Rationale
The S&P 500 closed Thursday at 7663, its worst session since July, and today it is holding between the 7612 low and the 7660 high, 1.21 daily ranges below its 20-day average (7733). The breakdown left a shelf at 7668-7703 (the 19-20 October lows and the 22 October gap-day high), and the idea is to sell a pullback into it at 7690, not to chase the current price. The idea is wrong above 7721.50, a quarter of a daily range above the gap-day high: if the market reclaims that level the breakdown has failed. The target is 7627, a retest of the support zone, two times the risk. Validity ends at Tuesday's close so the idea is not exposed to the Fed decision of 28 October or the GDP and PCE data of 29 October. If 7690 is not reached by then the idea is cancelled. Holding costs on the short side are estimated below 2% of the risk over the three nights; a weekend gap can still move the price through the stop.
Invalidation
A cash close or trade above 7721.50, i.e. the 22 Oct gap-day high (7702.94) plus a 0.25 x ATR14 noise margin: above there the breakdown of the 7668-7703 shelf has failed and the idea is wrong.
