Ok i solved the issue with strategy tester and i get 90% Quality on both platforms with same results as i understand the quality must be 90% not 89.82% but 90% for atleast some reliability i choosed to took 1 year instead of 2 years for both MT4 and it seemed it worked and today it gaved good results live demoing so now i believe there is not that unreliability with strategy tester but one needs to test with atleast 1 year data and must 90% not even 89.94%-82% as i understood.
