Compare · Gamma data
GEXBot made its name serving gamma-exposure data to traders who wanted the numbers without the wrapper. I build Sharpnel, so weigh my bias — but the decision between us is genuinely structural, and this page lays it out straight, including the cases where staying put is right.
Sharpnel draws the walls and the flip on the price axis of a native desktop terminal — recomputed through the session for the index books as 0DTE flow rebuilds the surface, nightly for single names — on the same screen as the DOM ladder, footprint, TPO and tape. The wall isn't a number on a dashboard; it's a line the order flow visibly defends or loses.
Quant API serves the computed ladders and history over REST — the same numbers the terminal draws, for the trader who wants them in their own system. You get the whole terminal with it, because a feed you can't eyeball against a chart is hard to trust.
Which chain, which expirations, OI or volume, the positioning assumption, recompute cadence, delivery. Two vendors disagreeing on a wall's price are answering these differently — ask everyone, us included. Our answers are on the public methodology page.
Sharpnel's free ES and NQ levels are graded against the real session every day, misses kept. As of 31 July 2026: 88 wall tests, 28 broke. Publishing the unflattering number is the point — it's what makes the flattering ones believable.
Yes, from two directions. If you want gamma levels to trade with, Sharpnel draws call walls, put walls and the gamma flip on the chart of a full desktop terminal, next to the DOM and footprint. If you want the data itself to build with, Sharpnel's Quant API tier serves the computed gamma ladders and history as a REST feed.
Pro (the terminal, levels on-chart) is $125/month or $1,125 for a year paid once. Quant API (everything in Pro plus the raw computed feed) is $345/month. The free tier publishes today's headline ES and NQ levels every morning with a public grade against the session.
From the option chain, nightly, with the methodology documented publicly — which chain, which expirations, the dealer-positioning assumption, and when it recomputes. The methodology page exists so the numbers can be argued with; a level you can't interrogate is a level you can't trust.
If your workflow is already built around their dashboards or their data shape and it's working, switching costs are real and worth respecting. The case for Sharpnel is consolidation: the levels, the order flow that defends them, and the research desk in one terminal — or one API if you're the builder.
Kick the tires for free: today's graded ES levels, then the terminal on delayed data with no card. Builders can read the API surface on the pricing page.
GEXBot is a trademark of its owner; it's named here for comparison only. Nothing on this page states GEXBot's prices or features — verify theirs with them. Sharpnel's figures are date-stamped and live on the graded-record and methodology pages.
