Dear all,
Lately I've encountered some backtesting problems.
Testing my system with data downloaded from http://www.alpari-idc.com/en/dc/databank.php form the beginning of 2007 till now gave a 1,500 pips profit.
Reinstalling of Metatrader, new import and period conversion of the history data gave a totally different outcome - only 100 pips.
This is not the first time of inconsistency in backtesting I\m encountering with.
Has anyone experienced similar phenomena?
Can backtesting be accountable?
