The problem

What the usual options data leaves you fighting

Pin risk and the gamma flip move every minute, end-of-day data is useless intraday.

You can't see the magnet strike or how today's flow is adjusting it in real time.

Positive versus negative gamma flips your playbook, and you find out too late.

What FlashAlpha gives you

A purpose-built 0DTE view: pin-risk magnet with a four-part score, expected move that shrinks toward the close, dealer hedging at ±0.1/0.25/0.5/1%, and the live flow tape behind it.

Questions, answered

What is the pin-risk score?

A 0–100 composite of OI concentration (30%), magnet proximity to spot (25%), time remaining (25%) and gamma magnitude (20%), with each sub-score exposed so you can see why it's high or low.

Which indexes have daily 0DTE?

SPY has 0DTE every trading day. FlashAlpha's SPX 0DTE coverage is limited, so the endpoint returns no_zero_dte on days SPX has no same-day expiry and gives you the next one. Always check the flag.

Do I need Growth or Alpha for 0DTE?

0DTE analytics and live pin risk are Growth. The live flow bundle and raw OI simulator state are Alpha.

How fresh is the data?

Computed on demand against the latest snapshot, with a snapshot-age field so you can gate on staleness near the close.

Recommended plan

Growth $239/mo

billed annually ($2,868/yr)

Growth covers 0DTE analytics and live pin risk; Alpha adds the live flow tape and raw OI simulator for print-by-print reads.
