Flags¶

Only notable flags are mentioned here. Please refer to roq-kraken --help for all flags.

--book_depth: Maximum order book depth. The exchange will limit order book updates to this depth. Please refer to Kraken Websockets API for further details.

Ansible ¶

Add your host to the roq_kraken group

[roq_kraken]
MY_SERVER

Docker ¶

docker pull roqtrading/roq-kraken

Implementation¶

Restrictions¶

Order book ends up in bad state: Downtime (scheduled or not) appears to not shutdown existing connections nor are established subscriptions unsubscribed. Worse, during downtime, what appears to be uninitialized order book data can be disseminated. (This was confirmed with Kraken support early May 2020).

Warning

We currently have no means to detect bad order book updates. At best, a parse exception will terminate your gateway with an unhandled excpetion.
