get_event_contract_kline(code, pre_side=None, ktype=KLType.K_DAY, kline_source=None, max_count=1000)
Description
Get the real-time K-line of an event contract. It supports two sources: contract-level trade-price K-line and YES sub-contract order book K-line, and supports querying by direction (YES/NO) and K-line type. You must subscribe to the corresponding K-line type (e.g.
SubType.K_DAY) before querying K-lines, otherwise an error is returned.Parameters
Parameter Type Description code str Event contract code, e.g. 'EC.KXODIMATCH-26JUL140600INDENG-IND'pre_side PredSide Contract direction ktype KLType K-line type, default KLType.K_DAYkline_source ECKlineSource K-line source max_count int Maximum number of records returned, default 1000 Return
Parameter Type Description ret RET_CODE API call result data pd.DataFrame When ret == RET_OK, returns the K-line list str When ret != RET_OK, returns the error description The returned DataFrame fields are as follows:
Field Type Description code str Contract code pre_side str Contract direction ( YES/NO/N/A), see PredSidename str Contract name time_key str K-line time (yyyy-MM-dd HH:mm:ss) open float Open high float High low float Low close float Close volume float Volume Example
from futu import *
quote_ctx = OpenQuoteContext(host='127.0.0.1', port=11111)
# You must subscribe to the corresponding K-line type before querying K-lines (otherwise an error is returned)
ret, err = quote_ctx.subscribe_event_contract(
['EC.KXODIMATCH-26JUL140600INDENG-IND'], [SubType.K_DAY]
)
if ret != RET_OK:
print('subscribe failed:', err)
else:
# Contract-level trade-price K-line (YES direction)
ret, data = quote_ctx.get_event_contract_kline(
'EC.KXODIMATCH-26JUL140600INDENG-IND',
pre_side=PredSide.YES, ktype=KLType.K_DAY, max_count=5
)

get_event_contract_kline(code, pre_side=None, ktype=KLType.K_DAY, kline_source=None, max_count=1000)
Description
Get the real-time K-line of an event contract. It supports two sources: contract-level trade-price K-line and YES sub-contract order book K-line, and supports querying by direction (YES/NO) and K-line type. You must subscribe to the corresponding K-line type (e.g.
SubType.K_DAY) before querying K-lines, otherwise an error is returned.Parameters
Parameter Type Description code str Event contract code, e.g. 'EC.KXODIMATCH-26JUL140600INDENG-IND'pre_side PredSide Contract direction ktype KLType K-line type, default KLType.K_DAYkline_source ECKlineSource K-line source max_count int Maximum number of records returned, default 1000 Return
Parameter Type Description ret RET_CODE API call result data pd.DataFrame When ret == RET_OK, returns the K-line list str When ret != RET_OK, returns the error description The returned DataFrame fields are as follows:
Field Type Description code str Contract code pre_side str Contract direction ( YES/NO/N/A), see PredSidename str Contract name time_key str K-line time (yyyy-MM-dd HH:mm:ss) open float Open high float High low float Low close float Close volume float Volume Example
from moomoo import *
