orderTicketX=self.MarketOrder(self.ticker1 , self.xTradeQty)
orderTicketY=self.MarketOrder(self.ticker2 , self.yTradeQty)
avgXfillPrice=orderTicketX.AverageFillPrice
avgYfillPrice=orderTicketY.AverageFillPrice

In the above code, in backtesting, I am getting the average fill price as 0. Is there something that I am doing wrong?
