Stormin_Norman Posted May 16, 2009 Report Share Posted May 16, 2009 does anyone know if it is possible (and how to do it) to change the spread on a pair for backtesting? clicking on symbol properties opens up the details, but i was wondering if it could be changed/edited? i have eurgbp as 2 pip spread - when really it should be at least 3.

victor21 Posted May 17, 2009 Report Share Posted May 17, 2009 Re: Changing spread size on backtest maybe you already know, but the BT take the spread you have when you do it, so if you wanna do a Bt with a spread of 3, wait for your broker to have the spread you want and run the test. Hope this will help ! ;) does anyone know if it is possible (and how to do it) to change the spread on a pair for backtesting? clicking on symbol properties opens up the details, but i was wondering if it could be changed/edited? i have eurgbp as 2 pip spread - when really it should be at least 3.

Stormin_Norman Posted May 17, 2009 Author Report Share Posted May 17, 2009 Re: Changing spread size on backtest no i run it offline. it stays offline cause if it connected the gigs and gigs of data ive loaded onto it would get wiped and replaced by the broker's feed. i was hoping somewhere i could hack it to change the spread displayed for the different pairs.

Tango Posted May 18, 2009 Report Share Posted May 18, 2009 Re: Changing spread size on backtest Try this How to Use.. 1. Install "SpreadGenerator.mq4" in \experts\scripts folder. 2. Attach "SpreadGenerator" on Target CurrencyPair Chart. 3. Input your favorite spread value. ( -10 ? OK....No problem.. ) 4. This script makes "symbols.sel" in \experts\files folder. 5. Try Online-Backtesting with Normal Current Spread and downloading Historical data. 6. Take several long breaths to calm yourself down. 7. Disconnect from the Internet and Shutdown MetaTrader. 8. Copy your "symbols.sel" and Overwrite original "symbols.sel" in \history\YOUR DEMO SERVER Accounts folder. 9. Restart MetaTrader.( DO NOT CONNECT INTERNET !!! ) 10. Try Offline-Backtesting with YourOwnSpread. 11. Say " It's crazy!! " MetaTrader always overwites "symbols.sel" when connecting Server. Don't worry about your sweet-"symbols.sel". This script is NOT perfect. Because there is no data about the file-format of "symbols.sel". http://www.4shared.com/file/106030652/701a1262/SpreadGenerator_v11.html Quote Link to comment Share on other sites More sharing options...
