Arrow

Apache Arrow is a popular open source in-memory analytics technology kit. More information.

Autonomous agent

An agent software that acts without human intervention. Once started, there is no further need for system administration or othe work.

Backtest

Simulating the efficiency of a trading strategy against historical data.

Backtrader

An old Python based framework for strategy backtesting and live execution. See documentation.

Base token

The token you want to buy or sell in a trading pair. See also quote token.

Bucket

The (time) bucket to a time period for candle data. For example, you can have one minute, one hour or time buckets, describing for the what period of a time the candle includes the trades.

Candle

Candle, or a candlestick is a type of price chart used in technical analysis that displays the high, low, open, and closing prices of an asset for a specific time period, or bucket. More information.

Clone

Also known as fork. A product launched based on the open source code of another existing product. In the context of on-chain, usually hostile to the original product and competes from the same liquidity.

Dataclass

Standard Python way to annotate data structures. More information.

Dataset

A data bundle consisting of candles or other quantitative data sources. The most usual dataset is hourly or daily candles for multiple assets, distributed as a downloadable archive of several hundreds of megabytes.

Dataset server

The server than indexes blockchains and creates candle and other datasets for research, analysis and trade execution. Currently centralised and you need an API key to access.

Decentralised exchange

An exchange where all trades happen purely on-chain. These exchanges are public, fair, cheap and especially censorship proof. There is no middleman like a broker when you are trading on these venues, but you get equal access to the trade flow. Decentralised exchanges can be AMM based or order book based. Some of the most popular decentralised exchanges are Uniswap, Sushiwap and PancakeSwap.

Directional strategy

Drawdown

Exposure

Fastquant

Fastquant allows you to easily backtest investment strategies with as few as three lines of Python code. Its goal is to promote data driven investments by making quantitative analysis in finance accessible to everyone. Fastquant builds on the top of Backtrader. See Github repository.

High-frequency trading

High-frequency trading, or HFT for short, is a trading strategy where you do arbitration, cross-market market making or such and compete against the other actors with your technical speed. Trading Strategy is not suitable framework for HFT trading, though its data can aid to come up with good HFT strategiees.

Jupyter notebook

A popular Python based data science tool. Jupyter allows users to run data research notebooks interactively. Jupyter notebooks can be easily shared, run on your local computer or on a hosted cloud environment, both free and paid. More information.

Liquidity

Liquidity refers to the depth of the order books: how much volume a single trade can achieve without moving the price. It can be expressed as slippage or absolute depth of the order book. The latter is very easy for AMM based exchanges where the liquidity is a continuous function. Trading Strategy provides datasets for AMM liquidity in capitalgram.liquidity module.

Market neutral strategy

Market neutral strategies are trading strategies that have little or no exposure to crypto asset volatility. They are often high-frequency trading strategies, like arbitrage. Good market neutral strategies can make 10% - 20% monthly yield in cryptocurrency markets.

Non-custodial

A smart contract based service model where the owner of the assets never lose the control of the assets. This is opposite to most traditional finance services where you cannot see what happens to your money after the deposit or whether you are able to withdraw. The integrity of the service provider in the traditional finance thus needs to be guaranteted through regulation or government bailouts. The non-custodial model is specific to smart contracts and cannot be achieved without a blockchain. Read more.

Notebook

Notebook refers to an interactively editable Python script or application, mixed with diagrams and notes. The format was popularised by Jupyter notebook.

OHLCV

A typical candle contains open, high, low and close price and trade volume for a time bucket. Because on-chain exposes more data than centralised exchanges, Trading Strategy data also contains individual buys and sells, US dollar exchange rate and so forth.

On-chain

On-chain refers to any activity that happens purely on a public blockchain. It means the data and trading venues are publicly and fairly available for anyone.

Pandas

A popular Python based data analysis library. More information.

Parquet

A popular file format for large datasets from Apache Arrow project. More information.

Pine Script

A proprietary trading strategy programming language for TradingView. Read more.

A trading strategy where the source code of the strategy is not disclosed to public. Private strategies can still be non-custodial and enjoy the benefits of Trading Strategy protocol trade execution and fee distribution. :ref`Read more <Private strategies>`.

Pyarrow

Python API for Arrow library. More information.

Quote token

The token that acts as a nominator for the price when you are buying or selling. Usually this is more well-known token of the pair: ETH, BTC or any of various USD stablecoins. See also base token.

Risk-free rate

The expected return for the money that is considered (almost) risk-free. On the traditional markets, this is the tresury note or government bond yield (although you still have some risks like the sovereignity risk). In DeFi this is considered an US dollar lending pool rate, like one you would get from Aave USDC pool.

Slippage

Slippage tells you how much you will lose in a trade because there is not enough liquidity to satisfy the deal. More information.

Smart contract

An automated transactional service running on any of blockchains supporting smart contracts. Typically runs on Ethereum based blockchain and is written in Solidity programming language.

Strategy

Also known as trading strategy or algorithm. The trading strategy is the rulebook what trades to make an how. In the context of quantative finance, and especially automated trading, this rulebook can be expressed as an algorithm and trading bot that has programmed rules for every situation the strategy may encounter.

A popular US cash and US treasury note backed stablecoin from Circle. Read more.

Yield farming

Pooling assets of multiple people for passive trading strategies. Usually yield farming pools rely on liquidity mining token distribution which they immediately sell (auto compounding).
