[amibroker] Optimzing different on different time frames

["Carl Vanhaes" <carl.van@xxxxxxxxxx>]

Have you ever noticed that some systems work better on specific time 
frame whatever the optimization settings?
Using TimeframeSet I was wondering if someone has tried to use 
different time frame as optimisation values, for example, optimize a 
given system on 5,10,15....240 minutes using TimeFrameSet in the 
formula, something like:
timeframe = Optimize( "Time_frame", 300,60,3600,60 ); 
TimeFrameSet(timeframe);

I tried this and ran an optimisation; it worked but gave totally 
inaccurate results: when I tested the system on the best time frame 
coming out of the optimisation it gave totally other (and of course 
worst) results.

Any advice?
Carl
