I wrote the following script to delete daily data bars in an intraday
database. Scripts really run slow, like many hours, and I was
wondering if this could be coded in AFL and run as a Scan. I run a
scan to export all intraday data and it takes a few minutes while the
script runs for hours and hours.
I just want to know if I can delete daily bars using an AFL formula
in Analysis>Scan using the object model, or some other way.
Thanks,
Barry
