AssetIdentifier#

tradeexecutor.state.identifier.AssetIdentifier Python class in Trading Strategy framework.

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.

__init__(chain_id, address, token_symbol, decimals, internal_id=None, info_url=None)#

Parameters:

chain_id (int) –
address (str) –
token_symbol (str) –
decimals (int) –
internal_id (Optional[int]) –
info_url (Optional[str]) –

Return type:

None
