Deathtotaxes:
At the present time, I plan to keep this experiment going until they start throwing dirt on me. So I guess at some point the experiment will either be aborted or it will turn into a long-term portfolio strategy for me.
If things do go well, increasing the position size sounds like a very good idea.
I use Scottrade so the commissions are minimal, and due to the never-sell philosophy there will only be the one commission when the position is established.
Due to the long-term nature of the experiment I don't think the commissions will be a big factor.
I read a few of the pages of that trading book by Alexander Elder on Amazon.com. It looks good. It must be pretty popular because even people selling used copies were asking $20+. I'm going to see if I can get my hands on a copy soon.
