Anthony,
Thanks again. Your results are exactly what I
am expecting but I am not getting anything close. I have attached one of
your codes and a screen capture to show you what I am getting. My Scan is
picking up many Mutual Funds as well as stocks. The mutual funds or stocks
show no resemblence to 4 crows and an engulfing bar. Could there be a
setting somewhere that is acting on the scan that I am not aware. I did check
the settings in AA but they all seem to apply to the Back Tester.
Ed
PS: How did you add the pictures to your
last message? I added this picture in an Outlook Express email
with a copy of previous text. Hope it works?
