HI, I try to optimize 2 variables:
'buy' : value in program (as extern): 0.75 , start: -0.2, step:0.05, stop: 0.9
'close': value in program (as extern): 0.2, start 0.3, step: -0.05, stop: -0.6
when I run that on spx500 (the broker is fxcm), for a 1 month check (1.10 to 2.11), on 'open prices only',
The best result is different every time I run it even one after the other. (the spread for this is always 5 and never change)
and more than that: when I take from one of the result the best one, and write the variabiles in the program that new values,
take the extern out and run now again without optimization, I get other results that are very different than those above.
My question is: how all that can be. what am I doing wrong.
Thanks in advance
