Looking for trading websocket api documentation


Does anyone have the link to the trading websocket (wss://api.alpaca.markets/stream) documentation?

I believe I saw the doc in the past, but can’t find it anymore.


Hi Nan_Qin, the web socket endpoint is wss://stream.data.alpaca.markets/v2/{source} … Here’s the link to Market Data API documentation page.

Hi @waimun.ng the document I am searching is for order events, not the market data. And the order events come from “wss://api.alpaca.markets/stream”.
