Can backtests of demo versions be manipulated?

 

Hi everyone

Ive been playing around with a lot of EAs for some weeks now until I decided to test the Quantum Emperor EA today. I used the demo to backtest and the results were... too good to be true

Checking the reviews and comments it seems that this guy bribes ppl who blew their account by giving them back their money for a positive review. Also on youtube there are multiple people warning from this EA saying that it recently blew a lot of accounts. My backtests with the current version are on the other hand more than promising.

Is it possible to manipulate the code from the demo version to hide the failed trades in the results?

I don't think so. Unless the EA is locked down to trading on certain days and certain times. Because that means it was overfitted for those days, and those times.

If you can make the EA trade on all times, and it's still giving a good result, then it is probably good.

That's sinister. If you know this to be 100% true, then obviously it is a scam.
