Three lenses—not three TikTok synonyms

GEX / Gamma focus

Discusses pinning, migrating walls, how hedging footprints concentrate around strikes.

Vanna spotlight

Measures how changes in implied volatility reshape deltas—second-order bridging between volatility shocks and repositioning overlays.

Charm spotlight

Measures how deltas decay or drift purely from calendar progression toward expiry—a frequent late-session conversational hook (still beware monocausal endings).

Together they articulate pricing + overlays + tenor interactions—beyond guessing direction alone.

FAQ

Does charm equal a deterministic timetable?

No—it models drift tendencies; jump risk still dominates whenever macro headlines intrude.
