GAMMA · VANNA · CHARM — BY STRIKE, LIVE
Every session leaves zones where size stepped in. GexTweak marks them as they form, shows the dealer exposure holding them up — gamma, vanna and charm, by strike — and grades every one against what price did next.

How it works
Market makers sell the options traders buy, and hedge the delta with stock.
Gamma, vanna and charm set how much they buy or sell as price, volatility and time move.
Exposure by strike and expiration from the live chain, so the walls and the gamma flip land on the chart where price will meet them.
The same dealer read, seen from the angle the trade needs.

Institutional options flow from Unusual Whales, with sweep, batch and side filters.

Opening-flow positioning in six views, from strike rails to time-of-day.

Earnings calendar with expected move and implied-vs-realized richness.

Probability-of-touch alerts on the levels dealers defend.
The Chart view puts dealer exposure on price: the GEX matrix by strike and expiration sits beside price, and the levels that matter are marked where they are.

The Heatmap shows strike × expiration exposure for GEX, DEX, VEX and CHEX, with a Δ DAY mode that shows what changed since the open.

Surge scans 0DTE contracts and fires signals with an alert stack, quality gates and graded outcomes, so every signal is scored against what actually happened.

SCORE ranks contracts within the day's 0DTE scan. It is not a return.
The Positioning ledger clusters opening options flow by ticker, with premium, confirmed prints and a target zone — six views, from strike rails to time-of-day.

FAQ
When traders buy options, market makers sell them and hedge the delta with stock. Gamma, vanna and charm decide how that hedge changes as price, volatility and time move. GexTweak computes that exposure by strike from the live chain, so you can see where the hedging concentrates.
