of the portfolio’s value. It can be calculated using the following formula:

\n\\[MDD = \\frac{P - T}{P}\\]

where P is the peak value of the portfolio and T is the trough value.

As a rule of thumb, the maximum drawdown should not be more than 1/3 of the strategy annual returns. For example, if a strategy has an annual return of 30%, the maximum drawdown should not exceed 10%.

Malicious Extractable Value (MEV) is a measure of the profit a blockchain block producer can make through their ability to arbitrarily include, exclude, or re-order transactions during the block production process. It refers to the maximum amount of value that can be extracted from block production in excess of the standard block reward and gas fees.

MEV is also known as Miner Extractable Value (original proof-of-work term) and Maximum Extractable Value.

Because of block producers’ ability to reorder trades in a single leader blockchain consensus\nmodel, MEV causes negative slippage and other issues for traders.

Market participants in the position to do MEV can harm traders in multiple ways:

MEV operators frontrun trades and liquidity changes to get a better price for themselves as they see the market is about to change. This is often a tactic used in CEX-DEX\narbitrage. More on CEX-DEX arbitrage here.
MEV operators perform sandwitch attack to manipulation the market, by frontrunning and backrunning the trade to set the price to some arbitrary value.
Backrun the the trades to extract any arbitrage opportunities that are opened by executing the trade.

Most of MEV is a harmful for traders and protocols as it extracts value out from the system and moves it to a third party, unrelated to the actual trading activity. If traders\ncould choose, they would always choose a system without harmful MEV instead of a system with it.\nFurthermore, frontrunning and market manipulation are illegal in many jurisdictions. Backrunning is generally found acceptable,\nespecially if it distributes some of arbitrage profits back to traders and protocols.

Getting rid of MEV is often referred as “solving MEV” or “minimising MEV.”

MEV can be prevented by\n- Using private pools. Most popular solutions include changing our EVM JSON-RPC node to one that supports

\n
a private mempool, like MEV Blocker. However these systems are trust-based so they are not ideal,\nas the private mempool operator itself could extract value, though this could be quite easily audited afterwards.
\n

Making transactions invisible to block producers. This is called to a shutter or shielding. One way to achieve this\nis to use two-phase commit and reveal scheme, also known as commitment scheme for including transactions in a block.\nShutter Network is a commit-and-reveal scheme for EVM block building.
Backrunning built into the protocol itself to capture any arbitrage left after routing a trade. Osmosis is doing this\nif the form of ProtoRev module. More about ProtoRev solution here.
Most EVM-compatible blockchains and virtual machines are not powerful enough to do backrunning on-chain, but off-chain solutions like CowSwap and MEV Blocker exist.
Creating a blockchain block production system where there is no single leader who can decide on transactions. See Advanced consensys system design presentation here.
CEX-DEX arbitrage, though not always MEV but harmful for decentralised finance ecosystem due to its harm for passive liquiditity providers, can be mitigated with dynamic fees, introduced by Uniswap version 4. More on dynamic fees mitigating arbitrage here.

The mid price, in the context of AMM, is the price that reflects the ratio of reserves in one or more pairs. There are three ways we can think about this price. Perhaps most simply, it defines the relative value of one token in terms of the other. It also represents the price at which you could theoretically trade an infinitesimal amount (ε) of one token for the other. Finally, it can be interpreted as the current market-clearing or fair value price of the assets.

In trading strategy, momentum refers to the rate of change in the price of a financial asset over a given period of time.

The price change si often expressed as a change in the open-close data. E.g. the price of an asset\nat the opening of the week vs. closing price as the end of the week.

Momentum traders seek to profit from short-term price trends by buying assets that have been performing well and selling those that have been performing poorly.

Momentum traders typically use technical analysis to identify assets that are exhibiting strong positive or negative momentum. They may look at indicators such as moving averages, relative strength index (RSI), and MACD (moving average convergence divergence) to determine the current trend and potential entry and exit points.

One common strategy used by momentum traders is to buy assets that have recently experienced a significant price increase, on the assumption that the upward trend will continue. This is known as a “breakout” strategy. Conversely, they may sell assets that have experienced a significant price decrease, on the assumption that the downward trend will continue.

It is important to note that momentum trading can be risky, as price trends can quickly reverse direction, leading to significant losses if a trader’s positions are not properly managed. It is therefore important for traders to have a well-defined strategy, strict risk management rules, and the discipline to stick to their plan even in the face of short-term fluctuations.

In decentralised finance, on-chain refers to transactions or activities that are recorded and processed directly on a blockchain network. It is the opposite of off-chain.

In a blockchain, transactions are verified by nodes in the network and added to the chain of blocks that make up the blockchain. These transactions are permanent and unalterable, and the state of the blockchain can be seen by anyone on the network.

When an activity is referred to as “on-chain,” it means that it is recorded directly on the blockchain, as opposed to off-chain, which refers to transactions or activities that are not recorded on the blockchain but are still facilitated by the network.

On-chain transactions are typically considered to be more secure and transparent than off-chain transactions, as they are recorded in a public ledger that is immutable and auditable. Additionally, on-chain transactions are often processed more quickly and with lower fees than off-chain transactions, as they do not require intermediaries or intermediating networks.

In quantitative finance, a performance fee is a form of compensation that investment managers or fund managers may receive based on the performance of an investment or a fund. It is typically an additional fee on top of the management fee and is structured to align the interests of the manager with the investors.

The performance fee is earned when the investment or fund achieves certain predefined performance benchmarks or exceeds a specified hurdle rate. The specific terms and conditions of the performance fee are outlined in the fund’s prospectus or investment management agreement.

The calculation of a performance fee can vary depending on the fund or investment strategy. Commonly, it is calculated as a percentage of the investment gains or profits generated by the fund. For example, if the fund’s performance fee is set at 20% and the fund achieves a return of 10%, the performance fee would be 20% of the 10% gain, resulting in a 2% fee. Fees are calculated for a specific crystallisation period.

Performance fees are intended to incentivize fund managers to deliver superior investment results. By linking compensation to investment performance, investors hope to encourage the manager to make strategic investment decisions that maximize returns. It aligns the manager’s interests with those of the investors, as the manager benefits from generating positive investment results.

It’s important to note that performance fees are more commonly associated with alternative investment vehicles such as hedge funds, private equity funds, or certain types of actively managed mutual funds.

Position sizing in quantitative finance refers to the process of determining the appropriate size or quantity of an investment position to take in a financial instrument, such as a stock or a derivative, based on a predefined set of rules or strategies. It is a crucial aspect of portfolio management and risk control.

The goal of position sizing is to allocate capital efficiently, taking into account factors such as risk tolerance, investment objectives, market conditions, and statistical analysis. The position size is typically determined by a combination of quantitative models, statistical techniques, and risk management principles.

Some commonly used approaches to position sizing include:

Fixed Fractional Position Sizing: This approach involves allocating a fixed percentage of the total capital to each trade or investment. For example, a strategy might allocate 2% of the total capital to each trade, regardless of the size or risk of the trade.
Kelly Criterion: The Kelly Criterion is a mathematical formula that helps determine the optimal position size based on the probability of different outcomes and their corresponding payoffs. It aims to maximize the long-term growth rate of capital while considering the risk involved.
Risk Parity: Risk parity strategies allocate capital based on the risk contribution of each asset in the portfolio. The position size is determined by the volatility or risk of the asset, aiming for equal risk contributions from each asset class.
Value-at-Risk (VaR): VaR is a risk management metric that estimates the maximum potential loss within a specified confidence level over a given time horizon. Position sizing based on VaR involves allocating capital in a way that limits the potential loss to a predetermined threshold.
Optimization techniques: Mathematical optimization methods can be used to find the optimal position size that maximizes a specific objective function, such as risk-adjusted returns or portfolio diversification.

Price impact is the difference between the current market price and the price you will actually pay when performing a swap on a decentralised exchange.

Price impact tells how much less your market taker order gets filled because there is not available liquidity.\nFor example, if you are trying to buy 5000 USD worth of BNB token, but there isn’t available liquidity\nyou end up with 4980 USD worth of token at the end of the trade when you pay 5000 USD.\nThe missing fill is the price impact.\nIt can be expressed as USD value or as percent of the trade amount.

Illiquid pairs have more price impact than liquid pairs.

Liquidity provider fees are included in the price impact in AMM models.

Another way to see this: AMMs usually have a trading fee, of 0.30%, for liquidity providers and sometimes for the protocol.\nThis translates to a spread of 0.6% between the best buy order and the best sell order.\nIn other words, even the most liquid AMM trade has an implicit 0.3% price impact.

In machine learning, regularization is a technique for reducing overfitting by adding a penalty term to the loss function. It is a form of regression that constrains the model to prevent it from learning the training data too well.

Regularization is a common practice in machine learning and statistical modeling. It is used to prevent overfitting, which occurs when a model performs well on the training data but does not generalize well to new data.

The process involves adding a penalty term to the loss function that penalizes the model for learning the training data too well. The penalty term is typically a function of the model parameters, such as the sum of the squared weights or the sum of the absolute values of the weights. The penalty term is added to the loss function to create a new loss function that is minimized during training.

Regularization can be used to compare different models or to tune the parameters of a model. It can also be used to select the best features for a model or to determine the optimal number of features.

Sharpe, or The Sharpe Ratio, is a widely used financial metric that measures the risk-adjusted return of an investment. It was developed by Nobel laureate William F. Sharpe in 1966.

The Sharpe ratio is calculated by subtracting the risk-free rate (such as the yield on a Treasury bond) from the return of the investment, and then dividing the result by the standard deviation of the investment’s returns. The formula is:

Sharpe Ratio = (Return of investment - Risk-free rate) / Standard deviation of investment’s returns

The Sharpe ratio helps investors evaluate an investment’s return in relation to the risk taken to achieve that return. A higher Sharpe ratio indicates that an investment has generated higher returns relative to the amount of risk taken, while a lower Sharpe ratio indicates the opposite.

Generally speaking, a Sharpe ratio above 1 is considered good, and a Sharpe ratio above 2 is considered excellent. However, what is considered good or excellent can vary depending on the context. For example, a lower Sharpe ratio may be acceptable for investments with lower risk or lower volatility, while a higher Sharpe ratio may be necessary for investments with higher risk or higher volatility.

Short selling, also known as shorting or going short, is a trading strategy in which an investor borrows as aasset, sells the borrowed asset, and then aims to buy the asset back at a lower price to make a profit.

The goal of short selling is to profit from a decline in the price of the security being shorted. In a short sale, the investor borrows shares from another investor, typically through a brokerage, and sells the borrowed shares on the open market. If the price of the security drops, the investor can buy the shares back at a lower price and return the borrowed shares to the lender, pocketing the difference as profit. However, if the price of the security increases, the short seller incurs a loss, which can be unlimited.

Short selling is a high-risk strategy that requires a solid understanding of market dynamics and a careful risk management plan.

In decentralised finance, you can build a short trade using lending protocols.

Slippage occurs because of changing market conditions between the moment the transaction is submitted and its verification.\nSlippage cannot be backtested easily, because it is based on the trade execution delays and those cannot be usually simulated\n(but can be measured).

DEX swap orders have a slippage parameter with them. You set it when the order is created.\nIf the price changes more then the slippage between the creation of the order and the execution of the order,\nthe DEX will cancel the order (revert).

The Sortino ratio is a risk-adjusted return measure that is used to evaluate the return of an investment relative to its downside risk, as measured by the standard deviation of negative returns. It was developed by Frank A. Sortino, a financial researcher and academic.

The Sortino ratio is similar to the Sharpe ratio, but instead of using the total volatility of returns, it only considers the downside volatility. This is based on the premise that investors are more concerned with the risk of losing money than they are with the risk of missing out on potential gains.

The formula for calculating the Sortino ratio is as follows:

Sortino ratio = (Rp - Rf) / downside deviation

Where:

Rp = portfolio return\nRf = risk-free rate of return\nDownside deviation = standard deviation of negative returns

The Sortino ratio is useful in comparing the risk-adjusted performance of different investments or portfolios. A higher Sortino ratio indicates a better risk-adjusted return, while a lower ratio indicates a lower risk-adjusted return.

As a rough guide, a Sortino ratio of 1 or higher is considered good, while a ratio of 2 or higher is considered excellent.

Statistical arbitrage is a high-frequency trading trading strategy that uses statistical and quantitative techniques to identify and exploit pricing inefficiencies in financial markets.

The strategy involves taking long and short positions in pairs of securities that are believed to be mispriced relative to each other.

The basic idea behind statistical arbitrage is to identify pairs of securities that are highly correlated in terms of their price movements. If the prices of these securities diverge from their historical correlation, a statistical arbitrageur will take a long position in the underpriced security and a short position in the overpriced security, in the hope of profiting from the convergence of prices.

Statistical arbitrage strategies typically involve a high level of automation, using computer algorithms and mathematical models to analyze large amounts of data and make trades in real time. These algorithms may use a variety of statistical and mathematical techniques, such as regression analysis, machine learning, and time series analysis, to identify and exploit pricing inefficiencies.

One advantage of statistical arbitrage is that it can be used in a variety of market conditions, including both up and down markets. However, the strategy can be complex and may require significant computational resources and expertise to implement effectively. In addition, as with any investment strategy, there is always the risk of losses due to unforeseen market events or unexpected changes in correlations between securities.

Stop loss is a risk management tool used by investors and traders to limit their potential losses on a trade.

Stop loss can be implemented by

Having a special order type on order book
Manually, by using market orders

A stop loss order is an instruction to automatically sell a security or other asset when its price falls to a certain level, known as the stop price.

For example, if an investor buys a stock at $50 per share and sets a stop loss order at $45 per share, the stop loss order will be triggered if the stock falls to $45 or below. At that point, the stop loss order will automatically sell the stock, limiting the investor’s potential loss to $5 per share.

Stop loss triggers can be particularly useful in volatile markets or when trading more speculative assets with higher levels of risk. By setting a stop loss order, traders can limit their exposure and losses in the event that the market moves against them, while still allowing for potential gains if the trade is successful.

It’s important to note that stop loss orders are not foolproof and can be subject to market fluctuations and gaps in trading. In addition, stop loss orders can be triggered during periods of high volatility or sharp price movements, resulting in a sale at a price below the stop price. As with any investment strategy, it’s important to carefully consider the risks and benefits of using stop loss orders and to use them in combination with other risk management tools and techniques.

In quantitative finance, Tactical Asset Allocation (TAA) is an investment strategy in finance that involves actively adjusting the allocation of assets within a portfolio to take advantage of short-term market opportunities or to manage risk.

It is a dynamic approach that aims to capitalize on market inefficiencies, mispricings, or changing market conditions.

TAA differs from strategic asset allocation, which focuses on establishing a long-term allocation mix based on the investor’s goals, risk tolerance, and investment horizon. In contrast, TAA involves making short-term shifts in asset allocation based on market forecasts, economic indicators, or other relevant factors.

The goal of tactical asset allocation is to enhance portfolio performance by overweighting or underweighting certain asset classes, sectors, or geographic regions at specific times. For example, if an investor believes that the stock market is overvalued and poised for a downturn, they may decrease their equity exposure and increase their allocation to bonds or cash. Conversely, if favorable conditions are anticipated for a particular sector or region, the investor may overweight those assets to potentially achieve higher returns.

TAA strategies can be implemented using various techniques, including fundamental analysis, technical analysis, quantitative models, or a combination of these approaches. It requires active monitoring of market trends, economic indicators, and other relevant factors that can influence asset prices. TAA may be executed through individual security selection, the use of exchange-traded funds (ETFs), or other investment vehicles.

The predetermined price level at which you plan to close out an open position for a profit. This is set when you initially establish the position. This is the price at which you want to sell and take your profit. It is important to set a take profit target and stick to it. If you don’t, you may end up holding a position for too long and lose your profit.

This can be different to position exit that is profitable. Profitable trades that have been exited due to trailing stop loss without reaching the Take Profit limit are a different category.

The number of ‘Take Profits’ may be difficult to calculate if the strategy developer has implemented their own method without using built in methods. The same goes for trailing stop loss as well.

A “token” tax is a term often used to describe tokens with transfer fees that cause deflation or redistribute trade profits to the protocol development:

Each time a token is transferred, some transferred amount is burned, redirected to a development fund or otherwise “taxed”.
Token tax is usually paid by the originator wallet that initiates the transfer. The tax is taken from the sent amount during the transfer: initiated transfer amount > received transfer amount.
Token tax may also reduce the token supply, thus creating deflationary tokens. The deflationary assumption comes from the economic theory that by reducing the supply, the value of the goods should go up. The most famous cryptocurrency having such deflationary mechanics is Ethereum and its EIP-1559 burning mechanism.
Token tax can redirect some of the transfer and trading fees to the protocol development fund. This can guarantee sustainable protocol development outside any initial fundraising.

Usually, the token tax term is not used for the native gas token on a blockchain, like Ether (ETH) on Ethereum, where any transfer fee is considered to be a natural part of the core protocol. The token tax term applies to ERC-20-like tokens that historically have lacked transfer fee features. There is no terminology standard, so different terms are applied in different contexts.

Different % amounts of “taxes” may apply to different types of transactions like buy, sell, and treasury management.

Read more about token tax in our introduction blog post.

Taxed tokens are not supported by Uniswap 3. Note that any bridged tokens cannot have transfer fees,\nso if you bridge a taxed token from Ethereum mainnet e.g. to Polygon it will work on Uniswap v3.

Trend-following is a trading strategy that follows a trend.

Trend-following is a trading strategy that seeks to profit from the directional movement of prices in financial markets. The strategy involves analyzing the historical price data of an asset to identify trends and then making trades in the direction of the trend.

Trend-following traders typically use technical analysis tools and technical indicators, such as moving averages, trend lines, and momentum indicators, to identify trends and determine when to enter or exit trades. The goal is to buy an asset when the trend is bullish (i.e., prices are rising) and sell it when the trend is bearish (i.e., prices are falling).

The key principle of trend-following is to let profits run and cut losses quickly. This means that trend-following traders will typically use stop loss orders or other risk management techniques to limit their potential losses if the trend reverses.

Trend-following strategies can be applied to a wide range of financial instruments, including stocks, bonds, currencies, and commodities. The strategy is popular among both individual and institutional traders and has been used successfully by many well-known traders and hedge funds.

One potential disadvantage of trend-following is that it can be subject to false signals and whipsaws, particularly in volatile or choppy markets. In addition, trend-following can be slow to react to sudden market shifts or changes in investor sentiment, which can result in missed opportunities or losses. As with any trading strategy, it’s important to carefully consider the risks and benefits of trend-following and to use it in combination with other tools and techniques to manage risk and optimize performance.
