Key Exposure Levels API

What Are Key Exposure Levels?

Key Levels extracts the most important price levels from the options exposure landscape. The gamma flip marks where net dealer gamma switches sign — often a major pivot. The call wall is the strike with the highest positive gamma, acting as resistance. The put wall is the strike with the highest negative gamma, acting as support. Highest OI strike and 0DTE magnet round out the picture, showing where open interest and same-day expiration flows are concentrated.

Common Use Cases

• Define trading ranges — call wall as resistance, put wall as support, gamma flip as pivot
• Set stop losses — place stops beyond key levels where dealer hedging pressure changes direction
• Identify 0DTE magnets — pinpoint where same-day expiration activity is pulling the price
• Alert on level breaks — trigger notifications when the underlying breaches the gamma flip or call/put walls
• Overlay on charts — plot these levels on price charts for visual support/resistance reference

When to Use This Endpoint

Use the Levels endpoint when you need actionable price levels without processing the full strike-by-strike data. For the complete GEX distribution, use the GEX endpoint. Levels is ideal for chart overlays, alert systems, and quick pre-market checks.
