Hi,
I'm new to QC and get my first experiences with Phyton. Now i'm trying to implement a simple stop loss via stop order to my algo. I buy the assets via SetHoldings in OnData.
Then I want to add a stop order in the OrderEvent:
def OnOrderEvent(self, event):
self.AveragePrice = self.Portfolio[event.Symbol].AveragePrice
self.StopMarketOrder(event.Symbol, -self.Portfolio[event.Symbol].Quantity, self.AveragePrice*0.8)
The backtest with this code is not possible: It doesnt bring an compiler error etc but it crashes. The backtest starts and cant be finished. Is there an referencing problem here?
Thanks for your help, Chris

Hi Chris
OnOrderEvent is called not only when an order is filled, but whenever a trade status changes, including a trade submission. Since you're submitting a stop market order within it, it will be called recursively as an infinite loop.
Since we only want a stop order when
we'll have to include an if condition to filter what we want:
