The thing no one explained you

Why dealer positioning moves SPY

Every options contract you trade has a counterparty: a market-maker who has to stay flat. When SPY rises into a strike where they sold a lot of calls, dealers sell stock to hedge. When SPY falls into a strike where they sold a lot of puts, dealers buy stock to hedge.

Those flows aren't optional — they're math. Multiply that math across millions of options open interest, and you get real price walls. The biggest ones — the Call Wall (where dealer selling caps rallies) and the Put Wall (where dealer buying floors drops) — show you exactly where this week's tape is structurally pinned.

Knowing them before the open changes how you size, where you hedge, and which moves to fade vs follow.

Common questions

What people ask before signing up

Is this trading advice?

No. The Weekly Snapshot is a structural read of where dealers are positioned — it tells you where price is likely to find friction or support, not what to buy or sell. Always do your own research and consult a financial advisor before trading.

How is the data calculated?

We compute gamma exposure from the open interest on SPY options expiring in the next 5 trading days. The Call Wall is the strike with the largest positive call gamma, the Put Wall is the strike with the largest negative put gamma. The methodology mirrors what institutional desks track internally — we just put it in plain English for retail.

Will I get spammed?

One email per week. Mondays at 7:30 AM ET. Sometimes a major product update — but those are rare and we keep them short. Every email has a one-click unsubscribe.

Why is it free?

We hope a fraction of subscribers love it enough to upgrade for live data, all 30 tickers, and the full GEX Radar dashboard. The rest get a useful Monday read for free, forever. We'd rather earn paid users by delivering value than lock everything behind a paywall.

What if SPY isn't my main thing?

The Weekly Snapshot is SPY-only because SPY is the index everyone watches and most trades are correlated to it. If you trade single names (NVDA, TSLA, etc.) you'll want the live dashboard — but the SPY read still gives you a baseline regime read for the whole tape.

Is GEXBoard new?

We're in beta — the platform launched April 2026 with founding subscribers locked at $19/$39/$79 forever. The Weekly Snapshot stays free regardless.

About

Built by retail, for retail.

GEXBoard exists because the gamma map institutional desks read every morning was hidden behind $30K Bloomberg terminals and $500/mo data feeds. We thought retail traders deserved the same structural lens.

We pull live options data, compute dealer positioning, and surface the levels that actually matter — Call Walls, Put Walls, Gamma Flip, dealer regime — for SPY plus 29 other tickers. The dashboard updates in real-time during market hours; the Weekly Snapshot email is the free taste of what's inside.

We're a small team in beta. We don't have testimonial farms or growth-hacked landing pages. What we have is the actual data, transparently computed, sent to your inbox every Monday before the bell. That's the deal.
