southxchange & bleutrade fetch_balance error (ccxt v. 1.9.174, Python 2.7)

[PhinixPhire]

The fetch_balance() function in southxchange and bleutrade seems to result in this error:

Traceback (most recent call last):
  File "C:\xampp\cgi-bin\TheChankReport.py", line 71, in <module>
    fetch_wallet()
  File "C:\xampp\cgi-bin\TheChankReport.py", line 22, in fetch_wallet
    balance = x.fetch_balance()
  File "C:\Python27\lib\site-packages\ccxt\exchanges.py", line 5482, in fetch_balance
    account['used'] = balance['Balance'] - balance['Available']
TypeError: unsupported operand type(s) for -: 'unicode' and 'unicode'

I have bittrex, anxpro and hitbtc working with the same code.

@PhinixPhire got it, will fix it... Unfortunately, Python is very sensitive... No problem, just a sec.

I did a fix for bleutrade, should be ready soon. In the meantime, can you please paste verbose output for the error you were getting with southxchange?

@PhinixPhire sorry, but File "C:\Python27\lib\site-packages\ccxt\exchanges.py", line 5500, in fetch_balance is the location of bleutrade, not southxchange... I can't find any problem with southxchange currently... In fact their calls should look completely different, so your output does not seem to be the output for southxchange... Are you sure that your code calls from southxchange correspond to that verbose output?

[PhinixPhire]

Ohhh... I see what's happening. southxchange is working, but I have no balance, so it provides no output aside from the verbose pasted above.

bleutrade is next in the exchange_list array, so it errors out and I mistakenly interpreted it as southxchange's error. Then I tested bleutrade in another script and found it to have the error.

Sorry for the confusion!

[kroitor]

Oh, now I see. No problem, that happens. My advice is: put an explicit line "empty balance" there instead of nothing, when the balance is empty, following that rule for all undefined variables will save you hours of debugging, really. ;)

So, I guess, the only problem is bleutrade and it should be fixed by the upcoming build in 5 minutes, right? Let me know if it works for you or not, please. )

[PhinixPhire]

Yep, that should be it. I'll confirm if working as soon as the update comes through. Thank You so much!

[kroitor]

It's there, will stand by to hear from you.

[PhinixPhire]

Working great! I appreciate the help, as always.
