Trade8:Feed - market data

The market-data tier: it ingests vendor quotes through pluggable adapters (ITCH, IDC, crypto websocket, FIX-MD, simulation), normalizes them into one internal event shape (L1 BBO, trades, depth), and publishes to every consumer.

Use cases​

  • Vendor adapters - each vendor plugs as an adapter; adding a data source is a new adapter, not a core change.
  • One event shape - L1 BBO, trade prints, and depth normalize regardless of the source; Bars, the app, and analytics consume one shape.
  • Simulation - the simulation adapter feeds deterministic test scenarios for strategy and P&L verification.
