Hi,

I think everyone did backtest before live account,I have a confused about that.

same ea,same setting input,same spread and same broker,why result are huge different?
please find attachment,one is BT with dukascopy ticket with "tickstory" ,another is BT with pepperstone tickets with Birt's "ticket date suite"

both of them i used pepperstone BT.

which result should I trust?

The big drop is only due to your last position which was still opened at the end of your tested period. So the backtester closed it automatically at the end (in loss in your case).

I knew that,test time is same,but one is good result and another is margin call.."NONE" means can't trust backtest even 99% or 99.9% quality??

"NONE" means that the only valid result is forward on a Live account.

Backtest should be used ONLY to confirm that the EA is trading as per the rules ... nothing else.
