+Title: Updated Valutakrambod, now also with information from NBX
+Tags: english, bitcoin
+Date: 2021-02-27 13:30
+
+<p>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.</p>
+
+<p>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
+<a href="https://gitlab.com/petterreinholdtsen/valutakrambod">code for
+valutakrambod</a>.</p>
+
+<p>This is what the output from '<tt>bin/btc-rates-curses -c</tt>'
+looked like a few minutes ago:</p>

+<p>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.</p>
