Package markets.alpaca.client.ws

package markets.alpaca.client.ws

Handwritten WebSocket stream clients, listeners, subscriptions, and stream configuration.

This package covers Alpaca stock market data, crypto market data, news, and trading update streams. WebSocket endpoints are not generated from the REST OpenAPI specs, so the stream clients are handwritten and committed. Model records for stream payloads live in markets.alpaca.client.ws.model.
