I do notice there is a strange observation while I don't agree with your max pain theory.
Most of the time the stock will be closed very close to a strike on expiration day. For example, if the enclosure strikes are 95 and 100 and stock is 97 now. It will be closing at 95.xx or 99.xx most likely tomorrow.
I think this is a scam but I haven't follow them for a long time. Just a funny thinking.
What I am saying is 9 times out of ten you can pick any stock one or two weeks before options expiration. Look at the max main and if the stock is not off of that you can by options that will be in the money when MAX PAIN is hit and you will make money because it will close at MAX PAIN on the nose
You are saying that MAX PAIN is always right around what the stock is trading at any given time and that is just not true.
Look at LDK yesterday MAX PAIN was $40 and it was trading at $70 They met on earnings and blew away revenue forecasts and it will close at $40 tomorrow.
Its $49 right now and I'll bet you it closes at $40 on the nose tomorrow.
