What it adds
Add volatility sensitivity to the chart
Vanna describes how option delta changes as implied volatility changes. The VEX heatmap lays that exposure out by strike and time behind the candles; the Vanna markers put the modeled levels beside price. Each has its own switch, so you can keep either on without touching GEX.
Vanna markers
Modeled Vanna levels for the active ticker, drawn beside price.
Expiration window
The automatic window of 0 to 45 days to expiration, or one expiration you pick in the popup.
Two switches
The VEX heatmap and the Vanna markers come and go on their own, without changing the GEX, DEX or flow layers.
Futures levels
With futures levels on, the Vanna levels of SPX, NDX, RUT and DJX map onto their futures contracts too.
How it works
Three steps
Open the ticker
Open the chart. The extension reads the active symbol every 8 seconds.
Turn on VEX heatmap or Vanna markers
Keep the automatic expiration window or choose one expiration.
Compare with GEX and price
Read vanna beside the walls and the flip instead of on its own.
Know the limit
Vanna estimates depend on the options data and the model. They are research context, never a forecast of the next move.
