Subject: [amibroker] Sequential Optimizations for independent variables

Awhile back I suggested, on the feedback site, an option to perform sequential optimizations. The response was that this is already possible, however I can't figure out how. Can someone explain to me how to run the following two optimizations sequentially, that is independently, one after another?

Opt1 = Optimize("Opt1",10,1,100,1);

Opt2 = Optimize("Opt2",10,1,100,1);

Sequential optimization would only require 200 opt cycles, while the normal opt procedure is designed for dependent variables and requires 10,000 opt cycles. Sequential opts for independent variables would, in this case, be almost 100 times faster. I bet many users don't consider whether the opt variables are independent or not... doing so could turn a two hour opt into a 1 minute opt.

AFAIK, Opt()s cannot be if()d, and their arguments cannot be changed dynamically, right?

I must be (again) missing something obvious.

many thanks,

herman
