Next, modify the classname of the provider (ideally align this with the Filename).
The base-class provides an instance of the exchange (`self._exchange`) the pairlist manager (`self._pairlistmanager`), as well as the main configuration (`self._config`) and the pairlist dedicated configuration (`self._pairlistconfig`).
The base-class provides an instance of the exchange (`self._exchange`) the pairlist manager (`self._pairlistmanager`), as well as the main configuration (`self._config`), the pairlist dedicated configuration (`self._pairlistconfig`) and the absolute position within the list of pairlists.
```python
self._freqtrade = freqtrade
self._exchange = exchange
self._pairlistmanager = pairlistmanager
self._config = config
self._whitelist = self._config['exchange']['pair_whitelist']
self._blacklist = self._config['exchange'].get('pair_blacklist', [])
self._pairlistconfig = pairlistconfig
self._pairlist_pos = pairlist_pos
```
Now, let's step through the methods which require actions:
