Illustration. The live dashboard shows collected, 15-minute-delayed data and never fills in missing snapshots.

What you see

Structure, migration and price in one frame.

No switching between a gamma chart and a price chart. Every view is centred on SPY and built from real options-chain snapshots.

Gamma Wall

Where gamma sits now

The latest snapshot across 30 strikes around SPY, with positive and negative gamma ranked by strength.

Migration

Where the dominant level moves

A column every 15 minutes. The strongest |GEX| strike of each snapshot is lit blue, so shifts are easy to follow.

SPY overlay

How price trades through it

The 5-minute SPY path drawn directly over both views, with a beacon on the latest price.

Key levels

Call wall and put wall

The strikes with the largest positive and negative gamma, updated with every snapshot.

A trading day

The dashboard builds as the session unfolds.

All times Eastern. Holidays and early closes follow the NYSE calendar.

Previous session

Yesterday's completed session, clearly dated, while today waits for data.

First snapshot

The first gamma column and the SPY path from the open (data is about 15 minutes delayed).

Live build-up

A new gamma column every 15 minutes and SPY every 5. Missed snapshots stay visibly blank.

Session complete

The final snapshot closes the day, which becomes tomorrow's previous session.
