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.

The same three numbers on every ticker you trade.
