Premium Heat Grid dashboard
The Premium Heat Grid maps call and put premium, gamma exposure and vanna exposure across strike and expiry. It turns a long option chain into a visual concentration map, helping researchers see whether activity clusters near spot, on one expiry or across several maturities.

What the premium heat grid dashboard shows
A heat grid is useful because concentration is difficult to see in a conventional chain table. The same data becomes easier to compare across calls, puts, strikes and expiries when magnitude is encoded consistently in a two-dimensional layout.
The screenshot above is from the working product, not a mockup. The visible controls and fields are the same ones trial and Pro users research with; only the market-data timing changes between the two access levels.
- Call-side and put-side cells arranged by strike and expiration.
- Premium mode for where money changed hands.
- GEX mode for estimated gamma exposure around each strike.
- VEX mode for estimated sensitivity to volatility changes.
How to read this dashboard
Read the dashboard as one step in a sequence. Record what it directly shows first, then use the next view to test the interpretation rather than turning a color or ranking into a conclusion.
- Locate the underlying price and identify the nearest strike cluster.
- Compare calls and puts within the same expiry before comparing maturities.
- Switch from premium to GEX or VEX to separate traded money from exposure mechanics.
- Open the open-interest view to see whether fresh activity sits on existing positions.
What this view cannot establish
A bright cell shows concentration, not intent. Large premium may belong to one leg of a spread, and exposure estimates depend on pricing inputs that change through the session.

Questions people ask about this
What is an options premium heatmap?
It is a visual matrix that groups premium or derived exposure by strike and expiry. Stronger cells indicate larger values, making concentration easier to see than in a row-by-row chain.
Does the heat grid include 0DTE options?
Yes. The expiry axis can begin with same-day contracts and continue through later cycles, allowing 0DTE concentration to be compared with longer-dated activity.
Is a high-premium strike support or resistance?
Not by itself. Premium concentration needs direction, open interest, dealer-exposure estimates, price behavior and time to expiration before it can support a market-structure hypothesis.
