Websocket Streams

Our platform provides two methods for obtaining price feeds.

  1. General - the best pricing feeds for token pairs in general.

  2. Specific for a maker - the best token pairs pricing feeds for a specific maker.

General Pricing Data

General pricing data allow us to connect to two different streams.

  1. General stream

  2. Request stream

General stream

The best price stream contains two sides of a token pair.
