Account & History Streams

Order, balance, activity, and trade WebSocket endpoints

Use these streams for private account events and public history broadcasts.

Endpoint pages

• Order Updates — order execution and TP/SL status events

• Balance Updates — initial balance snapshot and live balance deltas

• Order Feed — live order status events from the history service

• Activity Feed — live event activity with subscribe and unsubscribe

• Last Trades Feed — public stream of the latest platform trades

Shared authentication

Only private streams need auth:

• Order Updates

• Balance Updates

• Order Feed

Send this message after connect.

{
  "t": "AUTH",
  "d": {
    "apiKey": "<API_KEY>",
    "signature": "<SIGNATURE>",
    "timestamp": "<UNIX_EPOCH_SECONDS>"
  }
}

Build signature from timestamp + "GET" + path.

After reconnect, authenticate again and restore every subscription.

Public streams

• Activity Feed is public. Use subscribe and unsubscribe messages.

• Last Trades Feed is public. Connect and read messages.

When to use which stream

• Use Order Updates right after placing or changing orders.

• Use Balance Updates for wallet and position balance changes.

• Use Order Feed for history-service order events.

• Use Activity Feed for per-event live activity.

• Use Last Trades Feed for public trade tape style updates.
