StrikeGEX vs SpotGamma: Which Dealer-Gamma Tool for 0DTE?
Pricing and features verified from each vendor's own site as of July 11, 2026. Competitor pricing moves — check the source links before relying on a number.
SpotGamma is one of the most recognized names in retail dealer-gamma analytics — years of published research, twice-daily notes, and an institutional tier. StrikeGEX takes the opposite bet: instead of research breadth, it puts everything into the 0DTE index session — a proprietary server-side engine that computes the gamma surface, names the levels on a heatmap you can read in one glance, and grades its own daily call against the close in public. For an intraday SPX trader, that difference in shape matters more than the difference in brand age.

Quick Comparison
SpotGamma tiers
Standard $89/mo, Essential $99/mo, Pro $129/mo, Alpha $299/mo (includes HIRO), Institutional from $1,999/mo. Each monthly tier has a discounted first month, and annual billing is cheaper — Alpha, for example, works out to ~$224/mo billed annually.
Where SpotGamma Fits Better
- HIRO. SpotGamma's real-time options-flow indicator is a distinctive tool for watching live dealer hedging pressure, bundled starting at the Alpha tier ($299/mo). StrikeGEX reads the live tape through positioning — wall momentum and the Commander verdict — rather than a flow tape; if a flow-first signal is specifically what you want, HIRO is the draw.
- Written research. Twice-daily Founder's Notes across every plan. If daily written market commentary is a core part of your process, that's SpotGamma's strength.
- Breadth beyond the index session. Equity Hub covers thousands of stocks and ETFs — useful for swing trades on single names outside StrikeMap's 304-symbol universe.
Where StrikeGEX Wins
- The realistic price comparison favors us. The SpotGamma feature intraday traders actually want — HIRO — only unlocks at Alpha ($299/mo). So the true head-to-head for a 0DTE trader is $249 (StrikeGEX, everything included) vs $299 (SpotGamma Alpha). StrikeGEX is cheaper for the comparable job.
- The interpretation is done for you. SpotGamma gives you levels plus notes to synthesize. StrikeGEX's proprietary server-side engine commits to a named King Node, walls, air pockets, and a live Commander verdict on who controls the tape. You get a decision-ready read, not homework.
- Levels you see, not levels you look up. StrikeGEX renders the gamma surface as a heatmap where the level that matters visually dominates the strike — no cross-referencing a note against your chart mid-session. StrikeChart puts GEX directly on the candles.
- Public daily grading. StrikeGEX publishes its King Node call and grades it against the real close every trading day, in public, before you subscribe. Research commentary can't be graded; a named daily call can — and ours is.
Bottom Line
SpotGamma earned its reputation on research breadth, and if you want HIRO plus written notes across thousands of equities, it's a fair pick at Alpha. But if your trading day is the 0DTE index session, StrikeGEX is the tool actually shaped like your job: an AI-computed map you read in one glance, a named daily level instead of commentary to interpret, and — unique in this matchup — a public daily grade proving whether the call was right. At $249 versus $299 for the comparable tier, the focused tool is also the cheaper one. Check the track record, then let the trial settle it.
FAQ
- Is StrikeGEX cheaper than SpotGamma?
- For the comparable tier, yes. StrikeGEX Pro ($249/mo, everything included) undercuts SpotGamma's Alpha plan ($299/mo — the tier that includes HIRO). SpotGamma's lower tiers ($89–$129/mo) cost less but don't include HIRO, the feature most intraday traders are buying it for.
- Does StrikeGEX have anything like HIRO?
- A different mechanism for the same question. HIRO reads live options flow; StrikeGEX reads live positioning — wall momentum on the heatmap plus the Commander AI verdict on who controls the tape and where it flips. Positioning-based rather than flow-based, and included in the one plan rather than gated behind the top tier.
- Which is better for 0DTE SPX trading specifically?
- SpotGamma covers 0DTE inside a much broader equity/index toolkit. StrikeGEX is purpose-built around 0DTE SPX/SPY/QQQ/IWM — the morning map, the named level, the live verdict, and the graded recap — with nothing else competing for the product's attention.
- Does SpotGamma publish accuracy grading like StrikeGEX's King Node?
- SpotGamma publishes twice-daily Founder's Notes and market commentary, but does not run a public day-by-day graded scorecard of a specific level call. StrikeGEX grades its King Node against the actual close every trading day, in public.
- What's the cheapest way to try each?
- StrikeGEX: $69 for 14 days of full access (or a 7-day Whop trial). SpotGamma: the Standard plan discounted to $17 for the first month, then $89/mo — without HIRO. To trial the HIRO tier you're at $49 for the first month, then $299/mo.
