 *
 * The following events are emitted if standardMessages is false:
 *   bitfinex-ticker: BitfinexTickerMessage
 *   bitfinex-orderbook-snapshot: BitfinexOrderbookSnapshot
 *   bitfinex-orderbook-update: BitfinexOrderMessage
 *   bitfinex-trade-snapshot: BitfinexTradeSnapshot
 *   bitfinex-trade-update: BitfinexTradeMessage
 *
 * The following operational messages are also emitted
