[rightx2]

My ticker list : ['BTC-ZCL', 'BTC-NEO', 'BTC-BCPT', 'BTC-ADA', 'BTC-ETH', 'BTC-ETC', 'BTC-OMG', 'BTC-LTC', 'BTC-RDD', 'BTC-XRP', 'BTC-XVG', 'BTC-BCC', 'BTC-XLM', 'BTC-BITB', 'BTC-SC', 'BTC-XMR', 'BTC-NBT', 'BTC-LSK', 'BTC-DOGE', 'BTC-MEME', 'ETH-NEO', 'ETH-ADA', 'ETH-OMG', 'ETH-XRP', 'ETH-WAX', 'USDT-BTC', 'USDT-NEO', 'USDT-ETH', 'USDT-LTC', 'USDT-ETC']

When I execute my code:

ETH-NEO  is wrong

During handling of the above exception, another exception occurred:

I added code for debuging in the library (line number 995):

 982     def _transfer_backorder_queue2(self, ticker, snapshot):
 983         confirmed = False
 984         sub = self.tickers.list[ticker][SUB_TYPE_ORDERBOOK]
 985         q = sub['InternalQueue']
 986         q2 = queue.Queue()
 987         while True:
 988             try:
 989                 e = q.get(False)
 990                 q2.put(e)
 991             except queue.Empty:
 992                 sub['InternalQueue'] = q2
 993                 return confirmed
 994             except AttributeError:
 995                 print(ticker, " is wrong")
 996                 raise NotImplementedError('Please report error to '
 997                                           'https://github.com/slazarov/python-bittrex-websocket, '
 998                                           'Error:_transfer_backorder_queue:AttributeError')
 999             else:
1000                 if self._confirm_order_book(snapshot, e):
1001                     confirmed = True
1002                 q.task_done()

If you see the error log again, there is a log, "ETH-NEO is wrong".

Why does this happen?

I still used 0.0.6.4 but it occured 0.0.7.0, too !

(Only difference is whether program STOP or not due to the error. )

I have an idea about what’s causing it and will try to fix it this week. I actually posted in a the other issue by mistake, so do you get this after reconnection?

[slazarov]

Closing issue since the code has been entirely rewritten, hence it's not applicable.
