由于记录错误,无法连接到Interactive Brokers Api

问题描述

因此,我正在使用python交互式经纪人api,并且尝试通过交互式经纪人下达限价订单。我的代码是:

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.order import Order
import threading
import time


class TradingApp(EWrapper,EClient,Contract,Order):
    def __init__(self):
        EClient.__init__(self,self)
 
    def nextValidOrderId(self,orderId):
        super().nextValidId(orderId)
        self.nextValidOrderId = orderId
        print("NextValidId:",orderId)

def websocket_con():
    app.run()
    
        
app = TradingApp()
app.connect("127.0.0.1",7497,clientId=1)

con_thread = threading.Thread(target=websocket_con,daemon=True)
con_thread.start()
time.sleep(1)

contract=Contract()
contract.symbol = 'AMD'
contract.secType = 'STK'
contract.currency = 'USD'
contract.exchange = 'SMART'

order=Order()
order.action = 'BUY'
order.orderType = 'LMT'
order.totalQuantity = 1
order.lmtPrice = 10

app.placeOrder(app.nextValidOrderId,contract,order)
time.sleep(5) 

此代码应能够连接到已建立的纸质交易帐户。虽然我正在接受错误:

我确保已选中“启用活动客户端”和“套接字客户端”,并且信任IP地址为127.0.0.1 为什么会收到此日志记录错误?

编辑: 新的代码是:

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.order import Order
import threading
import time


class TradingApp(EWrapper,EClient):
    def __init__(self):
        EClient.__init__(self,self)
 
    def nextValidId(self,orderId):
        self.nextValidId = orderId

def websocket_con():
    app.run()
    
        
app = TradingApp()
app.connect("127.0.0.1",daemon=True)
con_thread.start()
time.sleep(1)

contract=Contract()
contract.symbol = 'AMD'
contract.secType = 'STK'
contract.currency = 'USD'
contract.exchange = 'SMART'

order=Order()
order.action = 'BUY'
order.orderType = 'LMT'
order.totalQuantity = 1
order.lmtPrice = 10

app.placeOrder(app.nextValidId,order)
time.sleep(5) 

尽管现在我得到了错误:

ERROR <bound method TradingApp.nextValidId of <__main__.TradingApp object at 0x00000136780E7508>> 504 Not connected

解决方法

我认为class TradingApp(EWrapper,EClient):是您想要做的。我认为没有理由扩展Contract and Order类。

您更改了方法的名称,它必须与超类相同。 不要将方法名称重新用作变量名称。

#def nextValidOrderId(self,orderId):
def nextValidId(self,orderId):
    self.nextValidOrderId = orderId
