Indexes Gap Up Into Negative GEX With 0DTE Pin Risk at Critical Walls

Monday opens with SPY gapping up +0.31% to 762.33 — already trading above Friday's 760 call wall — while QQQ leads with a +0.57% cash gap to 708.39, punching through its own 705 call wall. But the options market is telling a cautionary tale: all four indexes carry deeply negative net GEX, meaning dealers are net long gamma and can lean against directional moves, creating two-way friction as the morning develops.

The big macro backdrop is a week packed with mega-cap earnings and the midterm elections approaching — headlines are already flagging it as 'tech's make-or-break week.' IWM is the odd one out with a flat gap (+0.11%) and a bullish trend bias score of 54 (77% confidence), while SPY and QQQ trend systems read pure chop. With 0DTE volume at 80.1% of SPY flow and max pain sitting well above current prices on every major index, the gap-up open deserves skepticism unless it gets clean follow-through above the prior session's highs.
