Hey,

I'm new to the krakenex API, i'm trying to do the following

import krakenex
import time

class krakencom():
    def __init__(self):
        self.k = krakenex.API(key='abc',secret="def")

    def getEthEur(self):
        self.etheur = self.k.query_public('Ticker', {'pair': 'ETHEUR'})["result"]['XETHZEUR']
        return self.etheur

    def lowestPrice(self, cur):
        lowestPrice = cur['l']
        return lowestPrice

    def highestPrice(self, cur):
        highestPrice = cur['h']
        return highestPrice

    def volume24h(self, cur):
        volume24h = cur['v'][1]
        return volume24h

    def lastTrade(self, cur):
        lastTrade = cur['c']
        return lastTrade


krak = krakencom()
while True:
    eth = krak.getEthEur()
    print(krak.lastTrade(eth))
    time.sleep(0.5)

the out put is

[‘RESULT', 'RESULT]

and after a while ERROR !!!?!
The error happens randomly from the second query

What are you trying to achieve?

Call the function to make an order, using a variable.

# code sample
value = .02

def single_quote(word):
    single_quote = "'" # single quote
    return single_quote + str(word) + single_quote

print (mykraken.query_private('AddOrder', {'pair': 'XETHZUSD', 'type': 'sell', 'ordertype': 'market', 'price': '20', 'volume': single_quote(value)}))

What do you expect to happen?

A market order to get placed, with parameters of a price of 20 and a volume of .02.

What happens instead?

I get an error message about the volume being an invalid argument.

# error message
{'error': ['EGeneral:Invalid arguments:volume']}

Could you print a list of available commands like below:

balance = k.query_private('Balance')
orders = k.query_private('OpenOrders')

Hi all,
I'm not able to get my balance on Kraken. Here's how I do it.

    self.api_key = 'XXXX'
    self.api_secret = 'XXXXXX'
    conn = krakenex.Connection()
    self.api = krakenex.API(API_KEY, API_SECRET)
    orders = self.api.query_private('Balance')

I get the following: 'EGeneral:Permission denied'.

Any help would be greatly appreciated.

Hello Everyone,

Sorry to ask that, but i have a major Noob question : from a python script, using krakenex, How could you connect to your personal account?

OK there is k.load_key() but nowhere we have to input username, password etc etc.

I think this is a very dumb question but sorry, I've been searching for 1 hour and nothing...

Thanks a lot

The API docs have been updated in the last X years, now more verbosely specifying the allowed call rate.

This could be handled by krakenex, instead of off-loading to client implementations.

Not certain on exact interface to end-user yet.

Current issues are now documented.

To "solve" them, can probably "just give up and use requests", and offload any network issues as "Not My Department".

Need answers:

• Is having a dependency acceptable? (Yes. Otherwise, endless loop of NIH.)
  • So far, krakenex has had no dependencies other than the "standard library". requests is ubiquitous, though, and many distributions provide it as a system-level package, which handles dependencies of requests (urllib3 and chardet on my Arch system, with optional pysocks).
  • Building documentation requires sphinx, which has requests as a dependency.
• Should a "unified" query() be introduced? (No. That can be done independently.)
  • How should it know if an API method is public or private? (See issue #40.)
    • May maintain a list for one of the two, and default to the other one if not in list; or maintain two lists, and refuse to query if in neither list.
    • Currently, the difference is that private methods need to set API-{Key,Sign} headers, and include a nonce in request data.
    • It seems that having a nonce is not enforced by Kraken for public queries.
  • What should its return format be? (JSON, as now.)
    • Whatever requests returns?
    • JSON, as currently output by query_{private,public}()?
• Should the return format of query_{private,public}() remain the same? (Yes - for now, to remain backwards-compatible. Trivial - return request's .json() where appropriate.)
  • Maybe yes, if query() is not introduced, or to remain backwards-compatible.
  • Maybe no, if to be obsoleted or made private; then query() returns JSON, and these two a requests object, verbatim.
• Should manual connection handling remain possible, or become hidden? (Yes. That's the whole point - give users a non-NIH way of customising the connection.)
  • requests handles Keep-Alive.
  • Allowing to set timeout (in Connection.__init__()) may become unnecessary.

Answers may depend on current/planned use cases.

Request should wait till response is returned

See official docs on the topic.

Hi, forgive me if I'm getting this completely wrong, since I'm a novice programmer.

Within the _query function, a check is performed to see if there is a connection object available. If there isn't a new one is created.

if conn is None: if self.conn is None: conn = connection.Connection() else: conn = self.conn

The comments in the code state

If not provided, opens a new connection for this and all
subsequent queries.

However from looking at this code, it seems to me that the connection object would not be re-used for future queries, since it is being assigned to a local reference 'conn' which will be destroyed when the function exits. Therefore each time the function is called a new connection object is created?

Wouldn't the code be something like:
if conn is None: if self.conn is None: self.conn = connection.Connection() else: conn = self.conn

Hi,

I m trying to use the API but I got this issue when I call query public

Can you help me ?

Thanks

I'm starting to use python3-krakenex with a few concurrent scripts, which results in the 'EAPI:Invalid nonce' error fairly frequently, even when I made more API keypairs and implemented a supposed random fetch of one pair per invocation (so making it very unlikely the same one would be picked at the same time, although this clearly doesn't work properly).

The documentation doesn't talk about this, is there any guidance on how to 'scale up' use of python3-krakenex, perhaps somehow share the nonce state? I haven't looked into the implementation yet. Kraken threatens to ban endpoints that create a lot of invalid nonces (which hasn't happened to me yet), so I'm sheepish to fiddle around with settings on Kraken - the settings are locked currently, but I remember something about a nonce window - but I'm betting fiddling with that would not suddenly allow multiple users of a keypair like I want?

hi,
first of all thanks for the great job you did here.

Would there be a way to display the API results messages, more precisely the errors when running a script?
I have used the order-conditional-close.py with success, but some of my calls were wrong at first attempts, and it's pretty hard to debug without knowing what's wrong.

Is there a way to display what Kraken API gives as a feedback?

thanks

Hello,

I wonder why you are not using requests

http://docs.python-requests.org/

It's a great library which could help to have same code for both Python 2 and Python 3.

Expected error to be caught. I believe this is a naive error on my part -- just looking for the proper way to handle.

What happens instead?

I receive the below error message.

# error message

During handling of the above exception, another exception occurred:

Github Pages has an option to read docs from docs dir instead of gh-pages branch.

Keeping doc skeleton in docs-src and building moving built HTML to docs would simplify updating documentation.

Hi,

I'm the developer of clikraken, and I depend on your library to interact with the Kraken API. However you don't provide a package on PyPI, which makes it harder to use it as a dependency in other projects such as mine.

Would you consider packaging it for PyPI? If not, I'm proposing to package it for you and upload it on PyPI myself. Just don't want to step on your toes in case you planned to do it sometime.

Thanks a lot for this library!

This example code you provided. Will occasionally return an object like this

{'error': [], 'result': {'XETHXXBT': {'bids': [], 'asks': [['0.090513', '0.747', 1496336370], ['0.090519', '15.146', 1496336378]]}}}

When asking for a depth of 4. In other words I am 6 orders short. I got no bids... Is there a more consistent order book function I am missing? Why might this be happening?

EDIT: link to commit where Depth.py is still present.

LGPLv3 references GPLv3, but that's not in the repo.

Provide for Mallory.

First mentioned in #10 (comment), with reference to a /r/CryptoCurrency discussion for context.

See PRs #14 and #15 for a (somewhat convoluted) example.

Hi,
I tried out this code as it is until line 45 as a test. Unfortunately my only output is:
{'error': [], 'result': {'trades': {}, 'count': 0}}
Same results when I am going to change the year to 2017 and the change in line 38 to:
end_date = datetime.datetime(2017, i+2, 28)
Does anyone have a solution?
Thank you a lot in advance!
Best regards.

Do you have a list of the asset pair names you could post in the readme?
Is there a link you could give me to find a list that already exists?
If you are wondering what I am looking for the 'pair' parameter is what I am inquiring about. As in this example:

print(k.query_public('Depth',{'pair': 'XXBTZUSD', 'count': '10'}))

I know of the following but it just gives a huge blurb.

print(k.query_public('AssetPairs'))

For instance I want to know what Litecoin to Bitcoin pair name would be.

Close an open connection after timeout

# code sample
def query_order(k, txid):

		options = {'txid':''}
		options['txid'] = txid
		
		try:
			print ("querying open orders")
			values = k.query_private('QueryOrders',options)
			print ("result")
			print (values)
			return values

			print ("query_pair: Unexpected error:", sys.exc_info()[0])
			# probably a timeout, sleep 60 seconds and try again
			k.conn = None
			time.sleep(60)		
		
		return None

What do you expect to happen?

I would like to close/reset the krakenex connection. Since I am running a lot in some sort of endless loop of timeouts, which, miraculously always get resorted after I restart my code.
Now I thought the k.conn = None would sort that issue.
It does, kind of, it creates a new connection and the timeout issue disappears.
However if the bot runs long enough, which now happened after 16h, the shell had so many instances that I was getting socket errors until I closed the entire shell and started in a fresh shell.
My best attempt was k.conn.close() but the below code returns:

# code sample
k.query_public('Ticker',dict([('pair', 'XXBTZEUR')]))
print (k.conn)
k.conn.close()
print (k.conn)
k.query_public('Ticker',dict([('pair', 'XXBTZEUR')]))
print (k.conn)

# message
<krakenex.connection.Connection object at 0x036607B0>
<krakenex.connection.Connection object at 0x036607B0>
<krakenex.connection.Connection object at 0x036607B0>

I don't know, is it really creating a new connection at the next query? if I use my shitty k.conn = None method I get a new memory imprint.

No idea how to handle those infinite timeouts, or well, reset krakenex connection without creating a dead instance.

In CHANGELOG.rst. Possibly in docs if need to be verbose.

Hello,
Actually kraken seems ddos and sometime when i made and order by using AddOrder i have got this:
502 Server Error: Bad Gateway for url: https://api.kraken.com/0/private/AddOrder
The order is set but i don't get the txids :(
Does it's a bug on krakenex or on kraken ?
Don't know but i really need this txids so how can i do ?
Thanks.

Currently krakenex will not work with a proxy/behind a proxy without code change cause it's https requests are based on http.client and urllib.

Best would be to have it based on requests. There the system/OS proxy settings are automatically used.

What I did for krakenex was to change the connection.py. With a proxy at : myserver:1111 it has to be changed from
self.conn = http.client.HTTPSConnection(uri, timeout = timeout)

to

self.conn = http.client.HTTPSConnection("myserver:1111", timeout = timeout)
self.conn.set_tunnel(uri)

Using query_private with leverage result in error, but somehow kraken still accept the order.

using Windows 10, with python 3.6.

The code :

## Test open long posiition
print(k.query_private('AddOrder',
                {'pair': 'USDTUSD',
                 'type': 'buy',
                 'ordertype': 'market',
                 'volume': '5',
                 'leverage': '2'}))

I'm trying to import krakenex and run it with cmd + b in Sublime Text on OSX.

# code sample

What do you expect to happen?

I expect to be able to run the example open-positions.py

What happens instead?

When pressing cmd + b, I get
"import krakenex
ImportError: No module named krakenex"

If I create a new file that just says "print 'hello world'" and then press cmd + b, it does print 'hello world'.

However, krakenex is not imported when I press cmd + b within open-positions.py.

The problem is probably very basic. I learned python yesterday, installed Anaconda today, and I have very little experience with APIs.

I downloaded the zip file from https://github.com/veox/python3-krakenex/, extracted it, then ran
python3 setup.py install within that extracted directory.
I then opened that whole extracted folder with Sublime Text 3.
Then, within open-positions.py, if I press cmd + b, I get said error message.

The full output is

raceback (most recent call last):

And for some reason, it wouldn't work anymore. Although I make sure all my keys are right, the system return {'error': ['EAPI:Invalid key']}, or {'error': ['EGeneral:Temporary Lockout']} after like 3 attempts. It was working in the morning and it doesn't anymore. It will be very much appreciated if anyone could spare a hand.

Thank you

Best,
Wolf

Hello,
When i cancel an order then there are a read operation timed out api not return result or error but the message "Request-sent" when i try to cancel again the order :(
Does it s normal ?
How can i know my order has been cancelled or if it s in pending ?
I m using python3 and the pip version of krakenex.
Thanks for your answer.

Hello, I handle the exception when a 504 error occur.

But I cannot make any request after a 504 error.
I have a "Request-sent" exception ? Where did this come from ?

Thanks !

What are you trying to achieve?

I am trying to pull the entire historic data of all OHCL using the query_public keyword, to get all the trades from the beginning of time:

# code sample
tmp = self.apiKraken.query_public("OHLC", 
			{
			    "pair": "XETHXXBT",
			    "since": "100"
			})

What do you expect to happen?

I expect to get the entire OHCL data from the beginning of time.

What happens instead?

I get the same OHCL data as if I would not try to add the 'since' parameter. In short, the result is equivalent to

tmp = self.apiKraken.query_public("OHLC", 
			{
			    "pair": "XETHXXBT",
			})

such that only a frame of the newest 700 samples is returned

# error message
I don't get an error message - This is a semantic error; From kraken's side, this should usually work.

https://github.com/veox/python3-krakenex/blob/master/krakenex/api.py#L151
When defining functions like this def query_private(self, method, req={}, conn = None): you share a single instance of the req dictionary for every call that uses the default of req.

def fn(x={}):
    return x

call1 = fn()
print(call1)
call1["a"] = "A"
call2 = fn()
print(call2)
print (call1 == call2)

If you want a fresh instance of an dictionary on every call of the function I suggest something like this.

def fn(x=None):
    if x is None:
        x = {}

Nevertheless I don't see a concrete problem raised by this in your code.

What are you trying to achieve?

During peak times large amount of http requests are failing without a specific response from Kraken server. These are intermittent problems with CloudFlare/Kraken and for some of returned http codes it should be safe to retry an operation. As each request has a unique nonce which is checked on a server, it should prevent execution of several identical requests if they get to a server despite a failed status_code.

Max number of retries should be configurable

Hi, I'm new to python and struggled following the installations. I figured out though, that using pip3 install krakenex instead of pip ... worked out. Is this normal? Has the readme to be edited?
Thanks :-)

Get order book information for ALL coins.

k.query_public('Depth', {'pair': ','.join(coin_order_list)})

What do you expect to happen?

To get order book information for ALL coins.

What happens instead?

I get an error message.

{u'error': [u'EQuery:Unknown asset pair']}

Could you please let me know if there is a way to get order book data on all currencies using one query.
Thank you in advance!

I run this code in a loop to constantly scan for opportunities with my bot. 90% of the time after 5 min my code ends in an error like this:

any ideas?

Has been brought up on Twitter. Requester failed to follow up with examples of what needs examples.

If you think something would make a good example, drop a comment (or PR).

README has claim of Python 3.3 being supported - but haven't tested that ever since 3.4 was out.

Even Debian's current stable (jessie) has 3.4 as the default for python3.

What are you trying to achieve?

I want to create a function returning a dataframe with all prices history for a list of pairs,
For example all closing prices between 2015 and 2017 for BTCUSD and ETHEUR.

1st Step is to know how to download history with dates. as parameters.

# code sample
k = krakenex.API()
k.load_key('kraken.key.txt')
ticker_1 = k.query_public('Ticker', {'pair': 'XXBTZUSD'}) #here I want to add parameters to ask for a #specific dates or period. 
ticker_1 = k.query_public('Ticker', {'pair': 'XXBTZUSD'},req(start_date, end_date, 1) )

What do you expect to happen?

#I have found this : 
th = k.query_private('TradesHistory', req(start_date, end_date, 1))
#I would like to transpose it not with tradeshistory but just ticker and dates but doing this : 
ticker_1 = k.query_public('Ticker', {'pair': 'XXBTZUSD'},req(start_date, end_date, 1) )
# does not work

What happens instead?

ticker_1 = k.query_public('Ticker', {'pair': 'XXBTZUSD'},req(start_date, end_date, 1) )
error: AttributeError: 'dict' object has no attribute '_request'

# Output of the line : 
ticker_1 = k.query_public('Ticker', {'pair': 'XXBTZUSD'})
# Am I supposed to get this : 'error': [],
# Output : 
{'error': [],
 'result': {'XXBTZUSD': {'a': ['4307.30000', '1', '1.000'],
   'b': ['4305.60000', '3', '3.000'],
   'c': ['4305.50000', '0.03977220'],
   'h': ['4399.00000', '4399.00000'],
   'l': ['4211.10000', '4180.10000'],
   'o': '4226.20000',
   'p': ['4306.30564', '4281.68920'],
   't': [8134, 13490],
   'v': ['2470.05812705', '3969.08612297']}}}

I think it would make things a lot easier if one could call API methods directly from an API() instance in Python rather than putting out using query_public() or query_private() each time. Having python methods would also help with code completion.

Has there been a decision to not include individual python methods for each API method?
If this is not the case, are there any plans to implement corresponding python methods anytime soon?
