Four questions, one ladder
Every line on the chart answers something a 0DTE trader asks all day. This is where each one sits on the strike ladder.
Illustration, not live data.
- Call wall major +
Where are the walls?
The strike with the most positive gamma, by volume and by open interest. Drawn on the price chart with its history, so you see when it moves.
- Spot
Where is the flow now?
Max change shows the strikes whose gamma changed most in the last 1–30 minutes. Dots on every bar show where each strike stood before.
- Zero gamma
Which regime?
Spot above it: moves tend to be absorbed. Below it: moves tend to run. The line at the top of the chart says which, and how far the flip is.
- Put wall major −
Where does a sell-off stall?
The strike with the most negative gamma – often where a sell-off first meets resistance, or speeds up if it breaks.

Questions
What is GEX?
Gamma exposure measures how much option dealers have to buy or sell the underlying as price moves. Large positive levels tend to slow price down; negative ones can speed it up. Read the guide.
How often does the data update?
Every second during US market hours (09:30–16:00 ET). The open interest levels are set before the open, at 08:30 ET. Outside market hours the levels don't change.
Is there a commitment?
No. Pay monthly or yearly and cancel whenever you like – access runs to the end of the period.
How do I pay?
By card through Stripe. We never see or store your card number. Receipts and cancellation are under Account.
Is this investment advice?
No. GEX BASIC shows data and is an analysis tool; your trading decisions are your own. See the disclaimer.
