If you want to make a statement Ruong, tell us in what instrument and what you were "scalping" under what time frames and what "sclaping stop loss" strategy you used. Because I assume not every "scalping" trade resulted in a profit, right? If you want to be a rock start, show us full level statistics.
I think you're referring to ROMAD. I actually came up with this concept before I knew about it...I called it the Sharper method (from the Sharpe method) where I changed the capital allotted to the capital at risk based on 1SD. The idea being that for a shorter term trade it doesn't really matter how much capital is allotted so much as how much capital is at risk.
