Sandy,
It is up to each trader to either follow the optimized robot trades exactly or to use the robot as a support for discretionary trading decisions.
However, backtesting proved that your idea is likely to yield disappointing long term risk-adjusted returns. Indeed, your idea is to trade mean-reversion which has only provided 40% from the robot signals total profits. 60% of the gains are created from trend-following trades and your mean-reversion approach will make you miss a high percentage of these gains. In a strong trend, if you exit on target and there's no pullback allowing for re-entry, what will you do?
