modifying the spread for Backtest

New comment
 
Hi,

I am used to do some backtests with the data of metaquotes.

For that, i create a new folders in the hystory folders where i copy the xxx.hst files i need (usually M1) and the following files : symbols.raw, symbols.sel symgroups.raw and ticks.raw

I have notice that the spread used for backtest is fix and are equal as the last spread used before i close MT4. With this trick, i can manage the spread by waiting the spread in need and then copying the files symbols.sel and ticks.raw.

But the spread in demo account are always lower than in real accounts. I would like to know if it is possible to open those files to modify the spread value or if an other trick exist to modify the spread for backtest ?

Thanks for your help
