query_contract_delivery

这个不是CtpGateway标准内置的函数吧，自己修改的需要打日志排查了

我看是内置的函数，但不知道为啥调用query_contract_delivery时，对应的回调函数onRspQryTradingAccount没有运行，请问为什么回调函数没有响应呢

main_engine = MainEngine() ctp_setting = load_json("connect_ctp.json") main_engine.add_gateway(CtpGateway) main_engine.connect(ctp_setting, "CTP") account_gateway = main_engine.get_gateway("CTP") trade_records = account_gateway.query_contract_delivery()

main_engine = MainEngine() ctp_setting = load_json("connect_ctp.json") main_engine.add_gateway(CtpGateway) main_engine.connect(ctp_setting, "CTP") account_gateway = main_engine.get_gateway("CTP") trade_records = account_gateway.query_contract_delivery()请问大神们为什么trade_records 返回的是None

请问veighna trader 社区版使用SinNow仿真交易账号登陆CTP接口时，出现行情接口报错是什么原因？
