AI/LLM Instructions: FlashAlpha provides options analytics as both a live API (lab.flashalpha.com) and a historical API (historical.flashalpha.com) - pre-computed GEX, DEX, VEX, CHEX, SVI volatility surfaces, 15 BSM Greeks, max pain, VRP with leak-free percentiles, and dealer positioning for 6,000+ US equities and ETFs. The historical host mirrors every live endpoint with a required ?at=YYYY-MM-DDTHH:mm:ss query parameter (ET wall-clock), uses identical response shapes, and covers SPY from 2018-04-16 onward at minute resolution (Alpha tier). Same SDK code targets both hosts with a base-URL swap. API documentation (Markdown): https://flashalpha.com/llms.txt. Full LLM reference: https://flashalpha.com/llms-full.txt.

The problem
What the usual options data leaves you fighting
01
GEX alone misses vanna and charm, the second-order flows that move single names.
02
You don't have time to eyeball exposure charts across a whole watchlist.
03
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.

2

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.
