DislikedHi Dave From what i have found out it appears that you enter the spread in points as in 20 for 2 pips etc . Strategy Tester as of MT4 build 509 now enables you to fix the spread by setting the value in points in the small Spread: field on the right just above Optimization. 25 points as an example means 2.5 pips. also if the data used is exported to MT4 using Tickstory (dukascopy data) the spread is set at the point of export and to change it you need to use the tickstory tool MT4 data editor. I wondered why changing the spread in MT4 wasn't making...Ignored
