Frequently asked questions

Is the AAOI price on this page real-time?

No. The price, the ranges, and the chart are delayed by at least 15 minutes and refresh periodically. They are here so you can see the instrument the API serves before you integrate. Real-time AAOI data is delivered through the REST snapshot and quote endpoints and the WebSocket channels on an API key.

Where does the AAOI data come from?

TickerLayer builds derived, indicative market data from non-exchange inputs such as CFD-style pricing references, contributor pricing, and over-the-counter activity, normalized into one schema across every asset class. It is not official venue data and should not be presented to your users as such.

How do I get AAOI market data through the API?

Call GET /stocks/snapshot/US:AAOI for the latest price, previous close, and change, GET /stocks/quote/US:AAOI for bid and ask, and GET /stocks/agg/US:AAOI/1/day/{from}/{to} for OHLCV bars. Subscribe to stocks.quotes or stocks.trades on the WebSocket to stream updates as they happen.

Which bar intervals are available for AAOI?

One, five, and fifteen minute bars, one and four hour bars, and daily bars, each with a documented maximum window per request. Daily history reaches back several years for most instruments; intraday history is capped by interval so responses stay fast.

Can I show AAOI data to my own users?

Yes, inside your product or workflow on a commercial plan. Redistributing the raw feed, reselling it, or publicly displaying it as a standalone data product needs a separate agreement. If your use case looks like any of those, talk to us before you launch.

Is AAOI available on the free tier?

Every account starts with 3,000 free REST requests a month, which is enough to integrate and test any stock. Paid plans add volume, WebSocket streaming, and commercial use.

Delayed, derived, indicative data for informational and integration purposes. Not official venue data, not investment advice, and not a system of record. See the market data disclaimer.
