AssetIdentifier#

tradeexecutor.state.identifier.AssetIdentifier class.

class AssetIdentifier[source]#

Bases: object

Identify a blockchain asset for trade execution.

As internal token_ids and pair_ids may be unstable, trading pairs and tokens are explicitly referred by their smart contract addresses when a strategy decision moves to the execution. We duplicate data here to make sure we have a persistent record that helps to diagnose the sisues.
