When you take a small pilot position looking for a turn, you get a wider stop, and then if the trade starts working a profit cushion. The game is really ramping up that position at the right time where you can tighten up the stop and get large size before the move starts. Ramp it up too early and you get stopped out, and perhaps then miss the move when it does occur. Ramp up too late and you're messing up the risk/reward and if the move is fast enough missing a big portion of the move or buying too late.
