I am writing a service to work through the TWS API based on the Python language. Faced a problem when placing an order. these code are which I'm using, and always it says
waiting for connection
waiting for connection
waiting for connection
waiting for connection
I know that the problem is connecting API via orderId, but I don't know how to fix them. Through the API settings, I checked everything that I need. Like Enabled activeX and socket client.
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 orderStatus(self, orderId, status, filled, remaining, avgFullPrice, permId, parentId, lastFillPrice, clientId, whyHeld, mktCapPrice):
print('orderStatus - orderid:', orderId, 'status:', status, 'filled', filled, 'remaining', remaining, 'lastFillPrice', lastFillPrice)
def openOrder(self, orderId, contract, order, orderState):
print('openOrder id:', orderId, contract.symbol, contract.secType, '@', contract.exchange, ':', order.action, order.orderType, order.totalQuantity, orderState.status)
def execDetails(self, reqId, contract, execution):
print('Order Executed: ', reqId, contract.symbol, contract.secType, contract.currency, execution.execId, execution.orderId, execution.shares, execution.lastLiquidity)
def run_loop():
app.run()
#Function to create FX Order contract
def FX_order(symbol):
contract = Contract()
contract.symbol = symbol[:3]
contract.secType = 'CASH'
contract.exchange = 'IDEALPRO'
contract.currency = symbol[3:]
return contract
app = IBapi()
app.connect('127.0.0.1', 7497, 123)
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 = 1000
order.orderType = 'LMT'
order.lmtPrice = '1.10'
#Place order
# app.placeOrder(app.nextorderId, FX_order('EURUSD'), order)
#app.nextorderId += 1
time.sleep(3)
#Cancel order
print('cancelling order')
app.cancelOrder(app.nextorderId)
time.sleep(3)
app.disconnect()
