Compare · Gamma levels
SpotGamma is one of the best-known names in dealer-positioning research, and if you're reading this you're probably deciding who to pay for gamma levels. I build Sharpnel, so read me accordingly — but this page is written to be useful even if you choose them, because the way to choose is the same either way.
A research service delivers levels as a product: dashboards, morning notes, commentary you read alongside whatever platform you trade on. A terminal makes levels a layer: Sharpnel computes the call wall, put wall and gamma flip from the option chain every session and draws them on the price axis of the chart you already trade — recomputed through the session for the index books as 0DTE flow rebuilds the surface, nightly for single names — with the DOM ladder, footprint, TPO and reconstructed tape on the same screen. Whether that difference matters is the whole decision: if the levels live where the order flow lives, you see the defense of a wall as it happens instead of checking a dashboard after.
A native desktop trading terminal (Windows + notarised macOS). Gamma walls on-chart, deep DOM with pull/stack detection, footprint in five modes, TPO, the options suite, and a primary-source stock research desk. Pro is $125/mo or $1,125/yr paid once; a free Explorer tier runs everything on delayed data.
Research depth and written commentary are real value if reading is your workflow. No terminal replaces an analyst's note you like. The honest question is whether you want levels delivered as content to read, or drawn as a layer on the chart you trade.
Which option chain feeds the computation; which expirations count; open interest or volume; the dealer-positioning assumption; how often levels recompute; and how they're delivered. Ask these of anyone — the answers explain why two vendors' walls sit at different prices on the same day.
Where is the published, graded record? Sharpnel grades its own free ES and NQ levels against the real session daily and keeps the misses up. As of 31 July 2026: 88 wall tests, 28 broke. About a third — because that's what a wall is. Any provider unwilling to publish that number is asking you to take their word.
For the dealer-positioning core, yes: Sharpnel computes call walls, put walls and the gamma flip nightly and draws them on the price axis of a full trading terminal — next to the DOM, footprint, TPO and tape. SpotGamma is a well-known research service built around dashboards and commentary; Sharpnel is a desktop terminal where the levels live on the chart you actually trade.
Sharpnel Pro is $125/month (or $1,125 for a year, paid once) and includes the terminal itself: gamma levels on-chart, the DOM ladder, footprint, TPO, the options suite and the stock research desk. Most traders assembling levels + orderflow + research separately pay several subscriptions to get there.
Ask one question first: where is the published, graded record? Sharpnel grades its own free ES and NQ levels against the real session every day and keeps the misses public. As of 31 July 2026 the running wall record stood at 88 tests with 28 breaks — roughly a third — which is what a wall honestly is: a level that usually holds, not a promise.
If what you want is written market commentary and research to read away from the charts, a research-first service is a reasonable fit. Sharpnel is built for the trader who wants the levels ON the chart, inside the terminal they trade from, with the order flow that has to defend those levels visible next to them.
The cheapest way to decide: read today's free graded ES levels, then put the terminal on your screen with the free tier and see the walls on your own chart.
SpotGamma is a trademark of its owner; it's named here for comparison only. Figures about Sharpnel's record are date-stamped and live at the graded-record page; nothing on this page states SpotGamma's prices or features — check theirs with them.
