dear all
Can any one explain, why we get diffetent results in MQ5 strategy tester results for the same EA with same settings and same time frames at different times
some times huge profit
some time loss
why ?
is it due to change in history data and
possibility of ba change in trend with time
for instance I was ready with an EA based on bullpower oscillator, right from march 2012 for ATC2012,Which showed only profit in strategy tesrer
,but near sepember 2012 it gave me negative results only
