Quote from darkhorse:
This doesn't make much sense to me, as when you add to a position, the initial part of your position is still in play and so there is no progression from one trade to the next, simply a continuity of growth. From a risk management perspective it is still one trade as well, as the profit of the initial position is used to lay off the risk of the addition, thus keeping risk level the same or even decreasing it (adding in such a way that you are break even if you bail)- again, this implies continuity rather than a fresh play. Last but not least, generally the only reason you add to a favorable position is because you planned for it from the start, thus suggesting your initial goal was to target a unified move in stages, like a football game has quarters or a baseball game has innings.
