Yes it will trigger an exit signal when the pair comes back to its mean, it doesn't use a stop loss, because a rolling mean is used instead of a static mean it will simply exit once the pair comes back, profit or loss.
About 70% of my trades are profitable, not sure what the ratio would be if I didn't apply filters, it may be the same but the trades I take would have a lower risk profile.
Thanks. I had hoped for a higher success ratio, but perhaps that's unrealistic !
Do you always wait for PTF to signal an exit or do you apply your own criteria for terminating a losing trade ?
