Frequently Asked Questions

What is gamma exposure (GEX)?+
Gamma exposure (GEX) measures the total gamma that options market makers hold at each strike price. High positive gamma means dealers typically buy dips and sell rallies, which can dampen volatility. Negative gamma means dealers may amplify moves, potentially increasing volatility. VannaCharm calculates and visualizes GEX in real-time across all expirations.
What is vanna exposure (VEX)?+
Vanna exposure (VEX) measures how dealer delta hedging changes as implied volatility moves. When vanna is large and positive, a drop in IV can lead dealers to buy shares, which may contribute to upward price pressure. VannaCharm tracks vanna exposure at every strike and expiration to help you monitor these flows.
What is charm exposure (CEX)?+
Charm (or delta decay) measures how delta changes as time passes. As options approach expiration, charm flows accelerate — dealers must adjust their hedges even if the underlying price doesn't move. VannaCharm visualizes charm exposure so you can see where time-decay-driven hedging pressure is building.
How does dealer positioning affect stock prices?+
Market makers hedge the options they sell by buying or selling shares of the underlying. When aggregate dealer gamma is positive, their hedging activity typically dampens volatility (they buy dips, sell rallies). When gamma is negative, their hedging can amplify moves. Understanding this positioning can help contextualize intraday price action.
What symbols does VannaCharm support?+
The free tier includes IWM and DIA. Starter plans cover 20+ major symbols including SPY, QQQ, IWM, and DIA. Premium plans support 5000+ optionable symbols with real-time broker streaming via Tradier or TradeStation.
Do I need a broker account to use VannaCharm?+
No — the pre-market dashboard works without a broker connection and shows exposure data from the most recent options chain snapshot. For real-time live streaming during market hours, you can connect your Tradier or TradeStation account via secure OAuth.
