Thread: Backtesting Spread ???

  1. #1

    Default Backtesting Spread ???

    When backtesting an EA, as it places orders, it must know what the "Spread" is to place orders properly. How does Metatrader determine what the spread is for a currency pair? I'm backtesting an EA that thinks a pair has a 25 pip spread when actually it is 8. The first order is placed 25 pips away from the actual currency value instead of 8 pips. I think it must be broker specific as on FXDD the spread is correct at 8 but Ikon Royal is incorrect at 25 (Ikon Royal's spread on the pair live is 8). Thanks

    Hi BillR,

    Strategy Tester > Symbol Properties.

    And yes it can take a while before the update of the spread.

    Hi Funyoo, Yes...under "Symbol properties" you can see what the spread is, but how can we change it??? During the week when trading is open it has the correct spread, but during the weekend it goes to a 25 pip spread until the market reopens....This makes any kind of accurate backtesting impossible. Check it out Ikon-Royal MT4 EURAUD

    I found this at MQL4.....it may be the bad news

    Any ideas??
    Thanks BillR
