☕SPX Zero DTE Playbook – Oct 21, 2025

📍 Yesterday’s Close: 6735.13
🎯 Today’s Battle Zone: 6700 – 6750


🧭 Market Context

After Monday’s balanced close near 6735, the data shows a fairly even tug-of-war between calls and puts, but the edge slightly favors call positioning above 6730–6750. Dealers have built heavier exposure around 6700–6750, which suggests that intraday volatility will likely compress within this band until a strong directional catalyst appears.


📊 Key Levels Based on Open Interest & Volume

Zone TypeLevelObservation
🔴 Call Wall (Resistance)6750Heaviest call buildup; price likely stalls here without strong momentum.
🟡 Magnet Zone6725–6745Where most volume & OI overlap; expect chop and fakeouts.
🟢 Put Wall (Support)6700Strong put defense. If broken, momentum could accelerate lower.
⚠️ Secondary Floor6675Weak support — if breached, sellers may press toward 6650.

👵 Grandma’s Bias (Data Over Feelings)

“We’re dancing between two walls today — don’t fight the magnets.”

  • Bias: Neutral-to-Bullish early, turning defensive if 6700 breaks.
  • The magnet sits at 6730–6745, which should attract price action into the first 60–90 minutes.
  • Above 6750, we enter an overextended zone where buyers may fade.
  • Below 6700, expect an acceleration toward 6675–6650 as put volume increases.

🧩 Grandma’s Notes

  • Magnet Level: 6730–6745 (expect “ping pong” behavior before directional push).
  • If Bulls defend 6720+, they can squeeze into 6750.
  • If Bears reclaim 6700, momentum favors downside.
  • No strong macro shock = market likely pins around 6730–6740 for much of the session.

🧠 Grandma’s Takeaway

“It’s not a breakout day, it’s a patience day.”

  • Don’t chase moves into 6750 — that’s resistance.
  • Don’t fight support near 6700 — that’s buyer territory.
  • Wait for confirmation candles before joining a breakout.
