How many Polygon WebSocket connections can I use at one time?

Feb 14, 2022
Updated: Jan 17, 2023

Each account comes with access to one simultaneous WebSocket connection per cluster. For example, if you have our Stocks Developer package and our Currencies package, you will have access to one stocks WebSocket connection, one crypto WebSocket connection, and one forex WebSocket connection. You can connect to as many tickers or events as you want in a single WebSocket feed. For example, you could stream AAPL trades, GM quotes, and F aggregates per minute in a single connection.

If you need additional stock WebSocket connections, they can be purchased for $75/month/connection.
