tradingstrategy.exchange.Exchange class.

class Exchange[source]#

Bases: object

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.

Most of the fields are optionally and having values them depends on the oracle data indexinb phase.

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.
