Overview

ThetaForge is the Theta Harvest Overlay — a real-time WebSocket window that distills aggregate time decay into a single headline metric: Total Theta (K/day). It sums the call and put theta values from the live gamma grid and displays the result as thousands of dollars of daily time decay.

While the HTTP-based Theta Decay window provides a per-strike breakdown with charts, ThetaForge provides the aggregate number in real-time — ideal for persistent monitoring and quick reads on whether time decay is accelerating or decelerating across the chain.
