I am step by step approaching the conclusion that I should leave the robot working and don't touch it. It is backtested and optimized that way anyway. If I will switch it off because of trading sentiment, I will sometimes save one stoploss, sometimes will I not have profit I could have. So in the long term sum, it is breakeven.
My only concern is that the trading window is too wide, at least for EURCHF and USDCAD. So I better don't trade after 1:15 CET at all...

Of course, my "trading window too wide" theory is confirmed by my own backtests Until Oct 2008, the wider window performed well, but since Oct 2008 really lot of trades after 1:15-1:25 suck for this pair. If you look at graphs, you can see that the market just gets from the small-ranging phase into trending phase sooner for many days. IMHO FAPT developers backtested-optimized trade range bounds somewhere in October last time, so they don't confirm anymore to current market conditions.
