What does the ETFs market data API return?

The market prices of exchange-traded funds as JSON: bid and ask, the last trade, snapshots with change metrics, and OHLCV bars. The same data streams over WebSocket on etfs.quotes and etfs.trades, with closed bars on etfs.agg.

How do I find an ETF symbol?

Two naming styles work side by side: generic codes that describe the exposure, such as US500ETF or USGOLD, and the listing ticker of the fund. GET /etfs/symbols returns every code with its name, and the symbol coverage checker resolves a whole watchlist.

Does the feed include NAV or holdings?

No. This is market data for the fund as a traded security. NAV, the intraday indicative value and holdings files are fund data, and they come from each fund.

What happens to ETF quotes outside US regular hours?

Outside 09:30 to 16:00 ET a US ETF quote is published while its spread stays within 0.5% of the mid. Send "spread": "full" on etfs.quotes, or ?spread=full on /etfs/quote, and the wider books arrive too.

Are these official exchange prices?

ETF prices on TickerLayer are indicative, derived market data, not official exchange data, and they may differ from official prices. Observed behaviour is published on the ETF data quality page.

Are ETFs and indices the same feed?

No. They are two feeds with their own prices and plans, on the same API key. An ETF is a traded fund with quotes and trades of its own; an index is a calculated level. See the indices market data page for the other feed.
