Here's the test of the bottom of this rising wedge, defense of this level (which is near the point of control on the volume profile and converges with the 20 and 50dma) will be key. If ES can bounce here than it will be best to continue waiting, but a rejection of this level will be the signal to short.
The caveat of course is that this close to election time I'd be weary of entering any trade for much more than day at this point as it's best to give the markets a wide berth in the days immediately before and after Presidential elections.
