B3.MarketData.WebSocketClient

Typed C# subscriber SDK for the B3MarketDataPlatform WebSocket distribution layer.

This v1 release covers the reference-price use case (trade prints, info snapshots, server status) — the same surface documented in docs/WEBSOCKET_API.md, exposed as typed events with the SBE 4-decimal price exponent already applied so consumers never see the raw i64 mantissa.

using B3.MarketData.WebSocketClient;

await using var client = new MarketDataClient(new MarketDataClientOptions
{
    Endpoint = new Uri("ws://localhost:8080/ws"),
});

client.Trade += t => Console.WriteLine($"{t.Symbol}  {t.Price:F4} x {t.Qty}");

await client.ConnectAsync();
await client.SubscribeAsync("PETR4");

Includes:

  • Transparent reconnect with exponential back-off + automatic re-subscribe of every active subscription.
  • Bounded back-pressure (Channel<T> with a configurable policy: DropOldest / Block / Throw).
  • DI extension: services.AddMarketDataClient(...).

Out of scope for v1: full L2/MBO subscription, recovery REST endpoints.

See docs/CLIENT-SDK.md for the full guide.
