I can't connect to Gemini Broker using BT and ccxt for live trading.

[kzbt]

Hello,

I would like to connect Backtrader on Gemini using CCXT but I can't figure it out.

Here is my code:

Python 3.6.9 (default, Oct  8 2020, 12:12:24) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from __future__ import(absolute_import, division, print_function, unicode_literals)
>>> from datetime import datetime, timedelta
>>> import backtrader as bt
>>> from backtrader import cerebro
>>> import time
>>> 
>>> config = {'urls': {'api': 'https://api.sandbox.gemini.com'},
...                          'apiKey': 'master-xxxxxxxxxxxxxxxxxxxxxxxxxxx',
...                          'secret': 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
...                          'nonce': lambda: str(int(time.time() * 1000))
...                         }
>>> broker = bt.brokers.CCXTBroker(exchange='gemini',
...                                    currency='USD', config=config)
>>> 
>>> cerebro.setbroker(broker)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'backtrader.cerebro' has no attribute 'setbroker'

but when I check my file .local/lib/python3.6/site-packages/backtrader/cerebro.py I can see

    def setbroker(self, broker):
        '''
        Sets a specific ``broker`` instance for this strategy, replacing the


        one inherited from cerebro.
        '''
        self._broker = broker
        broker.cerebro = self
        return broker

When I try to connect directly without CCXT and Cerebro I have no issue.

Does anyone have any Idea?

Also I would like know how the class gemini get generated ? maybe if I can have working sample of how to config gemini or similar broker this would help me. I'm not having issue of getting the feed.
