The kolachi method can earn you big gains if the system is adhered to, so I don't doubt for a moment that Mr. Kolachi earns any less than he states.
I trade conservatively so I take small profits and try to protect my equity. I had 27 trades last week with only 4 losing trades. The losing trades were at the end of the week when I bacame over confident and traded outside of the kolachi trading system. The losses I had in 4 trades wiped out my week's earnings. I was up over 200 pips for the week and it was a breeze but I became greedy, stupid, and blinded by my own success.
