Thanks, @ericsomdahl are you maintaining the project?

@bitfag still here -- just slow to get around at the holiday season. I am ok with this fix but the build is broken due to the new USD markets added recently.

I can get to the fix for the build once my holiday starts, in a few days. in the meantime I will merge this knowing that the pypy build will not propagate out.

I'm still getting the INVALID_SIGNATURE with API 2.0 even with @forgetso 's fix in the latest version of python-bittrex.

Am I doing something wrong?

It seems like the issue is that I'm using windows. Works fine on linux

[forgetso]

@brotolisk Unfortunately, I don't have windows to check this out but glad you figured it out.

Hi, thank you guys a lot for keeping this repo up to date!! Unfortunately I am still getting the INVALID_SIGNATURE with API 2.0. Even with the latest fix and on Python 3.6 and 2.7. I use a brand new API-key & secret with all permissions. My test code would look like this:

from bittrex.bittrex import Bittrex, API_V2_0
my_bittrex = Bittrex('<MY API KEY>', '<MY SECRET>', api_version=API_V2_0) 
result = my_bittrex.trade_sell('BTC-ADX', 'LIMIT', 50.0, 0.001, 'GOOD_TIL_CANCELLED', 'NONE', 0)
print(result)

My OS is Ubuntu 18.04 Am I doing something wrong and is the fix still working for you guys?

[bitphage]

@Ben0n I have no problems on API v1.1

[Ben0n]

@bitfag thanks for your reply! API v1.1 is working fine for me too, but since I want to place a stop-loss order via the API I would need to use the API v2.0 Is API v2.0 working for you too?

[bitphage]

@Ben0n can't say anything about 2.0, I'm sticking to v1.1 as officially supported.

[forgetso]

@Ben0n Try using

my_bittrex.buy_limit(market=self.trade_pair, quantity=volume, rate=price)

but the equivalent for sell which is .sell_limit.

[forgetso]

@ericsomdahl @Ben0n Sincere apologies, it seems like I had falsely attributed the disappearance of INVALID_SIGNATURE in the response to my change to python-bittrex. However, it seems that buy_limit works in python3 but trade_buy does not.

@ericsomdahl you may wish to revert this change as it effectively does nothing.

I have the same problem here. Want to use API 2.0 but I keep getting INVALID_SIGNATURE errors.

My setup:

python --version # Python 2.7.10 pip show requests # Version: 2.21.0 pip show certifi # Version: 2018.11.29 pip show idna # Version: 2.8 pip show urllib3 # Version: 1.24.1 pip show python-bittrex # Version: 0.3.0

Testing with python3 (Python 3.7.0) shows no difference (the packages are of the same versions).

I also tried different python versions using docker images - to no avail. Also tried older versions of the above packages, no change.

Is there anyone for whom API 2.0 calls still work? Could you maybe post your output of above versions just to rule out version problems?

Or any other ideas why API 2.0 does not work?

my test code:

from bittrex.bittrex import Bittrex, API_V2_0

my_bittrex = Bittrex('apikey','secret', api_version=API_V2_0)  # or defaulting to v1.1 as Bittrex(None, None)
print(my_bittrex.get_order_history('BTC-ETH'))
print(my_bittrex.trade_sell('BTC-ETH', 'LIMIT', 0.0001, 0.00001, 'IMMEDIATE_OR_CANCEL', 'NONE', 1.0))
