SpotGamma

Start with the public SPX Gamma Exposure chart if you want to understand the approach. Its curve uses assumptions about dealer positions to estimate how hedging could amplify or dampen price movement. It is updated daily and is not a direct forecast of the next market direction.

Working with HIRO

HIRO, the Hedging Impact of Real-time Options indicator, belongs to the Alpha subscription. Search for a ticker, then compare price with the estimated options-hedging series. Total combines calls and puts; Put/Call separates them. Next Expiry narrows attention to the nearest-expiring contracts, which may expire today, on Friday or at another scheduled date.

Settings changes the rolling window, date range and displayed alerts. Use Add Tab for frequently viewed tickers, or open Indicators to place a moving average on price or on the HIRO series itself. Check which series you selected before interpreting the overlay. Flow alerts flag activity worth examining; the underlying estimate still depends on the model’s assumptions.

Subscription and account details

The standard monthly checkout forms display these amounts before any coupon:

Registration requests an email, password and payment method, with card or PayPal options. Subscriptions renew automatically. Cancellation is available through the Customer Portal or the published support email. Check the selected checkout’s total and renewal terms when using a promotional link. The separate Opening Setup email offer is free for one week without a card; the public gamma chart remains a separate research resource.
