Output PreviewBar chart: theta exposure by expiry with acceleration overlay

◧

Fetches real data from the Cayo Largo API

What You'll See

Shows total theta exposure per expiry with acceleration metrics. When theta acceleration turns sharply negative in the last 48 hours before expiry, gamma effects dominate and the theoretical "time decay" becomes unreliable.

The Trading Edge

What most people do

Calculate theta for individual positions. Never look at aggregate theta across an expiry or across the entire surface. Missing the forest for the trees.

What this gives you

Total theta exposure in USD per expiry, theta acceleration (is decay speeding up or slowing down), and urgency zone classification. When theta acceleration spikes for a large expiry, market makers are about to rebalance hard.

Go deeper

Combine with Expiry Ladder to see which expiries carry the most theta weight. Use with Gamma Pinning Map to see if the high-theta expiry is also the most pinned.
