  title: DFlow Trading API WebSocket Streams
  version: 0.1.0
  description: >-
    DERIVED event surface for the DFlow Trading API real-time WebSocket streams.
    Modeled by API Evangelist from the published DFlow docs
    (https://pond.dflow.net/resources/trading-api/websockets/overview and the
    /spot/recipes/stream-* recipes); DFlow does not publish a native AsyncAPI
    document. Channels stream live market data (top-of-book quotes, order-book
    depth, and priority-fee estimates) over WebSocket. Not a webhook/callback
    surface — these are client-subscribed read streams.
