Run asynchronously two loops to get data from bitfinex websocket and save/update the database.

Parameters:

channel : {‘book’, ‘book_raw’, ‘trades’, ‘trades_raw’}

Channel to get data, by default data will be aggregated (OHLC for ‘trades’ and reconstructed orderbook for ‘book’), add ‘_raw’ to the channel to get raw data (trade tick by tick or each orders).

‘book_raw’ and ‘trades_raw’ can be very memory expensive.
