Question on MT4 backtester

[[Deleted]]

Hi all,

I m trying to run a backtest for a EA with the same set of test data on different PC, the fuuny thing is among 5 different PCs, 2 of them are giving a very profitable result, but the backtest result from the rest of the PC are all giving poor result, then I realised the trade opening time and Price are quite different from these 2 good result PCs than the rest of the 3 Pcs, so I tried to log the Bid/Ask Price during the backtest, and I found even on the same candle, the Bid and Ask price that generated from the 2 good result PCs are different than the rest of the 3. Does anyone know what could be the probable cause?

Thanks

Tom

It may be:

• different brokers;
• different history;
• different symbol pecification;
• different period of backtest;
• etc.
