SIGNUM HQ

Market-structure data that normally lives inside a professional terminal, on your phone, free. Dark pool share, max pain, gamma exposure and the dealer gamma flip, call wall, unusual sweeps, IV skew — per ticker, every US session. Guardian compresses momentum, participation and price trend into one risk reading. Ten US sectors get an AI brief after each close. English, Korean, Japanese. iOS and Android. No account, no paywall. Information and education only — not investment advice.
