Different Results in Optimization and Backtests ?

[marsupilami]

Hi,

I am optimizing an ea TimeFrame H1 with every tick (using my own tick data & real spreads) ; it is a high-low based scalper with relatively tight stops/profits.

 

After it is finished, when I go to "optimization results" tab and double click on a specific line to run a backtest on that specific set of optimized parameters, I sometimes get quite different backtest  results (number of trades, pnl...) than the results shown in the "optimization results" tab.

 

Any idea why? 

 

Thanks

Not sure I understand. Do you mean that in Optimization MT4 will use a fixed spread vs a variable in backtest ? ( my .fxt file are built with variable spread : I use an ea to gather ticks with broker in csv format, then I use CSV2FXT to get the correct .fxt files with variable spread; backtest & optim are run on this )

All right I got it ; just needed to use "Current" in the spread drop menu and it matches the optimization results.Thanks for help.
