Maybe you didn't get the pun my message. I am an Aimer from way back. I still have a column book with the pencilled numbers in it, more or less as AIM BTB showed it, for my first investments.
Buy I cheated a bit and made AIMing even simpler than AIM BTB already was. To subtract the 10% of the Trade Advice was to much work so I just ignored it, The only thing I did what this:
Buy Low - Sell High
I made money on my first investment even though the price dropped on the average. Five years later I started to make good money with Aiming(my simpleton version).
In Vortex I still have it as simple as that. I like parameter optimisation: Its so simple that I no longer need to think anymore.
