I've been working on an automated forex system that at this point seems too good to be true. I first programmed it into a 60min EUR/USD chart going back 3 months, and then did some minor tweeking with the indicators. To avoid the pitfall of optimizing I then switched it to a 90 min chart without making any more changes, as this is the timeframe I orignally planned on trading. I've also plugged it into 90 min charts going back 3 months on all 8 major pairs and it returned at least 50 pips and as much as 600 on all of them! It is a low variance method so to trade 1 10k lot in all 8 of them would have only required about $1k-2k USD, making the % returns astronomical. So, I am at this point assuming I am missing something and this is too good to be true. Help me figure what that is! I have it set to figure in the commissions I will be paying, and I have it programmed in to calculate 1 tic pip slippage both ways. Think I should raise this? I am using neoticker to test this and I plan to use it to automate if I can't find any problems. Are there any other ways I can have it simulate real life trading more accurately?
