Are these levels specific to same-day expirations?

The levels on this page are computed from the full option chain for SPY, QQQ, IWM, across all expirations, from the daily snapshot. Inside the GEX dashboard you can switch the expiration class to 0DTE and every level, the chart lines and the strike table recompute for today's expiration only.

Why do 0DTE traders care about gamma levels?

Same-day options carry the highest gamma in the chain, so dealer hedging of those contracts moves the underlying more on expiration day than on any other. The call wall, put wall and gamma flip are where that hedging pins, holds or flips direction — the structure behind the pins and the squeezes you see on the tape.

Do I need an account?

No — the daily email needs only an address. A free account adds the same levels on any ticker, the scanner's 0DTE preset, 3 scans and 3 AI Advisor chats a day, and a $25K paper portfolio. Seven days of Pro are free to start.

0DTE contracts carry the highest gamma in the chain, so the hedging behind them pins, holds and flips the underlying harder on expiration day than on any other. These are today's levels where that hedging changes direction — computed from the full option chain, not drawn on a chart.

What 0DTE traders read on the map

Three numbers, one read on the session.

None of this is a prediction. It is where the market's own hedging is positioned to push or hold today — the context a chart cannot show you. Decisions are yours.

Call wall — the day's ceiling

The strike carrying the most call gamma. Dealers short those calls sell into it as price rises, so 0DTE rallies tend to stall there. Above it, hedging flips and the tape can run.

Put wall — the day's floor

The strike carrying the most put gamma. Dealer hedging buys into it on the way down, so intraday selloffs tend to find support there — and accelerate once it gives.

Gamma flip — the regime line

Where cumulative dealer gamma crosses zero. Above it hedging dampens moves and the session grinds; below it hedging amplifies them. It is the line between a pin day and a trend day.
