Hi David,
Totally agree that things need to be in the right ballpark between demo trades and either mt4 of EA studio backtester.
However from a quality point of view if MT4 backtester isn’t matching the EA studio as you have shown then mistakes have 100% been made and that is the easiest place to start.
Haha, yup I would say trying to do too much again, but I understand the habit ;-)
