无法使用ibapi连接python和TWS

Question

这是我的代码：

from threading import Timer
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.order import *

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('Contract Details :', reqID, '', contractDetails)

    def nextValidId(self, orderId):
        self.nextOrderID = orderId
        self.run()

    def orderStatus(self, orderId, status, filled, remaining, avgFillPrice, permID, lastFillprice, cliendId, whyHeld, mktCapPrice):
        print('Orderstatus Id. ', orderId, 'Status: ', status, 'Filled: ', 'Remaining: ', remaining, 'Last Fill Price: ', lastFillprice)

    def openOrderEnd(self, orderId, contract, order, orderState):
        print('Open Order ID. ', orderId, contract.symbol, contract.secType, '@', contract.exchange, ': ', order.action, order.orderType, order.totalQuantity, orderState.status)

    def execDetails(self, reqId, contract, execution):
        print('Exec Details. ', reqId, contract.symbol, contract.secType, contract.currency, execution.execId, execution.orderId, execution.shares, execution.lastLiquidity)

    def accountSummary(self, reqId, account, tag, value, currency):
        print('Account Summary. ', reqId, account, tag, value, currency)

    def start(self):
        contract = Contract()
        contract.symbol = 'NFLX'
        contract.secType = 'STK'
        contract.exchange = 'SMART'
        contract.currency = 'USD'
        contract.primaryExchange = 'NASDAQ'

        order = Order()
        order.action = 'BUY'
        order.totalQuantity = 2
        order.orderType = 'LMT'
        order.lmtPrice = 539.50

        self.placeOrder(self.nextOrderID, contract, order)

    def stop(self):
        self.done = True
        self.disconnect()


def main():
    app = TestApp()
    app.nextOrderID = 0
    app.connect('127.0.0.1', 7497, 0)

    Timer(3, app.stop).start()
    app.run()


if __name__ == '__main__':
    main()

当我执行这段代码时，我只是得到了基本的消息：

错误-1 2104市场数据场连接正常:hfarm错误-1 2104市场数据场连接正常: OK:usfarm.nj错误-1 2104市场数据场连接正常: HMDS未来错误-1 2104市场数据场连接正常:jfarm错误-1 2104市场数据场连接正常:eufarm错误-1 2104市场数据场连接正常:现金农场错误-1 2104市场数据场连接正常:usfarm错误-1 2106 HMDS数据场连接正常:euhmds错误-1 2106 HMDS数据场连接正常:fundfarm错误-1 2106 HMDS数据场连接正常:ushmds ERROR -1 2158 Sec-def data farm connection is OK:secdefnj

我从IBKR在线视频中复制了代码。我不知道我做错了什么。如果有任何帮助，我将不胜感激。

你已经连接上了，你只是从来没有在你的start方法中下过订单。考虑重命名start方法，因为调用Timer.start可能会让人感到困惑。

from threading import Timer
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.order import *

class TestApp(EWrapper, EClient):

    def __init__(self):
        EClient.__init__(self, self)
        self.nextOrderID = 0 # if this is init code put it in init

    def Error(self, reqID, errorCode, errorString):
        print('Error :', reqID, '', errorCode,'', errorString)

    def contractDetails(self, reqID, contractDetails):
        print('Contract Details :', reqID, '', contractDetails)

    def nextValidId(self, orderId):
        self.nextOrderID = orderId
        #self.run() you already called app.run
        self.start() # call your start function, you never did so order wasn't placed.
    
    # you missed parentId, just copy these big defs from the source
    def orderStatus(self, orderId, status, filled, remaining, avgFillPrice, permId, parentId, lastFillPrice, clientId, whyHeld, mktCapPrice):
        print('Orderstatus Id. ', orderId, 'Status: ', status, 'Filled: ', 'Remaining: ', remaining, 'Last Fill Price: ', lastFillPrice)
        #maybe disconnect when order is filled
        if remaining == 0.0:
            self.stop()

    def openOrderEnd(self, orderId, contract, order, orderState):
        print('Open Order ID. ', orderId, contract.symbol, contract.secType, '@', contract.exchange, ': ', order.action, order.orderType, order.totalQuantity, orderState.status)

    def execDetails(self, reqId, contract, execution):
        print('Exec Details. ', reqId, contract.symbol, contract.secType, contract.currency, execution.execId, execution.orderId, execution.shares, execution.lastLiquidity)
        
    def accountSummary(self, reqId, account, tag, value, currency):
        print('Account Summary. ', reqId, account, tag, value, currency)

    def start(self):
        contract = Contract()
        contract.symbol = 'NFLX'
        contract.secType = 'STK'
        contract.exchange = 'SMART'
        contract.currency = 'USD'
        #contract.primaryExchange = 'NASDAQ'#??may be ISLAND, but not needed for nflx

        order = Order()
        order.action = 'BUY'
        order.totalQuantity = 2
        order.orderType = 'LMT'
        order.lmtPrice = 539.50
        
        self.placeOrder(self.nextOrderID, contract, order)
        self.nextOrderID +=1 # always increment after use

    def stop(self):
        #self.done = True # unnecessary 
        if self.isConnected() : 
            print("disconnecting")
            self.disconnect()
        
def main():
    app = TestApp()
    app.connect('127.0.0.1', 7497, 123)

    #Timer(3, app.stop).start() #means you want to stop in 3 seconds no matter what
    app.run()

if __name__ == '__main__':
    main()
