I think you are talking in scenario of scalping. But according to my point of view, stop loss with margin of 25 pips is still too low I always use stop loss at 60 pips whereas i use take profit with margin of 30 pips And so far i am successful with my strategy Take profit of 50 pips is too high and it is hardly achievable. my stop loss & take profit arrange continually modified with amendment inside my main arrange. normally i set take profit by 30 out to 50 pips and set stop loss by 15 out to 35 pips, other then in a few situation i like out to amendment inside my tp and sl out to save my self from uncertain market trend.
