StrikeGEX vs Gamma Sonar: Two $249 Gamma Tools, Different Jobs

Pricing and features verified from each vendor's own site as of July 18, 2026. Competitor pricing moves — check the source links before relying on a number.

Gamma Sonar and StrikeGEX land at exactly the same sticker price — $249/month, one plan — which makes this the cleanest apples-to-apples matchup on this site. Gamma Sonar spends the $249 on quantity: 16+ tools, five proprietary signals, 103 tickers, a 60-second recompute. StrikeGEX spends it on the answer: an AI engine that computes the gamma surface with a same-day-weighted model, a heatmap where the level jumps off the screen, a named King Node, a live Commander verdict — and the one thing no toolkit can retrofit, a public daily grade of its own call.

We build StrikeGEX, so read our side knowing that — and check us. Every price and feature claim below comes from each vendor's own pages, dated above, and our daily accuracy grades are public before you ever pay.

Expiration range	0DTE-first (SPX/SPY/QQQ/IWM core), same-day-weighted model	0DTE through LEAPS
Public accuracy grading	Yes — King Node graded vs the close daily	Not published as a graded daily scorecard

Where Gamma Sonar Fits Better

Signal variety. Sixteen-plus tools and five proprietary signals (SSS, FPI, REGD, GVWAP, Hedging Velocity) — a wide bench if you want more inputs to synthesize into your own read.
Full expiration range as a first-class feature. Same-day through LEAPS across all 103 tickers, useful if your gamma work extends well beyond the front expiry.
Free trial. Seven days, no charge, versus StrikeGEX's paid $69 two-week trial.

Where StrikeGEX Wins

An answer beats another input. Five more proprietary signals means five more things to weigh at 9:31. StrikeGEX's AI engine does the weighing: it computes the surface — weighting live same-day positioning rather than a stale open-interest snapshot — and commits to one King Node, walls and air pockets around it, and a live Commander verdict on who controls the tape. Same $249; one buys you a workbench, the other buys you the work.
Public daily grading — the structural difference. A toolkit of signals can't be graded; a named daily call can. StrikeGEX grades its King Node against the actual close, in public, every trading day — a checkable track record at /recaps before you pay. No signal suite offers that, because it structurally can't.
Built to be read at a glance. The heatmap makes the level that matters visually dominate the strike — labeled on the map, momentum on the walls, GEX on the candles via StrikeChart. Sixteen tools means sixteen tabs; one map means one look.
Nearly 3x the symbol coverage. 304 symbols via StrikeMap versus 103 tickers, at the identical price.

Bottom Line

Same price, opposite philosophies. Gamma Sonar is for the trader who wants the widest workbench and enjoys synthesizing signals into their own view — a legitimate preference, and the free week makes it easy to sample. StrikeGEX is for the trader who wants the synthesis done: an AI-computed map read in one glance, a named level, a live verdict, and a public grade every single day proving whether the call was right. When two products cost exactly the same, the one that shows you its scorecard before you pay is making the stronger claim — and we're the only one of the two making it. Run both trials against the same tape and let the grades talk.

FAQ

Do Gamma Sonar and StrikeGEX cost the same?: Effectively yes — both run $249/month on a single all-inclusive plan. StrikeGEX also offers an annual plan at $1,990/year; Gamma Sonar is month-to-month with a free 7-day trial versus StrikeGEX's paid $69, 14-day trial.
What's the main difference between Gamma Sonar and StrikeGEX?: Toolkit versus verdict. Gamma Sonar gives you 16+ tools and five proprietary signals to build your own read. StrikeGEX's AI engine computes the surface with a 0DTE-weighted model, publishes named levels — King Node, walls, air pockets — plus a live Commander verdict, and grades its daily call publicly against the close.
Which covers more tickers?: StrikeGEX — 304 symbols via StrikeMap versus Gamma Sonar's 103 tickers, at the same price. Both cover the major indices and heavily traded names; the gap is in the long tail of single stocks.
Does Gamma Sonar publish a graded track record?: Not in the form of a daily graded call — it publishes tools and signals rather than one specific daily level, so there's nothing to grade. StrikeGEX publishes its King Node call every trading day and grades it against the actual close in public.
Which is better for 0DTE SPX trading?: Gamma Sonar offers signal variety across all expirations. StrikeGEX offers a session-shaped workflow built specifically for the same-day index trade — a 0DTE-weighted surface, morning level call, live Commander verdict, and graded recap. If 0DTE is your session, the tool shaped like your session is the natural pick; the trials exist to settle it on your own tape.
