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
