🔎 Scanner — every ticker on one row
The option book of every ETF, stock and futures contract, one row each, rebuilt every night. Tick the states you care about — short gamma, near a wall, IV rank high or low, something changed — and the table shrinks to the tickers that match. Click a row for its card.
💡 Think of it as a search box for the option market
You do not need to know which ticker to look at. You describe the situation ("dealers short gamma, within 1.5 % of a wall, IV rank under 20") and the Scanner lists every ticker in that situation tonight.
In 30 seconds
- Pick Market: All · ETFs · Stocks · Futures (all open to everyone).
- Click a chip — say Short gamma. The number on it is how many tickers match.
- Click a second chip — a ticker must match all the chips that are on.
- Click a ticker's row for its card; click the column headers to sort.

The chips
| Chip | A ticker matches when… |
|---|---|
| Changed tonight | Something is different from the session before (see Tonight). |
| Bigger move expected | Its move grade is 4 or 5 of 5. |
| Quiet | Its move grade is below normal: a narrow range is priced and the price is not moving. |
| Short gamma | Dealers' net gamma is negative: their hedging goes with a move. |
| Within 1 % of the gamma flip | The close sits right at the level where dealer gamma changes sign. |
| Within 1.5 % of a wall | The close is within 1.5 % of the call wall or the put wall. |
| IV rank 80 or more · 20 or less | 30-day IV in the top fifth / bottom fifth of its own last year. |
| IV below realised | IV minus 20-day realised vol is below zero (options cheap against movement). |
| Option volume 2× average | Contracts traded today at least twice the 20-day average. |
| 3 or more unusual readings | Three or more of the Viewer's readings are beyond 3σ of their own last 60 sessions and among the most extreme 2.5 % of their own year. |

The columns
| Column | How to read it |
|---|---|
| Move | A five-bar grade — Quiet · Normal · A little more · Bigger · Much bigger — of how much movement the options and the price point to, against the ticker's own year. A size, never a direction. |
| Gamma | ▲ long: dealers hedge against a move and calm it · ▼ short: they hedge with it and stretch it · ◆ at the flip. |
| For | Sessions the gamma stance has held. |
| Net GEX | Dollars of stock the dealers trade for a 1 % move. |
| vs flip | The close against the gamma-flip level (+ above it). |
| Call wall · Put wall | The strike with the most call / put open interest, with its distance. "far" = more than a practical distance. |
| Max pain | Front expiry: the price where the options expiring next are worth the least. |
| IV rank | Where today's 30-day IV sits in its one-year range: 0 low, 100 high. Highlighted at 80+ and 20−. |
| IV−HV | Implied minus 20-day realised, in vol points. |
| Exp. move | One standard deviation over 30 days, % of the price. |
| Skew 25Δ · Term | Puts over calls at equal delta · 90-day minus 30-day IV (below zero = the near term is priced as the risky part). |
| Unusual | How many readings sit beyond 3σ of their own last 60 sessions and among the most extreme 2.5 % of their own year; hover for the list. |
| Changed tonight | What is different from the session before. |
The ticker card
Click a row. The card shows the close, the 1-day and 20-day change, the gamma stance, IV and rank, and the move grade, then:
- Changed tonight — each change in a sentence.
- The levels, from the top — call wall, put wall, max pain, gamma flip and the close in one list with the distance of each; levels more than 15 % away are marked "far: no practical pull".
- Why this move grade — the points behind it: a wide priced move (+2), already moving (+2), IV in the top fifth (+1), short gamma (+1), a wide corridor between the walls (+1), or "quiet" (−2).
- Unusual against its own last 60 sessions — the largest readings in σ.
- A button to open it in the Viewer.
Option market A · B · C
How busy a ticker's options are: A · Deep, B · Active, C · Lighter. A thin option market swings by itself, so lists of "unusual" things on Tonight only count A and B.
🎓 Pro tipCombine one state chip with one price chip: "Short gamma" + "Within 1.5 % of a wall" finds tickers where hedging goes with the move and a big level is about to be tested. Then sort by Net GEX.
⚠ The Move grade is a size, not a sideNothing on this page says up or down. Every figure is end-of-day and describes option positioning.
A routine that works
- Start with the market you trade; sort by Unusual or × average.
- Add 1–2 chips that describe your setup.
- Click the top five and read their cards.
- Open the ones that survive in the Options Chart.
- Star the ones you will follow; Tonight then shows only what changed on your list.
