Channels

Complete reference for all WebSocket data channels, subscription parameters, and message formats.

This page documents all available WebSocket channels, their subscription parameters, and the data format for each message type.

For full type definitions, see the Types page.

Message Format

All data messages follow this structure:

{
  "type": "data",
  "channel": "<channel_name>",
  "exchange": "<exchange_id>",
  "symbol": "<symbol>",
  "tf": "<timeframe>",
  "id": "<subject>",
  "data": { ... }
}

Field	Type	Description
`type`	string	Always `"data"` for data messages
`channel`	string	Channel name (e.g., `"candles"`, `"trades"`)
`exchange`	string	Exchange ID (e.g., `"binancef"`). Aggregated streams use colon-separated, unique, alphabetically ordered IDs (e.g., `"binancef:bybitf"`). Invalid aggregate strings return `INVALID_EXCHANGE`.
`symbol`	string	Trading pair (e.g., `"btc/usd"`)
`tf`	string	Timeframe string, included for channels that use timeframes
`id`	string	Subject identifier (e.g., `"candles.binancef.btc/usd.60"`)
`data`	object	Channel-specific data payload

The tf field is included for channels that use timeframes (candles, stats, oi, vd, volumes, heatmap_sd, heatmap_hd, flat_heatmap_sd, flat_heatmap_hd, stop_heatmap, tp_heatmap, liquidation_heatmap). It contains a human-readable timeframe string like "1m", "5m", "1h", "1d".

stop_heatmap, tp_heatmap, and liquidation_heatmap must use a single exchange ID (no aggregated exchanges), and are available only for hyperliquid and hyperliquid-xyz.

The id field contains the subject publish string that uniquely identifies this data stream. For example, "candles.binancef.btc/usd.60" for 1-minute candles on Binance Futures BTC/USD.

Handling Orderbook Updates

Messages contain only the levels that changed since the last update. Maintain local orderbook state and apply updates:

quantity > 0: Set or update the level at that price
quantity = 0: Remove the level at that price

// Local orderbook state
const orderbook = {
  asks: new Map(), // price -> quantity
  bids: new Map(), // price -> quantity
  lastPrice: 0
};

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);

  if (msg.channel === 'depth') {
    // Apply ask updates
    for (const [price, qty] of msg.data.a) {
      if (qty === 0) {
        orderbook.asks.delete(price);
      } else {
        orderbook.asks.set(price, qty);
      }
    }

    // Apply bid updates
    for (const [price, qty] of msg.data.b) {
      if (qty === 0) {
        orderbook.bids.delete(price);
      } else {
        orderbook.bids.set(price, qty);
      }
    }

    orderbook.lastPrice = msg.data.lp;
  }
};

Snapshots

Full orderbook snapshots are sent every ~60 seconds as a consistency checkpoint. Snapshots contain all levels currently in the book. You can identify a snapshot by the larger number of levels compared to regular updates.

After reconnection: Clear your local orderbook state and rebuild from incoming messages. The first message after subscribing will help establish state, and periodic snapshots ensure consistency.

stats

Market statistics including funding rates, liquidations, orderbook depth metrics, and TPS (trades per second).
