Results are discarded when the EA settings are not profitable. You can show them by right-clicking on the optimization window and deselect “Skip useless options”.
Of course, more comprehensive information on this and other optimization features is available on the MQL forums.
I already know about skip useless options.
All the passes are showing up but every one has 0.00 as profit/loss.
So there seems that of something that prevent the prize to be calculated.
I have looked in some forums to find answer but not found anything yet.
So if you have some ideas I would appreiciate that.
The best advice I can suggest is to nail down a set of working parameters via the “single” back-testing method and then see if those settings work in the optimisation.
