Rationale
The S&P 500 broke its 7668-7703 shelf on 22 October, fell to 7612 on Friday, and today's bounce stalled at 7702.13, within a point of the 22 October high at 7702.94: a second rejection of the same ceiling. Price sits 0.64 ATR below the 20-day average at 7727, so the trend filter allows only the short side. Entry 7684, stop 7721.50 above the shelf top plus a noise margin, target 7626 just above Friday's low, a 0.80 ATR move that fits comfortably inside the reach for the 1.5 sessions before expiry. The idea is wrong if the index trades above 7721.50; it expires Tuesday at the close, deliberately before Wednesday's Fed decision. Holding one night on the short side costs under 1% of the risk; a multiple-charge day depends on each reader's provider and should be checked there. A pre-Fed drift higher is the main risk and could stop this out without any news.
Invalidation
A cash trade above 7721.50: the 22 Oct high of the broken 7668-7703 shelf (7702.94, retested today at 7702.13) plus a 0.25 x ATR14 noise margin (18.05). Above there the second rejection has failed and the idea is wrong. All levels from the S&P 500 cash series (^GSPC); MA20 7727.48 and ATR14 72.19 on daily cash bars excluding today's live bar.
