Greek Flow Line

The cumulative net delta, gamma or vega customers have pushed onto dealers. Watch the slope: a flat line through a big price move is a divergence.

Typing it

FLOWLINESymboldelta|gamma|vega
>FLOWLINESPX gamma
Shows the cumulative net gamma customers have bought in SPX options.

What you see

  • Line. DELTA in $ delta, GAMMA in $ per 1% move, VEGA in $ per vol point. Customers buying gamma or vega leaves dealers short it.
  • US options. The measured model, with a faint open interest net delta line for reference. VEGA is per session: one bar per session with the running total.
  • Crypto. BTC and ETH aggregate the Deribit, Bybit and OKX tape. STRIKE shows where the delta landed by strike.

What to look for

  • Direction and slope, not the absolute level.
  • A flat line through a big price move is a divergence.

Questions

Why does SOL show a note?

FLOWLINE needs a measured flow source. Among crypto coins that is BTC and ETH.
