Supply and Demand X-ray

What is Supply and Demand X-ray?

Supply and Demand X-ray is a strike chart of Price, Supply, and Demand for one ticker and one expiration. Call contracts sit on the left. Put contracts sit on the right. In The Money is the first band. A Supply bar is not a buy.

A chain lists strikes. Gamma Exposure maps walls. This page is one chart per contract. Yellow is Price. Green is Supply. Red is Demand. The bar under each chart is Supply percent versus Demand percent, plus a Supply count and a Demand count. When Demand sits far above Supply on that bar, Demand is winning that contract. When Supply sits far above Demand, the reverse. Either bar can still be a hedge, a spread, or a dealer book.

Pick Symbol, Expiration, then Go. Rows starts at 12. In The Money, labeled ITM, is the first section. Out Of The Money, labeled OTM, sits under that. A chart title looks like SPY C 767 2026-09-18 (0D). Contract Look-up is a separate tab, not this chart grid. None of those charts is an order.

On EZPZ, the live page title is Supply & Demand X-ray. The active tab is Supply & Demand. The other tab is Contract Look-up. The page starts on SPY. Rows starts at 12. Symbol placeholder is e.g. AAPL. Go loads the ticker and expiration. Option Chain is the listed call and put book for one expiration. This page is Price, Supply, and Demand on each contract, not LAST, VOLUME, and OI. Gamma Exposure is the strike table with Call Wall and Put Wall. Market Maker Exposure is the SPX Flip Level chart with Call Wall, Put Wall, and Expected Move(VEM) and DEM. Market Cross Flow is the SPY, SPXW, and QQQ GEX grid next to candles. Greeks Heatmap is the strike-by-expiration grid with Gravity Magnet Score. Option Depth Flow is the searchable strike-by-time Bubble or Gradient chart. Ticker Explorer is the one-symbol dashboard. Largest Premium By Tickers is the Bullish Flow / Bearish Flow leaderboard. Index Trader is the index dashboard with Premium Traffic Lights. Top 20 Optionable ranks listed-option names by Vol. * Price. Market Wave is the Current Day chart of Net Call Premium versus Net Put Premium. Net Flow Graph is one ticker you search with Filter ticker, plus Cumulative Volume Delta. Historical Net Premium is the 15D Cumulative lookback with a daily table. 0DTE Graph is the same-day premium chart with Filter ticker. The 0DTE dropdown is the lock. Weekly-DTE Graph is the WTE chart of premium that expires by Friday. 7-DTE Graph is the 7DTE chart of premium in the next 7 days. Movers and Shakers Tide is that chart job for about 18 mega-cap names. Money Sentiment is Bought Ratio, Net Sentiment, and Netflow Graph for one ticker. Net Premium Heatmap is the strike-by-expiration grid of Net Premium for one ticker. Live Flow is the tape of prints. Unusual Activity keeps only large, sweep, and block prints.

How Supply and Demand X-ray works on EZPZ

Search Symbol, pick Expiration, leave Rows on 12, then Go. Read Call on the left and Put on the right. Start in In The Money. It is not a combined rating. If a bar looks one-sided, read Price on the same chart. Scroll to Out Of The Money if you want strikes away from spot. Open Contract Look-up only if you want that other tab.

How this differs from Option Chain

Option Chain is the listed calls and puts for one ticker and one expiration, with LAST, VOLUME, and OI on each strike. This page is one Price, Supply, and Demand chart per contract. Use the chain for the book. Use this page for the bars. Use Gamma Exposure when you want Call Wall and Put Wall. 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 Index Trader when you want traffic lights. Use Market Wave when you want Current Day and Historical. Use Net Flow Graph when you want Filter ticker plus Cumulative Volume Delta. Use Historical Net Premium when you want the 15D table. Use 0DTE Graph when you want same-day premium. Use Weekly-DTE Graph when you want Friday. Use 7-DTE Graph when you want the next 7 days. Use Movers and Shakers Tide when you want the 18-name basket. Use Live Flow when you want the prints.

Anatomy of a contract chart

You do not need every contract on every expiration. Use the tabs if you want a map of the fields.
