SPY pinned at put wall open; ADP beat and 0DTE structure tilt cautiously bullish

Futures are flat into Wednesday's open with SPY pre-market last at 758.00, sitting between the 759 put wall and the 760 call wall — a one-dollar GEX corridor that defines the entire morning setup. ADP came in at 122K new jobs versus a 117K estimate, the strongest print in 16 months per headlines, which should provide a soft tailwind. But VIX ticked up 0.87% overnight to 16.24 while SPY pre-market volume was only 31,408 shares — thin participation that limits conviction ahead of the 10:00 ET ISM Services print.

The real risk event is the 10:00 ET ISM Services PMI (est. 53.8) with embedded sub-components including prices paid (prior 70.7) — a hot read would stoke inflation concern and potentially push toward the SPX 7600 put wall. Dow headline weakness tied to Trump/Iran comments and a Palo Alto earnings slide add negative single-stock noise, but QQQ pre-market is nearly flat at 746.46 and IWM is showing -0.26% drift to 289.85. The structure is tight and event-heavy — expect the first hour to be defined by how ISM prints.
