get_event_contract_snapshot(code_list)

Description

Get the snapshot data of event contracts, including real-time quote fields such as latest price, cumulative volume, YES/NO best bid and ask, etc.
Parameters

Parameter Type Description

code_list list List of event contract codes, e.g. ['EC.KXODIMATCH-26JUL140600INDENG-IND']; a single str is automatically wrapped into a list

Parameter	Type	Description
code_list	list	List of event contract codes, e.g. `['EC.KXODIMATCH-26JUL140600INDENG-IND']`; a single str is automatically wrapped into a list

Return
