Tomasz -
Thank you for the prompt reply, it works great, sort of.
The problem is that it only creates the composite for the watch specified in the
"define use filter" of the AA parameters. The speed is, however, much
improved.
Any other good thoughts?
Merry Christmas and a Happy & Prosperous New Year to you
and your family.

Lou,
Instead of this loop use AddToComposite WITHOUT LOOP and
WITHOUT SETFOREIGN
and use "Apply to" -> Filter instead.
This will be much faster.

Subject: [amibroker] How to Program
this More Efficiently
The following code works but takes too long. What I
want to do is make two composites each from a different watch list and each
list has about 80 symbols. I want to run the code along with my one
minute scans for signals (the scans cover only one watch list and the
composites are not used for signals). Is there a more efficient way to
code this?
regards,
lou howard
