SBE Market Data Streams

General Information​

• The base endpoint is stream-sbe.binance.com or stream-sbe.binance.com:9443.
• To retrieve market data in JSON format, please refer to this page.
• SBE schema used for decoding the streams can be found here.
• All symbols in stream names are lowercase.
• You can subscribe to a single stream at /ws/.
• You can subscribe to multiple streams at /stream?streams=//.
• A single connection to stream-sbe.binance.com is only valid for 24 hours; expect to be disconnected at the 24 hour mark.
• All time and timestamp fields are in microseconds.
• An API Key is necessary for access.
  • Only Ed25519 keys are allowed.
  • Please put your API Key in the X-MBX-APIKEY header when opening the connection. Timestamp and signature are not necessary.
  • No extra API key permissions are necessary to access public market data. Symbol whitelist also does not affect access to SBE Market Data Streams.
  • However, if you use an IP whitelist for the API key, only specified IP addresses are allowed to use the API key.
• The server sends a ping frame every 20 seconds.
  • If the server does not receive a pong frame back from you within a minute, the connection will be closed.
  • When you receive a ping, you must send a pong with a copy of ping's payload as soon as possible.
  • Unsolicited pong frames are allowed, but will not prevent disconnection. It is recommended that the payload for these pong frames are empty.
• Live Subscribing and Unsubscribing is also supported.
  • You must send the subscription requests in JSON, and will receive the subscription response also in JSON.
  • You can differentiate subscription responses from market data events by looking at the WebSocket frame type: subscription responses are always sent in text frames (containing JSON), and events are always sent in binary frames (containing SBE).
• If your request contains a symbol name containing non-ASCII characters, then the stream events may contain non-ASCII characters encoded in UTF-8.

WebSocket Limits​

• WebSocket connections have a rate limit of 5 requests per second.
  • Only messages from your client are considered:
    • PING frame
    • PONG frame
    • Text frame with JSON control request
  • Events pushed by the server are not rate-limited.
  • Connections that go beyond the limit will be closed. Repeatedly disconnected IP addresses may be banned.
• A single connection can listen to a maximum of 1024 streams.
• There is a limit of 300 connection attempts every 5 minutes per IP address.

Available Streams​

Trades Streams​

Raw trade information, pushed in real-time.

SBE Message Name: TradesStreamEvent

Stream Name: @trade

Update Speed: Real time

Best Bid/Ask Streams​

The best bid and ask price and quantity, pushed in real-time when the order book changes.

[!NOTE] Best bid/ask streams in SBE are the equivalent of bookTicker streams in JSON, except they support auto-culling, and also include the eventTime field.

SBE Message Name: BestBidAskStreamEvent

Stream Name: @bestBidAsk

Update Speed: Real time

SBE best bid/ask streams use auto-culling: when the system is under high load, it may drop outdated events instead of queuing all events and delivering them with a delay.

For example, if a best bid/ask event is generated at time T2 when there is still an undelivered event queued at time T1 (where T1 < T2), the event for T1 is dropped, and the system will deliver only the event for T2. This is done on a per-symbol basis.

Diff. Depth Streams​

Incremental updates to the order book, pushed at regular intervals. Use this stream to maintain a local order book.
