Dear Edward,
Thanks again for your continued help. You are a big encouragement.
I am attaching with this mail the full AFL. Will you please check it for me? I think with my very little knowledge I have done some wrong somewhere because I cannot find the "1" or "1" printed anywhere, nor can I see written anywhere the values at cycle start & end. I may clarify here that the values that I need are the start & close prices of the same single cycle. How can I also get these prices through AddColumn?
Best regards,
Vinay
