User fills

Endpoint: wss://api.testnet.arcus.xyz/v1/ws — one socket multiplexes every channel and RPC request. Click Connect, then send the example subscribe message below to start receiving data.

Per-user fill stream. Snapshot on subscribe contains recent fills; streaming updates deliver each new fill as orders are matched. Snapshot is sent once on connect only.

LIQUIDATION and ADL fills also appear here (taker-side), so subscribers tracking realized closures can observe forced fills on either account or userFills.
