[amibroker] why is optimization for a large number of stocks so much slower?

["stevenjhamon" <stevenjhamon@xxxxxxxxx>]

I have a rotational system that takes about 30 min to optimize when I run it on a basket of 20 stocks. When I run it on a basket of 300 stocks, it takes more than 5 days, which is proportionally much greater.

I use esignal datafeed, optimize with cmae and have 5 variables, 17177 optimization steps.

Is there any way to speed this up? I tried changing the number of bars to load and memory used in the preferences but it didnt help.
