FAQ

Frequently asked questions

What is the TickerLayer CFD Data Feed?

The CFD Data Feed gives you index-style and ETF-style market coverage through the same clean TickerLayer integration model. Use the dedicated Indices and ETFs APIs to request symbols, quotes, and historical data, all with consistent response formats, so adding broad market exposure does not mean learning a new API.

Which CFD-style instruments are available?

Coverage focuses on selected global index-style and ETF-style instruments. Use the Indices and ETFs symbol endpoints to see the currently supported, integration-ready symbols (for example broad market index codes and ETF-style basket symbols) rather than guessing what is available.

Why use CFD-style market data?

It is a clean way to add broad market context without wiring up a separate workflow for every reference instrument. With one consistent API, you can build dashboards, watchlists, analytics tools, market overview pages, and internal monitoring screens that reflect the wider market at a glance.

Can I access CFD data through REST and WebSocket?

Yes. Use the Indices and ETFs REST APIs for request-based work like quotes, symbol discovery, and historical bars. For live experiences, use the supported Indices and ETFs WebSocket channels once they are enabled for your account.

What can developers build with the CFD Data Feed?

Think index dashboards, ETF basket views, watchlists, portfolio analytics, macro market screens, research tools, and customer-facing finance interfaces. The feed earns its keep whenever you need broad market coverage with simple integration and predictable data shapes.

What should I know before using CFD data?

This data is intended for informational, analytical, display, and integration use. Before relying on it in production, review symbol coverage, response timestamps and fields, and your plan access against your specific product requirements so there are no surprises once it is live.
