New version bittrex not working

[hunsnowboarder]

I had a code running without any problems. I updated the bittrex.py file and now I get an error:

Traceback (most recent call last): File "C:/Lori/Adam/bitcoin/cryptoarb/rsi_bot.py", line 50, in balance_btc = xchange.fetch_balance()['BTC']['total'] File "C:\Python27\lib\site-packages\ccxt\bittrex.py", line 201, in fetch_balance response = self.accountGetBalances() File "C:\Python27\lib\site-packages\ccxt\bittrex.py", line 616, in request response = self.fetch2(path, api, method, params, headers, body) File "C:\Python27\lib\site-packages\ccxt\base\exchange.py", line 258, in fetch2 request = self.sign(path, api, method, params, headers, body) File "C:\Python27\lib\site-packages\ccxt\bittrex.py", line 584, in sign self.check_required_credentials() AttributeError: 'bittrex' object has no attribute 'check_required_credentials'

OS: Win7
Programming Language: Python 2.7
CCXT version: 10.477
Exchange: Bittrex
Method: fetch_ohlcv()

This is my code... so far it worked allright, now it wont work because of the error message. What is wrong? Thank you in advance!

            xchange = ccxt.bittrex({'proxy': currentProxy,

               print 'waiting'
               time.sleep(30)

    # -----------------------------------------------
    # check if we are in BTC and have no open orders

    balance_btc = xchange.fetch_balance()['BTC']['total']

Does this work:

import ccxt
exchange = ccxt.bittrex({
    'apiKey': 'YOUR_API_KEY',
    'secret': 'YOUR_SECRET',
})
print(exchange.fetch_balance()['BTC']['total'])

?

Yes, it solved my problem!

Thank you very much for your help!

[kroitor]

@hunsnowboarder would be cool if you could reply to #962 ;)

[hunsnowboarder]

Yes, I will now. Thank you!

[hunsnowboarder]

I dont understand. The code you just pasted here works with jupyter notebook, but it produces error with pycharm. They both use python2.7.

What could be the problem?

Thank you

@hunsnowboarder what's the version of ccxt in pycharm? ccxt.__version__ = ?

[hunsnowboarder]

Sorry for my late reply. I had very strange issues and finally figured out what the problem was. I did not update ccxt for a while now only some of the exchanges.

So I did a thorough update of everything and now it works like a charm. Thank you again for your continuous support and help! Have a happy new year!
