Wait For A Top To Develop Before Shorting

SPY is set to gap up and open at 117.6, so SPY has reached my 117.5 target. I expect 117.5 to be strong resistance but I also expect it to take some time for a top to develop so if you short today I would short with long term puts because you might be holding them for a while. Currently breadth is 10:1 in favor of the bulls, if it stays this high then I wouldn't even bother shorting and instead would try to dip buy SPY on a break. Wait for a day where the breadth is nearly equal to open a large short position. SPY will bounce the first time it hits trendline A, so keep that in mind.
