Hi Brian
I appreciate all your help. I'm slowly reading and trying to
understand all that you have presented. Please give me some time to
figure all this out. I went into my settings in the AA window and I am
making some changes.
First thing I noticed was that "min. shares" was set to .01
I changed it to 1.
I'm reading through some help files as well (in regards to the AA
window "settings" button.)
I just wanted to send you this quick note to let you know I'm working
on it.
Thank you again
Walter
