Updated Valutakrambod, now also with information from NBX
27th February 2021

I have neglected the Valutakrambod library for a while, but decided this weekend to give it a face lift. I fixed a few minor glitches in several of the service drivers, where the API had changed since I last looked at the code. I also added support for fetching the order book from the newcomer Norwegian Bitcoin Exchange.

I alsod decided to migrate the project from github to gitlab in the process. If you want a python library for talking to various currency exchanges, check out code for valutakrambod.

This is what the output from 'bin/btc-rates-curses -c' looked like a few minutes ago:

Yes, I notice the negative spread on Hitbtc. Either I fail to understand their Websocket API or they are sending bogus data. I've seen the same with Kraken, and suspect there is something wrong with the data they send.

As usual, if you use Bitcoin and want to show your support of my activities, please send Bitcoin donations to my address 15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.
