Aggregate Trade Streams

The Aggregate Trade Streams push market trade information that is aggregated for fills with same price and taking side every 100 milliseconds. Only market trades will be aggregated, which means the insurance fund trades and ADL trades won't be aggregated.

After CM migration, the payload is appended with a new st field (1 = UM, 2 = CM).

All Market Liquidation Order Streams

The All Liquidation Order Snapshot Streams push force liquidation order information for all symbols in the market. For each symbol，only the latest one liquidation order within 1000ms will be pushed as the snapshot. If no liquidation happens in the interval of 1000ms, no stream will be pushed.

After CM migration, this stream pushes the merged UM + CM universe (subscribable on both fstream and dstream); each payload is appended with a new st field (1 = UM, 2 = CM) and a new ps field (pair symbol).

Multi-Assets Mode Asset Index

Asset index price. Subscribe with !assetIndex@arr for all assets, or <assetSymbol>@assetIndex for a specific asset.

CM-UM Integration (Effective 2026-06-30): Renamed from Multi-Assets Mode Asset Index. The stream !assetIndex@arr now additionally pushes COIN-M settlement-asset price index entries (e.g., BTCUSD, ETHUSD, BNBUSD). The on-the-wire stream key is unchanged; existing subscriptions continue to work.
