Stream Account Events

  • Available in Paper Trading
  • Available in Production
  • Available to Advisors
  • Supported

Note: This API is presently in Beta. It is only available to Tradier Brokerage account holders and should only be used in production applications with caution.

Stream account updates using WebSocket streaming. You will receive a different payload depending on the account event that occurred. Details about each event can be found in the response definition. You can continually update the data in your stream by resending this request with different parameters.

Note: In order to stream data, you must first create a streaming session. Upon receiving a sessionid, you will have up to 5 minutes to connect to a streaming endpoint before the session expires.

Once connected and streaming data, to make modifications to your current streaming connection, simply resend your request payload using the existing sessionid. Note: if your sessionid has expired, you will need to get a new one and send it with your adjusted payload.

Note that WebSocket streaming uses a different endpoint: wss://ws.tradier.com
While we do not publish the symbol limits for these APIs, we do monitor for abuse to make sure people aren’t doing anything egregious (like asking for an entire exchange worth of symbols). Essentially, ask for what you need. Don’t abuse the APIs and you should be fine. It is not permitted to open more than one session at a time.
