Target is just the support below, but it could retrace after hitting the box target, or after the time projection ends.
Either way, I expect a considerable decline, after seeing a rapid shift of sentiment, right after Yellen's remarks, from massive amounts of bears, to bears who gave up, which gave us the right ingredients for a lasting top.
Disclaimer: I'm/we're long VIX calls, with spreads and out of the money call options, and short SPX via derivatives and equity
The stop here is tight, but should hold. If more conservative you could use 3x daily ATR, or go over the highest high.
I expect downside after this Friday's jobs report.
