Where the open interest and liquidity actually sit on a chain, mapped so you can see the walls that shape the underlying.
A bubble-chart view of an entire options chain: expiration on the X-axis, strike on the Y-axis, bubble size = volume, color = liquidity score / spread / OI / volume. A 0–100 Tradability Score (Excellent → Poor) tells you at a glance whether a ticker's options are liquid enough to trade.
When to use it
Use the Liquidity Map to pick strikes that fill without giving up edge. Before entering a spread or multi-leg structure, check the Liquidity Map to confirm sufficient open interest and tight spreads at your target strikes. An illiquid options chain makes it difficult to get filled at a fair price and expensive to exit.
