The problem

What the usual options data leaves you fighting

GEX alone misses vanna and charm, the second-order flows that move single names.

You don't have time to eyeball exposure charts across a whole watchlist.

Levels shift intraday, so you end up trading yesterday's walls.

What FlashAlpha gives you

Get the full exposure picture and a narrative on top: where the gamma flip and walls are, how vanna and charm tilt the hedging, and what it means in plain English per name.

Questions, answered

What does the AI narrative include?

A plain-English read of the gamma regime, day-over-day GEX change, key levels in context, notable OI flow, vanna/charm interpretation and an outlook, with the structured numbers backing each line.

What's the difference between GEX, DEX and VEX?

GEX is gamma exposure (how hedging dampens or amplifies moves), DEX is delta exposure, VEX is vanna exposure (delta's sensitivity to vol). Together they explain dealer hedging more completely than GEX alone.

Which plan do I need for the narrative?

GEX (single expiry) and key levels are Free; the AI narrative, exposure summary and full-chain GEX are Growth.

Which names are supported?

Any US equity or ETF with listed options; index symbols require Basic or higher.

Recommended plan

Growth $239/mo

billed annually ($2,868/yr)

Growth unlocks full-chain GEX, the exposure summary and the AI narrative, dealer positioning as a read, not a chart.
