Net Premium Heatmap
Strike-by-expiration Net Premium for one ticker, with Daily Heatmap and Weekly Heatmap.
What is a net premium heatmap?
A net premium heatmap is a strike-by-expiration grid of net call versus put premium for one ticker. Rows are strikes. Columns are expiry dates. Green cells are positive Net Premium. Red cells are negative. Daily Heatmap is the default. A bright cell is a lean, not a buy.
A tape shows prints. Net Flow Graph shows a session line. This page is a table. How to Use says Net Premium is the net flow of money into calls versus puts. A positive value is labeled bullish sentiment. A negative value is labeled bearish sentiment. Strikes are the price levels on the left. Expiry Dates sit across the top. The current-price row is highlighted. Either color can still be a hedge, a spread, or a dealer book.
Daily Heatmap cells show a dollar amount. When a percent change is present, it sits under that number with an up or down marker. Weekly Heatmap cells show the dollar amount only. How to Use also names Same-day expiration (0DTE), Weekly expiration, and Monthly expiration (OPEX) as time frames on the grid, not as orders. None of those cells is a trade.

How Net Premium Heatmap works on EZPZ
Search a ticker, leave Daily Heatmap on, then read the highlighted strike first. It is not a combined rating. If a cell looks loud, read the same strike across expirations, then the same expiry down the strikes. Open Weekly Heatmap if you want that other grid. Open How to Use if you want the in-page glossary for Net Premium, Strikes, and Expiry Dates.
How this differs from Historical Net Premium
Historical Net Premium is a multi-day lookback of net call versus put premium with Cumulative and a daily table. This page is one ticker mapped by strike and expiration. Use Historical Net Premium when you want 5D, 15D, or 30D. Use this page when you want which strike and which expiry hold the premium. Use Gamma Exposure when you want Call Wall and Put Wall. Use Money Sentiment when you want Bought Ratio and Net Sentiment bars. Use Net Flow Graph when you want Filter ticker plus Cumulative Volume Delta. Use Market Wave when you want Current Day and Historical. Use Movers and Shakers Tide when you want the 18-name basket. Use 0DTE Graph when you want same-day premium as a session chart. Use Weekly-DTE Graph when you want Friday. Use 7-DTE Graph when you want the next 7 days. Use Supply and Demand X-ray when you want Price, Supply, and Demand on each contract. Use Index Trader when you want traffic lights. Use Ticker Explorer when you want quote, PCR, GEX charts, and unusual activity. Use Largest Premium By Tickers when you still need a name. Use Top 20 Optionable when you want Vol. * Price rank. Use Live Flow when you want the prints.
Anatomy of the grid
You do not need every cell on every ticker. Use the tabs if you want a map of the fields.
The card title is Daily Net Premium Heatmap. Daily Heatmap is the selected tab.
| Field | What you are looking at |
|---|---|
| Strike | The left column. How to Use calls these the price levels where options activity is concentrated. |
| Expiry Dates | The top row of dates. How to Use lists same-day, weekly, and monthly as time frames. |
| Net Premium | The dollar in each cell. Green is positive. Red is negative. How to Use reads positive as bullish and negative as bearish. |
| Percent change | When it is present, an up or down marker and a percent sit under the dollar amount. Zero or missing change is omitted. |
The other tab is Weekly Heatmap. The card title is Weekly Net Premium Heatmap.
| Field | What you are looking at |
|---|---|
| Strike | The same left column of price levels. |
| Expiry Dates | The same date columns across the top. |
| Net Premium | The dollar in each cell. Weekly Heatmap does not print the percent-change line under the dollar. |
How to Use opens the in-page guide. It is a glossary, not a signal list.
| Label | What the guide says |
|---|---|
| Net Premium | Net flow of money into calls versus puts. |
| Strikes | Price levels where significant options activity is concentrated. |
| Expiry Dates | The time frame of the bets on that column. |

How people actually use it
Start on Daily Heatmap
Leave SPY on, or search a ticker you already care about. Read the highlighted strike across expirations first. You are watching a grid, not picking a contract yet.
Compare a loud cell to its row
If one expiry is much greener or redder than the rest of that strike, check neighboring strikes on the same date. A lonely cell is a prompt, not a fade.
Switch to Weekly Heatmap
Use Weekly Heatmap when you want the weekly grid for the same ticker. Strikes and Expirations stay where you left them. The percent-change line is not on this tab.
Use it next to the other tools
This page is the strike-by-expiry map. Open Gamma Exposure for walls. Open Live Flow if a cell makes you want the prints.
