app.reqContractDetails(1, contract)返されるデバッグ利回りNone

この問題に関する情報は限られているようです

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract


class TestApp(EWrapper, EClient):
    def __init__(self):
        EClient.__init__(self, self)


def error(self, reqId, errorCode, errorString):
    print("Error: ", reqId, " ", errorCode, " ", errorString)


def contractDetails(self, reqId, contractDetails):
    print("contractDetails: ", reqId, " ", contractDetails)


def main():
    app = TestApp()

    app.connect("127.0.0.1", 7496, 0)

    contract = Contract()
    contract.symbol = "BYND"
    contract.secType = "STK"
    contract.exchange = "SMART"
    contract.currency = "USD"
    contract.primaryExchange = "NASDAQ"

    print (app.reqContractDetails(1, contract))

    app.run()
    app.reqContractDetails(2, contract)


if __name__ == "__main__":
    main()

アップデート：

ブライアンのアドバイスに従って次のことを試しました-まだ何もしません:(:

class TestApp(EWrapper, EClient):

    def __init__(self, addr, port, client_id):
       EWrapper.__init__(self)
       EClient.__init__(self, self)

       self.connect(addr, port, client_id)
       thread = Thread(target=self.run)
       thread.start()


def error(self, reqId, errorCode, errorString):
    print("Error: ", reqId, " ", errorCode, " ", errorString)


def contractDetails(self, reqId, contractDetails):
    print("contractDetails: ", reqId, " ", contractDetails)


def main():
    app = TestApp("127.0.0.1", 4002, 0)
    app.run()

    contract = Contract()
    contract.symbol = "BYND"
    contract.secType = "STK"
    contract.exchange = "SMART"
    contract.currency = "USD"
    contract.primaryExchange = "NASDAQ"

    app.reqContractDetails(1, contract)
    time.sleep(3)
    app.disconnect()

if __name__ == "__main__":
    main()

それは私のアドバイスではなかったと思います。リンクされた質問の正確なコードといくつかのコメントを次に示します。

print (app.reqContractDetails(1, contract))最初のコードでは、何も返さないメソッド呼び出しを出力していることに注意してください。プログラムは非同期です。つまり、何かを要求すると、後でコールバック メソッドに返されます。この場合、reqContractDetailsデータは後で に返されますcontractDetails。
