It's because his last name is WHITE obviously

Grow up. On the internet we don't know for sure that if the person on the other side is black, white or blue. Nothing racist was even said, was it? Did I miss Shaun type up a really condescending racist reply and then quickly delete it?
To bring it back to trading, he is correct in what he says. There is a BIG difference between a live back test and a sim (either using practise mode or a system you have developed yourself) so he actually offered very good, free advice. It looks like you have found a good edge, congratulations! Seriously, that is something many many people on here would love. Please don't use any sort of loss recovery. Instead look at a variation of Kelly Criteria or similar techniques to squeeze as much profit from your edge as you can; there is plenty of good reading on the internet.
Don't know or care if you are white or black, hope you are green and not red. <<< I should get into poetry.
