Yesterday, the Kraken virtual currency exchange announced
-their
-Websocket service, providing a stream of exchange updates to its
-clients. Getting updated rates quickly is a good idea, so I used
-their API
-documentation and added Websocket support to the Kraken service in
-Valutakrambod today. The python library can now get updates
-from Kraken several times per second, instead of every time the
-information is polled from the REST API.
-
-
If this sound interesting to you, the code for valutakrambod is
-available from
-github.
-Here is example output from the example client displaying rates in a
-curses view:

Yes, I notice the strange negative spread on Hitbtc. I've seen the
-same on Kraken. Another strange observation is that Kraken some times
-announce trade orders a fraction of a second in the future. I really
-wonder what is going on there.
