Interactive brokers TWS API Python 获取账户余额

Question

我正在尝试获取帐户余额并将其存储为变量。 accountSummary 值中有余额。我正在使用 print 来验证 var bal 是否存储了数据。 Print(bal) 将在终端中显示信息，但不会将其打印到文件 balance.txt。如果先前执行的代码中的 orderid 示例工作正常，为什么 Balance 不能正常工作？

from ibapi import wrapper
from ibapi.client import EClient
from ibapi.utils import iswrapper #just for decorator
from ibapi.common import *
import math
import os.path
from os import path

class TestApp(wrapper.EWrapper, EClient):
    posns = []
    fname = 'fname.txt'
    def __init__(self):
        wrapper.EWrapper.__init__(self)
        EClient.__init__(self, wrapper=self)

    @iswrapper
    def nextValidId(self, orderId:int):
        print("setting nextValidOrderId: %d", orderId)
        self.nextValidOrderId = orderId
        file = open("orders.txt","w")
        file.write(str(orderId))
        file.close()
        # here is where you start using api
        self.reqAccountSummary(9002, "All", "$LEDGER")

  
    @iswrapper
    def accountSummary(self, reqId:int, account:str, tag:str, value:str, currency:str):
        bal=(value)
    
        file = open("Balance.txt","w")
        file.write(bal)
        file.close()
   

   

    @iswrapper
    def accountSummaryEnd(self, reqId:int):
        
        # now we can disconnect
        self.disconnect()
   
def main():
    app = TestApp()
    app.connect("127.0.0.1", 7497, clientId=123)
    app.run()

  
if __name__ == "__main__":
    main()

Answer 1

您每次都在覆盖文件而不是寻找余额。使用这个

def accountSummary(self, reqId:int, account:str, tag:str, value:str, currency:str):
    if tag == "CashBalance": # or whatever you want
        with open('Balance.txt', 'a+') as file: #append, create if doesn't exist
            file.write("%s, %s, %s, %s\n" % (account, tag, value, currency))
