 ## `bfxapi.DataServerWebsocket`
 
 The data-server websocket is used for retrieving large amounts of historical data from a `bfx-hf-data-server` instance. The library then takes all of the incoming historical data from the server and pushes it down the `new_trade` and `new_candle` events. For information on how to start a data-server instance please visit the repo at: https://github.com/bitfinexcom/bfx-hf-data-server
