I was responding to the middle paragraph about QuickAFL in AA. My statement stands as I believe it already works the suggested way. I did not try the artificial reference ticker. Possibly I am missing the point.

So you didn't try what was suggested and you concluded that it doesn't make sense?

This does not make sense to me. You pick the dates you want tested. There is no other way.

 

This assumes that if you have data back to say, 1990, and you test from 2000 to present, AA only runs from 2000 to present (plus some number of days earlier to insure reasonably correct results as required). I'm sure this is correct since I can see the speed change when I test on less data. Try testing one month, then test 20 years. It's obvious this is true.

First, thanks again for adding the OLE charting properties and methods
to 4.73.  They work out great.

Your previous response about Quick AFL in charting prompts me to ask
if you have considered employing it in AA methods.  Those who
backtest, scan, etc. would realize speed increases if the From/To
dates were utilized with a pad similar to what you described in
QuickAFL in charting.  AB is faster than anything else out there, but
alas, we always want more speed.  Have you ever considered this, or
perhaps it has issues - maybe in the RT area ?

FYI at present, I utilize an artificial reference ticker that is
written out based on the From date minus 1 year through the end date
and then imported.  It was the best approach that I could come up
with, and it speeds up a number of AA applications.
