Dealer gamma exposure, max pain, open interest, and the full IV surface for an entire options watchlist land in one self-hosted dashboard that keeps every snapshot it collects. Add any US-listed ticker, press Collect data, and a banner above every view states net GEX, call and put walls, the gamma flip, and a plain-language regime label. The GEX heatmap lays out strike by expiry with historical replay, and the Changes tab compares two trading days side by side. A Contract view splits one option's price move into delta, gamma, vega, theta, and an honest residual. The screener lists every contract with seven greeks and range filters, unusual activity flags volume outliers against each contract's own history, and OI Delta ranks the biggest overnight position changes. Collection can run automatically from every 15 minutes to once a day, and it sleeps through closed markets to save disk space. The 3D volatility surface and skew slices show how implied volatility is priced across the chain.
