Into the close
MOC imbalance: NYSE prints ~3:50 ET · Nasdaq 3:55–4:00 ET
- Positive gamma: dealers absorb. A one-way MOC tends to get pinned/faded — buy-imbal drifts toward the call wall, sell-imbal gets bought.
- 0DTE-heavy tape: charm pin/rip is stronger — the last 30 min can decide the day.
- Size matters: an aggregate MOC over ~$1–2B is a real tide; it can flip 2:50→3:00.
