📊 Multi Heatmap

Compare launches with four default tickers: SPX, SPY, QQQ, and IWM. These give you an instant snapshot of the broad market's GEX landscape across large-cap, tech-heavy, and small-cap indices.

You can replace any of these with your own tickers to compare any combination of US stocks and ETFs.

• Add a ticker — Type a symbol in the input field at the top of the Compare view and press Enter or click the add button. The ticker is fetched and a new card appears in the grid.
• Remove a ticker — Click the ✕ button on any ticker card to remove it from the comparison.
• There's no hard limit on the number of tickers, but performance is best with 4–8 tickers.

Every ticker card in the Compare view displays a condensed GEX profile:

• Ticker & spot price — Current price with change percentage.
• King Strike — The primary GEX node with distance from current price.
• Gamma Flip — The price where net GEX transitions from positive to negative.
• Net GEX bar — Visual bar showing the total GEX direction and magnitude.
• Summary metrics — GEX Ratio, Net GEX, P/C OI, and other key indicators in compact badge format.
• Strike profile — A mini GEX-by-strike bar chart showing the distribution of gamma across price levels.

Toggle between two layout modes:

• Horizontal — Cards arranged side by side in a row. Good for comparing 2–4 tickers on a wide screen.
• Vertical — Cards stacked vertically. Good for more tickers or narrower screens.

Compare supports auto-refresh with configurable intervals — from every 15 seconds to every 15 minutes. A countdown timer shows when the next refresh will occur. All tickers refresh simultaneously.

Each card shows a data age indicator — how many seconds since the last successful fetch. If data becomes stale (e.g., network issue), the age turns red to alert you.

• Index comparison — SPY vs QQQ vs IWM: are all three in positive or negative GEX? Is one index diverging?
• Sector rotation — Compare sector ETFs (XLF, XLE, XLK) to see where gamma is concentrated across sectors.
• Relative positioning — Compare two or more individual stocks to see which has the King Strike closest to its current price, which has the highest GEX Ratio, etc.
• Pre-earnings scan — Compare tickers reporting earnings this week to observe their GEX profiles before the event.
