How it works
Why the levels hold. Or break.
-
01
Dealers take the other side
Market makers sell the options traders buy, and hedge the delta with stock.
-
02
The hedge is mechanical
Gamma, vanna and charm set how much they buy or sell as price, volatility and time move.
-
03
We map it by strike
Gamma 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.
One terminal. Every view.
The same dealer read, seen from the angle the trade needs.
Flow tape
Institutional options flow from Unusual Whales, including SPX and SPXW, with sweep, batch and side filters.

Touch alerts

FAQ
Questions? Answers.
What is dealer positioning?
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.
What happens after my 7-day trial?
Nothing, if you cancel first. Retail and Whale collect a card at checkout; your trial runs free for 7 days, then the subscription begins automatically at the listed price unless you cancel before day 7.
Can I cancel anytime?
Yes. Start it from your Account page and finish it on Whop, which handles billing. Access continues until the end of the period you already paid for.
Where does the data come from?
Options chains and quotes from derived market data; institutional flow, dark pool prints and earnings data from Unusual Whales.
Do I need a card to start?
Free needs no card. Retail and Whale collect a card at checkout, but nothing is charged for 7 days — cancel before day 7 and you are never billed.
Which tickers are covered?
Free is SPY only. Retail adds QQQ, IWM and the mega-caps, ten tickers in all. Whale has no symbol restriction.
