I'd like some input on how to best handle a reversal entry. For example, let's say you're trading your favorite stock. You see it approaching an established support level and go along 1/4 above support. Then the terrible happens, your trade goes against you by let's say $1 and you're stopped out of your position. Now, assuming that you wish to now reverse your position and go short, what's the best way of going about in doing this? My logic for the position reversal would be that support should turn to resistance. How far below support does the stock have to sink in order to say that the level has truly been breached? I would think if it goes $1.50 below support that would mean it is no longer a valid support level. Now, do we wait for it to come back up to that support level and bounce down, confirming that support has now turned to resistance? Or do we just go short when the stock drops over $1.50 from previous support levels?
