Most gamma-exposure tools only cover SPX, SPY and QQQ, and most want your email before showing you a chart. This one runs on any optionable US ticker with no signup: net dealer gamma by strike, the zero-gamma flip level, call wall, put wall, max pain and the options-implied expected move, updated through the session. Dealer positioning is inferred from open interest, not observed. It tells you whether hedging flow is damping moves or amplifying them — not where price is going.
I trade options and got annoyed by the same two things every time I wanted a gamma read: the tools only covered SPX, SPY and QQQ, and the ones that covered more wanted an email before they'd render a chart. So this runs on any optionable US ticker and there's no signup, no trial, no email gate.
What it shows per ticker: net dealer gamma by strike, the zero-gamma flip level, call and put walls, max pain, and the implied expected move.
The part I'd rather say up front than have someone find out: dealer positioning is inferred, not observed. Nobody outside a market maker knows their actual book — every gamma tool, including this one, starts from open interest plus an assumption about who's long and who's short. So it's a regime read (is hedging flow damping moves or amplifying them?) rather than a direction call, and illiquid chains produce garbage that the tool will happily print at you anyway.
Two things I know are weak and am working on: index gamma is harder than single names because of the SPX/SPY/QQQ overlap, and the chain data can lag intraday — it's a snapshot, not a live tape.
If you know the market-making side, I'd genuinely like you to tear up the assumptions in the gamma calc. That's the part I'm least confident about.
