Hi,

I have touble to receive the correct accout PnL from TWS, the program used to work just fine a couple month ago. However when I try to run the program again I am getting all same account PnL repeatly, I've tried everything to disconneect/reconnect, cancelPnLoperation and etc. It seems the only way get the account PnL update is to stop the program completely and re-run. 
my code is attached in below
Can anyone see the problems here? many thanks in advance!

def pnl(self, reqId: int, dailyPnL: float, unrealizedPnL: float, realizedPnL: float):
    from datetime import datetime
    self.pnl_tolerance = 1000
    finish_time = datetime(2021,6,23,6,0,0)
    while datetime.now() < finish_time:
        super().pnl(reqId, dailyPnL, unrealizedPnL, realizedPnL)
        print(datetime.now())
        print("Daily PnL. ReqId:", reqId, "DailyPnL:", dailyPnL,
          "UnrealizedPnL:", unrealizedPnL, "RealizedPnL:", realizedPnL)
        printout = "Daily PnL :: " + str(dailyPnL)
        super().cancelPnL(reqId)
        reqId += 1
        time.sleep(3)
        if dailyPnL <= self.pnl_tolerance:
            self.trigger_hit_no += 1
            self.tolerance_hit()
        else:
            self.trigger_hit_no = 0
