MT5 loses old backtest results


Hi to all folks!

I've ran lots of backtest with MT5, some of them requiring multiple days of calculation, and approximately each 2-3 months all previous backtest result are not available anymore.

Is this happened to you too?

There is a way to backup current backtest result in order to recover it later just in case of this issue experiencing again?

Thank you very much in advance,

have a great day,

Roberto LM
