Backtest result different after 2 months

 

Hello,

using MT5 2006 I did a backtest about 2 month ago for which I have the full report. Now suddenly the results are different no matter if I use MT5 2006, 2007 or 2015. I cannot reproduce the same result as 2 months ago.

Did Metaquotes change the backtest tick data recently ?
