Falling wedge, positive divergence, completed measured move down from sHs. Looks like a solid setup to me. I'd wait for to make sure that the most recent swing low holds, then throw a 2xATR stop on that baby, and let her rip for a solid swing. I'd take that trade on a doulbe bottom bounce from the low a couple of weeks ago.
I actually haven't opened a position yet, but I usually do a 50-pip trailing stop. For me, 50 pip SL works pretty good for this time frame
