BUY LIMIT ORDER

At the moment cannot give the currency_pair param. For now we can only trade BTC/USD.

Still a couple of API calls which are supported but aren't listed in the README.md documentation. I've been working in the same order as the API documentation page so it's everything after the last documented one to go.

When trying to do 'from bistampy import api' i get 'ImportError: No module named calls'

A simple fix for this was to simply change the first line in api.py from 'import calls' to 'from . import calls'

maybe it's just me but:
from bitstampy import api
c='999999'
k='xXx'
s=b'xXx'
api.account_balance(c, k, s)

and I get the error:
TypeError: Unicode-objects must be encoded before hashing
on pyhton 3.4

c = '12345'
k = 'xxxxx'
s = 'yyyyy'
api.account_balance(c, k, s)

Changed key to bytes :

TypeError: must be str, not bytes

I am rather confused. Could you please clarify the argument types to use for client_id, api_key, api_secret ? Thanks

Hi,
Tried to run the code on python3, and got this stacktrace. It appears to be a python3 compatability issue - the code runs perfectly on python2
Thankyou

Does this library support python3?

Hi Jack

Thanks for the API!

I'm trying to do a buy limit order and I'm getting an error. Is this a problem with Bitstampy or just something that I'm doing wrong... sorry to post this here but I could not find your email address.

bitstamp.buy_limit_order(c, k, s, 0.01, ask * 1.10)

Traceback (most recent call last):
File "/Users/daniel/bitcoin/coinduit/bank/bank.py", line 17, in
bitstamp.buy_limit_order(c, k, s, 0.01, ask * 1.10)

return super(APIPrivateCall, self).call(**params)
File "/Library/Python/2.7/site-packages/bitstampy/calls.py", line 57, in call
raise APIError(response['error'])
APIError: Invalid nonce

Is there something I need to do to set the nonce?
