Sessions of measured history1
Percentile vs. this symbol's own trailing sessions; 20-session warm-up; delayed, observational, not investment advice.
What this is: Flowstradamus measures each session's options activity for SPAL against SPAL's own trailing history — not the market's, not a fixed threshold — so "unusual" means the same thing for a mega-cap and a small name. Most days are ordinary, and we say so. What a print intends — a bet, a hedge, one leg of a spread — is not knowable from the tape, and we don't pretend otherwise.
