运行Ibapi/TWS API脚本时获取订单Id错误

Question

我正在运行一个测试代码，该代码本应只下一个简单的订单，但每次运行它时，我都会遇到一个以前从未经历过的奇怪错误。这是一张截图https://i.stack.imgur.com/cgL3b.jpg.这是我的剧本：非常感谢您的帮助。。。

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.order import *
import threading
import time
class IBapi(EWrapper, EClient):

def __init__(self):
EClient.__init__(self, self)

def nextValidId(self, orderId: int):
super().nextValidId(orderId)
self.nextorderId = orderId
print('The next valid order id is: ', self.nextorderId)
def execDetails(self, reqId, contract, execution):
print('Order Executed: ', reqId, contract.symbol, contract.secType, contract.currency, execution.execId, execution.orderId, execution.shares)

def run_loop():
app.run()
def makeContract():
contract = Contract()
contract.symbol = 'AAPL'
contract.secType = 'STK'
contract.exchange = 'SMART'
contract.currency = 'USD'
return contract
app = IBapi()
app.connect('127.0.0.1', 7497, 999)
app.nextorderId = None
#Start the socket in a thread
api_thread = threading.Thread(target=run_loop, daemon=True)
api_thread.start()
#Check if the API is connected via orderid
while True:
if isinstance(app.nextorderId, int):
print('connected')
print()
break
else:
print('waiting for connection')
time.sleep(1)
#Create order object
order = Order()
order.action = 'BUY'
order.totalQuantity = 2000
order.orderType = 'MKT'
order.orderId = app.nextorderId
app.nextorderId += 1

#Place order
app.placeOrder(order.orderId, makeContract, order)
#wait for callbacks
time.sleep(20)
app.disconnect()

非常感谢

您可能想要调用函数makeContract。您传递的是函数对象，而不是结果。

app.placeOrder(order.orderId, makeContract(), order)

注意括号。
