Kraken Plugin (crypto trading) - 09/09/17 07:58

Hi,
I just shared the code for a Kraken plugin.

https://github.com/vinsom68/Zorro-Kraken-Plugin

There is also a compiled dll and instructions.
There are a few issues, expecially for pairs who have many decimals described in the readme.
This is the first plugin of this kind for Zorro, and it might need some updates to be fully compatible with crypto.

Use at your own risk.
This is the first version, and there might be bugs.
Mostly tested with Bitcoin as base currency, but other currencies might be experimented.

I will work next on a plugin for Bittrex, as I'm mostly trading on this exchange now.

Enjoy
Vincenzo

Hi Jcl,
To work properly with crypto, Zorro would need to display more than 5 decimals, up to 10.

- The Account balance doesn't display any decimals, so if you have your account in bitcoin, and a balance of less than 1 bitcoin you will see only 0.
- for some pairs that have many decimals , like DOGE/BTC, trading small amounts you will see only 0s in the Zorro log and Report.

Would be nice to have a configurable number of displayed decimals.

Thanks
Vincenzo

Thanks for the plugin! And yes, we'll have to make decimals configurable for cryptos.

Bittrex plugin should be finished in a couple of weeks.
This one much easier to do than the kraken one.

Hey Vincenzo and thank you for the plugins!

I managed to run the Bittrex one successfully but with Kraken the authenticated part doesn't work for me. I get this every time:

Any idea what could be the cause? I'm using Zorro S 1.66 and I followed the instructions from README on Github, DemoTrading is set to "0".

Re: Kraken Plugin (crypto trading) - 10/19/17 09:04

Hi pcz, are you using the Assetlist.csv specific for Kraken that I posted with the code readme ?
Also can you post the Kraken zorro.ini keys below that you set ?

DisplayCurrency="USD"
BaseTradeCurrency="XBT"

Cheers

Re: Kraken Plugin (crypto trading) - 10/19/17 09:07

Also if you enable the log with EnableLog="1" you should be able to find the json response from Kraken in the KrakenPluginLog file inthe log folder.

Yes, I had it in AssetsFix.csv file together with Bittrex symbols but now I tried moving it to a separate file (and loading using assetList function) with no difference.

I have enabled logging, what I posted above are the only lines that appear in the log. The currencies are fine too - I just copy/pasted everything from the Github page.

Do I need a funded account in order to be able to use the API or is zero balance OK? If you want I can PM you the keys and you can try / debug.

Re: Kraken Plugin (crypto trading) - 10/19/17 10:21

Yes you are right, the Kraken account must be funded. I had the same issue the first time calling the API.
Here there is the response from Kraken Support when I had the issue:

Andy (Kraken Support)
Jul 28, 04:51 PDT

Hi Vincenzo,

I'm Andy from Kraken Client Engagement team. Sorry for the late response, our support team has been under heavy load lately.

Balance is not returned for the assets that were never used. Please deposit or buy a small amount of each asset that you want to get via API

Please, let us know if there's anything else we can assist you with. And have a good day!

Regards,

Andy

@vinsom, thanks for sharing this plugin. Now, trading in cryptos would be much more fun

I'm having a few issues trying to connect to Kraken. My first attempt was to download the BCH/EUR historic data, but got this error:

Quote:
Login Kraken..
!syntax error at line 1 near: <!DOCTYPE html>
!/0/private/TradeBalance - Error Parsing JSon
!Error calling API BrokerAccount
!Can't Login - Retry
Can't connect!


As an initial test, I created the Kraken API allowing export data only. Plugged "API Key" as PublicKey and "Private Key" as it is on the Zorro.ini file. Additionally, these are my other setups:

Quote:
DisplayCurrency="EUR"
BaseTradeCurrency="BCH"
EnableLog="1";
UseCryptoCompareHistory="1"


On the Zorro 1.66 UI, filled the parameters as:
User: nothing
Account: Real / Kraken
Script: Download BCH/EUR

Placed Kraken.dll within /Plugins folder and remaining files inside a subfolder named /Plugins/kraken.

Your comments are much appreciated.

UPDATE: it's worth to mention I tried including assets in AssetsFix.csv and in a separate file as well, in which case I modify Account.csv file accordingly. Additionally, besides public and private API credentials, I plugged my user/password I use to log into Kraken's site in the Zorro's UI user parameter. None worked as expected

Re: Kraken Plugin (crypto trading) - 01/20/18 14:50

I bought and sold BCH, ETH and ETC via Kraken, so these currencies are 'used' already in my account. But I succeed only in trading BCH/EUR via Zorro, trying ETH/EUR or ETC/EUR results in:

Quote:
Login 0 Kraken.. at UTC 01-20 14:03
!Error MinOrderSize missing. "type mismatch! call is<type>() before get<type>()" && is<double>()
Error 055: No ETH/EUR prices
Logout.. ok

Login 0 Kraken.. at UTC 01-20 14:03
!Error MinOrderSize missing. "type mismatch! call is<type>() before get<type>()" && is<double>()
Error 055: No ETC/EUR prices
Logout.. ok

These pairs are identically set in my Assets.csv

Quote:
BCH/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,BCH/EUR
ETC/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,ETC/EUR
ETH/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,ETH/EUR

Any ideas?

Another question: is it sure to do currency trading via API although no leverage is set? From their docs setting a leverage distinguishes between buying a currency and currency pair trading.

Re: Kraken Plugin (crypto trading) - 01/20/18 21:09

Hi Sphin,
Sorry I made this plugin and tested it only for trading between Crypto.
Never tried with fiat currency.
So as usual do it at your own risk.

For the error you mention you can play with the MinOrderSize in the Zorro ini (see readme on github).
Not sure can fix this issue.


Leverage is always set to 1 (hardcoded) with this plugin.
Posted By: Sphin

Re: Kraken Plugin (crypto trading) - 01/21/18 19:46

Setting leverage to none should be okay first of all but access to other currency pairs would be helpful.
I only can take the minimum sizes Kraken has set but these are original your settings in the Zorro.ini section, I can't see any error there.
Do you think there is a difference if a fiat currency is used? I guess they are treated the same way as cryptos.
Maybe any other user has an idea, I fear my possibilities to debug are very limited at this point.

Re: Kraken Plugin (crypto trading) - 01/31/18 20:01

Hi Sphin,
Give me a bit of time.
Will try to debug it as soon as I have a couple of hours.

Cheers

Re: Kraken Plugin (crypto trading) - 01/31/18 20:21

No problem at all! Glad that someone does this great work anyway, take you time!
Posted By: vinsom

Re: Kraken Plugin (crypto trading) - 01/31/18 22:52

Hi Sphin,
Try this, add as I did below in the zorro ini at the end "EUR":10 and let me know if it works.
In this care I set 10 Euro as minimum order size.
Cheers

MinOrderSize={"error":[],"result":{"REP":0.3,"XBT":0.002,"DASH":0.03,"XDG":3000,"EOS":3,"ETH":0.02,"ETC":0.3,"GNO":0.03,"ICN":2,"LTC":0.1,"MLN":0.1,"XMR":0.1,"XRP":30,"XLM":300,"ZEC":0.03,"BCH":0.002,"EUR":10}}
Posted By: Sphin

Re: Kraken Plugin (crypto trading) - 02/01/18 16:58

It didn't change anything but I don't know if the problem is really related to EUR because as I stated already above: BCH/EUR works!
I get the type mismatch error only choosing any other pair like ETH/EUR or ETC/EUR.
Posted By: vinsom

Re: Kraken Plugin (crypto trading) - 02/03/18 20:37

Hi Sphin,
So finally found some time to do some debugging.
Issues are due do the Kraken naming conventions for pairs.
So to let it work with fiat please do:

in Zorro.ini (note the ZEUR and XETH changes):
DisplayCurrency="ZEUR"
BaseTradeCurrency="ZEUR"
IntervalSec = "30"
DemoTrading="1"
EnableLog="1"
UseCryptoCompareHistory="1"
MinOrderSize={"error":[],"result":{"REP":0.3,"XBT":0.002,"DASH":0.03,"XDG":3000,"EOS":3,"ETH":0.02,"ETC":0.3,"GNO":0.03,"ICN":2,"LTC":0.1,"MLN":0.1,"XMR":0.1,"XRP":30,"XLM":300,"ZEC":0.03,"BCH":0.002,"XETH":0.02}}

and in your asset list(notice the last column):
BCH/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,BCH/ZEUR
ETC/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,XETC/ZEUR
ETH/EUR,50,0,0,0,0.00000001,0.01,0,1,1,0,XETH/ZEUR

Not sure how your BCHEUR has been working with your current setting as is't not working for me with my settings.

To know the naming conventions for their pairs please cann this API from the browser:
https://api.kraken.com/0/public/AssetPairs

Cheers

Re: Kraken Plugin (crypto trading) - 02/03/18 23:31

This is much better but I had to change in the last line of Zorro.ini:
XBT -> XXBT
ETC -> XETC
LTC -> XLTC

BCH is now the only asset I can't get but this doesn't matter anyway. Thanks for your help!

You wrote @GitHub:
Quote:
Zorro works with market orders that have a higher fee 0.26% than limit orders 0.16%

Does this mean an entry limit is useless or controled by Zorro only and OrderLimit is not possible with the Kraken API?
Posted By: vinsom

Re: Kraken Plugin (crypto trading) - 02/20/18 00:27

hi Sphin,
When I developed the plugin Zorro was only able to do market orders.
So the plugin now only support market orders.

I think this changed with recent Zorro version.

Kraken API yes support Limit orders.

Cheers

Re: Kraken Plugin (crypto trading) - 02/21/18 19:54

That's really fine! But as far as I understood Kraken's trading fees are hardly to calculate because one can't know in advance if his order matches an order already in their order book though the chances to be a maker are surely higher with a limit order. Together with the discount concerning to ones cummulative turnover I guess it's more useful to take any averaged value. laugh

Re: Kraken Plugin (crypto trading) - 07/03/18 12:06

Hi vinsom. Maybe you you could look at this post? I'm having trouble understanding how to use your CryptoCompareAPI.
I'm having an error. ( I attached it in the post) I think it's simply I don't understand what is the process flow or step by step actions I need to take to make it work.
Thanks.
