tastytrade DXLink Market Data Streaming API

Real-time market data streaming via DXLink, a WebSocket-based protocol backed by dxFeed.

Supports subscriptions to quotes, greeks (implied volatility, delta, gamma, theta, vega), candles, and other market events for equities, options, futures, and crypto instruments. Sandbox quotes are 15-minute delayed.
