It started with a question nobody could answer cleanly.
Where is dealer gamma actually sitting — and why does price keep pinning, then ripping, around levels the charts never show? The tools that claimed to answer it were closed, overpriced, and data-poor. The "GEX" numbers floating around were black boxes or plainly wrong. So we built our own.
1 · The reasoning
Dealer gamma is the quiet force behind expiry pinning, squeezes and regime shifts. Map where it concentrates — call wall, put wall, the zero-gamma flip — and the tape stops looking random. That map didn't exist the way we wanted it, so it became the whole project.
2 · The learning curve
We climbed it the hard way: the options-gamma math, zero-gamma sign-flips and volatility triggers, max-pain as a weak secondary force, and the tricky part — translating index and ETF option gamma onto the futures traders truly watch.
3 · Designing & implementing
Real engineering, not a spreadsheet. Live data pipelines, an engine that recomputes levels continuously, a terminal to draw them, and a daily card engine that publishes the read in plain language.
4 · Research & debugging
The unglamorous months. Reconciling feeds, auditing every calculation line by line, forward-testing honestly instead of curve-fitting, and rebuilding whatever didn't survive scrutiny. We trust the engine because we broke it ourselves first.
