Exchange

Exchange information and analysis.

class tradingstrategy.exchange.ExchangeType

What kind of an decentralised exchange, AMM or other the pair is trading on.

Note that each type can have multiple implementations. For example QuickSwap, Sushi and Pancake are all Uniswap v2 types.

uniswap_v2 = 'uni_v2'

Uniswap v2 style exchange

uniswap_v3 = 'uni_v3'

Uniswap v3 style exchange

sushi_v3 = 'uni_v3'

Sushiswap v3 style exchange

class tradingstrategy.exchange.Exchange

A decentralised exchange.

Each chain can have multiple active or abadon decentralised exchanges of different types, like AMM based or order book based.

The dataset server server automatically discovers exchanges and tries to add meaningful label and risk data for them.

Regarding 30d and life time stats like buy_volume_30d: These stats calculated only if exchanged deemed active and we can convert the volume to a supported quote token. Any unsupported token volume does not show up in these stats. Useful mostly for risk assessment, as this data is not accurate, but gives some reference information about the popularity of the token.
