Annual return>40% for SP500. Hope I can find someone that can work together.

The returns aren't that great when you look at the drawdowns. I can spot drawdowns larger than 46%. So at 50% position sizing it's more like 20% compounded with 23% DD.

 

Also wonder if it's long-biased. Notice 2011 is the only post-crash down year in his sim.

 

Clearly long biased. 2001, 2008, 2011. Most probably a type of dip buyer.

Have you done the Monte Carlo simulation? I also think you need to do more walk forward out of sample test before going live. See image,

 

Yes, it can pass the out of sample test.
Amibroker has walk forward optimization test and my system can pass it.
Thank you.

 

Why did you leave out the details about drawdown and other metrics?
