What this is: Flowstradamus measures each session's options activity for TSM against TSM'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. This view measures contract-level activity using session volume and a reference price. It does not establish whether that activity represented a directional position, a hedge, or part of a spread.
