如何通过 IB TWS 通过 python 检索延迟的股票价格

Question

这是试图通过盈透证券 (IB) TWS 检索 AAPL 延迟股票价格的代码。

但是，没有检索到任何数据。

如您所见，已调用 app.reqMarketDataType(3) 来设置延迟数据。 （3是延迟）

我已在 IB TWS 中登录模拟账户并确保选择了“启用 ActiveX 和 Socket 客户端”。

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

import threading
import time
   
class IBapi(EWrapper, EClient):
    def __init__(self):
        EClient.__init__(self, self)
    def tickPrice(self, reqId, tickType, price, attrib):
        if tickType == 2 and reqId == 1:
            print('The current ask price is: ', price)

def run_loop():
    app.run()

app = IBapi()
app.connect('127.0.0.1', 7497, 123)

#Start the socket in a thread
api_thread = threading.Thread(target=run_loop, daemon=True)
api_thread.start()

time.sleep(1) #Sleep interval to allow time for connection to server

#Create contract object
apple_contract = Contract()
apple_contract.symbol = 'AAPL'
apple_contract.secType = 'STK'
apple_contract.exchange = 'SMART'
apple_contract.currency = 'USD'

#Request Market Data
app.reqMarketDataType(3)
app.reqMktData(1, apple_contract, '', False, False, [])

time.sleep(10) #Sleep interval to allow time for incoming price data
app.disconnect()

Answer 1

代码工作正常。问题是，除非您得到 tickType 2（实时询问），否则您不会打印，延迟询问是 tickType 67。
