Streams#

Type

Comments

REST

Primary purpose

  • discover the full list of symbols

Type

Comments

WebSocket

Primary purpose

  • live market data

Each connection

  • supports a slice of the symbols

Constraints#

Comments#

  • The rate-limiter is quite strict

    • Currently getting errors when subscribing more channels…!?

    • Maybe need a queue for subscribtions…

    • Also, there’s a warning about not subscribing during the first second

  • Market data

    • Book is full snapshot on each update (must convert to incremental)

    • Need custom parser for book due to nested arrays
