Top Change ScannerTop Change Scanner
The biggest dealer-gamma changes on the board, ranked at the open and graded at the close.
The full live dashboard — every ticker, every tool. $50/month, cancel anytime.
A big gamma wall that has been sitting at a strike for a week is information everyone already has. A wall that appeared this morning is not. The Top Change scanner ranks the option board by how much gamma exposure actually MOVED — the strikes and contracts where dealer positioning changed most since the prior session — and puts the leaders on cards you can read in one pass.
Every card is then tracked, not just published. Snapshots accrue through the cash session and each card can be flipped to its own intraday history, so you watch a change either build on itself or fade. The chart is filtered to regular trading hours on purpose: snapshots are recorded around the clock, but a chart that mixes an illiquid 3am print into the day's shape is a chart that lies about the day.
At the close the scorecard freezes and each pick is graded. Until then it says so — "live · peak so far" — rather than presenting a mid-session number as a final one.
- ✓Ranked by CHANGE in dealer gamma, not by static size
- ✓One card per leader, readable in a single pass
- ✓Per-card intraday history — watch a change build or fade
- ✓Cash-session only: overnight prints never distort the shape
- ✓A scorecard that freezes at the close and grades every pick
- ✓Says "live · peak so far" until it is final — no dressed-up mid-day number

These are the first five rows of thirty-five. The same table carries the C, D and F rows and the three that never went green — the header counts them out loud (avg 57/100, never green 3) precisely so a top-of-board screenshot cannot be mistaken for the whole board. Low % is the worst drawdown before the peak, which is the column that decides whether a +400% print was tradeable.

The line is the contract's own mark through the cash session, so the entry, the peak and everything the position did in between are one picture rather than three numbers in a row.
