that's secret. if i post how many points for stop loss here, then they will shake me out next time.

in general, only when trend line broken against my position and confirmed. then i'll look for opptunity to exit. of course scalp is different. i know the position is in a gain or loss just in few mins and try to exit fast if it against me. but, the probablities of the success of entry points have to be refined hundreds of thousands of time (that's the years of trading experience).
