Stop Loss Issues

If I change my percentage that I am multiplying by my close price to create my limit, it does not change the results of a backtest. 

Taking 0.98 and changing to 0.99 should yeild a different result but is not. How can I fix this? New to Quantconnect and the tutorials didn't make stop losses click for me.

Thanks!

Update Backtest

Hi Gage,

The issue here is that the algorithm uses SetHoldings and explicit orders to manage positions. If the intention of

weight = self.SetHoldings("SPY", 0.99)

is to calculate the number of shares to trade, we should use the CalculateOrderQuantity method instead.

See the attached backtest for the full solution. Also, consider reviewing our documentation and completing more Bootcamp lessons to get more familiar with our API.

Best,
Derek Melchin
