  description: 'Lukka''s WebSocket streaming surface for institutional digital-asset market data: executed trades, Level-1
    order-book quotes, Lukka Prime pricing, Lukka Index valuations, Standard and Median Reference Rates, real-time MVWAP,
    derivative Greeks, and prediction-market trades and quotes.


    Every stream is authenticated with a Lukka-issued JWT bearer token supplied as the `access_token` query parameter on the
    connection URL. Tokens expire; the server emits a token-expiry notice and the client reauthorizes in-band with an `authenticate`
    action message. Subscriptions are managed in-band with `subscribe` / `unsubscribe` action messages carrying pair codes,
    source ids and asset codes. Several streams support a ping/pong heartbeat.'

  x-documentation-issues:
  - channel: Lukka Index Websocket
    issue: 'The published documentation gives two different hosts for the same stream: the prose says wss://market-data-trades-ws.lukka.tech/v3/index
      while the URL block says wss://market-data-ws.lukka.tech/v3/index. This document uses the URL block, which matches the
      other v3 streams.'
  - channel: Lukka Index Websocket
    issue: The published Subscribe (Client) example is not valid JSON (unbalanced braces and a trailing comma), so no subscribe
      message example is carried for this channel. It is not reconstructed here.
