Reading the vol heatmap

When you're looking for premium-selling opportunities, checking tickers one by one is inefficient. A volatility heatmap solves that, it gives you an instant visual overview of IV rank across an entire universe of stocks, so you can identify where options are expensive or cheap at a glance, in seconds.

What the vol heatmap shows

Each cell in the heatmap represents a ticker. The color reflects its current IV rank:

• Red / orange: High IV rank, options are expensive, premium-selling opportunity
• Grey / neutral: Mid-range IV, no strong edge from volatility alone
• Green / blue: Low IV rank, options are cheap, potential buying opportunity

Instead of opening 50 individual options chains, you scan one screen and immediately see where elevated IV is clustering, by sector, by market cap, or across your full watchlist.

How Stryke's Options Screener replaces a heatmap

Stryke's Options Screener gives you the same information in a more actionable format. Rather than a visual grid, you get a sortable, filterable table showing IV rank, IV percentile, volume, open interest, and bid-ask spread for every ticker in your universe, all in one view.

The workflow on Stryke:

Step 1, Sort by IV rank Click IV rank to sort descending. The tickers at the top are your highest-IV candidates, the ones where options are most expensive relative to their own history.

Step 2, Filter by liquidity Add a minimum open interest or volume filter. High IV on an illiquid ticker is a trap, wide spreads will eat your edge before you even get in.

Step 3, Check for catalysts Cross-reference the top candidates with the Earnings Calendar. If a ticker has high IV rank because earnings are in 3 days, that's expected. The most attractive setups are high IV rank with no obvious near-term catalyst, the market is pricing in uncertainty that may not materialize.

Step 4, Identify sector clusters If multiple tickers in the same sector show high IV rank simultaneously, a sector-wide catalyst is likely. This is actually valuable, it means you can spread trades across correlated names without concentrating in a single stock.

What to do with what you find

Once you've identified a high IV rank candidate through the screener, the heatmap logic tells you the trade direction: sell premium. The specific structure depends on your outlook:

• Neutral on the stock: Iron condor or short strangle
• Mildly bullish: Bull put spread or cash-secured put
• Mildly bearish: Bear call spread
• Own the stock: Covered call

IV rank alone doesn't determine the strike or expiration, but it determines whether selling premium is statistically favorable at all. Above 50, the edge is on the seller's side. Below 30, it isn't.

The outlier signal

The most valuable pattern to look for in any IV rank screener is the outlier: a single ticker showing very high IV rank while the rest of its sector is calm. This means the elevated volatility is stock-specific, not a broad sector move that's lifting all boats.

Stock-specific IV spikes without a known catalyst are often the cleanest premium-selling opportunities. The market is overpricing uncertainty on one name. If you can't find a clear reason for the spike, there may not be one, and IV is likely to revert.

Practical checklist

Before entering any trade discovered through IV rank screening:

• IV rank above 50 ✓
• Open interest above 500 at your target strike ✓
• Bid-ask spread under 10% of the option price ✓
• No earnings or FOMC within the expiration window ✓
• Clear technical level supporting your strike placement ✓

All five checked, that's a trade worth sizing.
