So one never knows otherwise if back-test gives ANY sort of indication as to how it will perform walk-forward-live-wise.
Beyond that, who knows, an EA author could have stuck his ruler to charts "burning-(much)-the-midnite-oil" and actually HAVE some kind of method for SLs, TP's, Open/Close-stops, be-damned how ticks come across them, so back-tests COULD show bad things while live in these cases would be good! (if any EA of such nature exists)

Ok, thanks for the info, very good to know! I have just noticed through empirical testing that MT4 back testing is not very reliable. It is too bad MT4 platform has no reliable back testing facility, forward testing of course is the best, but takes do bloody long time, got to have atleast 3-5 month FT to really say much, unless using scalper or other EA where market exposure is very limited
