In this story am I the pigeon or is it quantconnect? I want to order a private jet by credit seeing this does it happen to you often?
did you include fees and slippage? add a slippage model and run it again and see if it still beats SPX
Yes moreover the fees make about 45% of the profit (enormously high). no I did not integrate the slippage. that could be the origin of the problem
Run the backtest again with the slippage integrated. Still a little strange that the fees would be so high. What kind of fees is that? But still even with the fees included, you are still earning $2+ million. Let us know what the result is with the slippage integrated.
As for commissions, I used the Interactive broker fee model. I have not put a slip model but I am currently implementing it. I will post the results
and I read something that this is the most important part to take into account for a serious backtest
