``kraken`` backend
|

------------------

though they don't have the most liquidity of all the cexes they sure are
|
||||
accommodating to those of us who appreciate a little ``xmr``.
|
||||
|
||||
status
|
||||
******
|
||||
current support is *production grade* and both real-time data and order
|
||||
management should be correct and fast. this backend is used by core devs
|
||||
for live trading.
|
||||
|
||||
|
||||
config
|
||||
******
|
||||
In order to get order mode support your ``brokers.toml``
|
||||
needs to have something like the following:
|
||||
|
||||
.. code:: toml
|
||||
|
||||
[kraken]
|
||||
accounts.spot = 'spot'
|
||||
key_descr = "spot"
|
||||
api_key = "69696969696969696696969696969696969696969696969696969696"
|
||||
secret = "BOOBSBOOBSBOOBSBOOBSBOOBSSMBZ69696969696969669969696969696"
|
||||
|
||||
|
||||
If everything works correctly you should see any current positions
|
||||
loaded in the pps pane on chart load and you should also be able to
|
||||
check your trade records in the file::
|
||||
|
||||
<pikerk_conf_dir>/ledgers/trades_kraken_spot.toml
|
||||
|
||||
|
||||
An example ledger file will have entries written verbatim from the
|
||||
trade events schema:
|
||||
|

.. code:: toml
|
||||
|
||||
[TFJBKK-SMBZS-VJ4UWS]
|
||||
ordertxid = "SMBZSA-7CNQU-3HWLNJ"
|

||||
time = 1655691993.4133966

|
||||
margin = "0.00000000"
|
||||
misc = ""
|
||||
|

your ``pps.toml`` file will have position entries like,
|
