Well, as it was a kind of AIM inspired scale trading, I'll guess it's not too off topic.
Scale trading is: buy at a drop of X% (and again and again) and sell at the next higher point (scale). So start with a buy at 10, buy at $9, buy at $8.10, sell all $8.10 shares at $9, etc.
My version varies the exit point. I noticed that AIM sells less shares than it buys (when buy and sell are equally far away from the AIM mid point). So my exit point became: sell for a 10% profit with 90% of the shares (so you'll need about a 20% rise). That's all!
