Frequently Asked Questions
Everything you need to know before using the API.
Q
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.
Q
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.
Q
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.
Q
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.
Growth
billed annually ($2,868/yr)
Built for the same-day clock: live pin risk, the flow-adjusted magnet, intraday gamma regime and the scored 0DTE strategy signal, refreshed every 15 seconds.
- Live pin risk + flow-adjusted magnet - refreshed every 15s against the decay clock
- Intraday gamma regime and flip - know when moves extend vs fade
- 0DTE strategy signal - a scored same-day range-compression read
- 2,500 requests/day - polling every 30s through the whole session
When Alpha instead: the raw print tape and OI simulator underneath the pin score, ~1s snapshots for scalp timing, and minute replay of past 0DTE sessions to study how pins resolved.
