Changelog

- 2.2.2
- Added keep_positions option, default true. BitMEX will store the last closed position for a symbol and supply it as a position. If you don't want an empty position in your book, set keep_positions: false in your options and only active positions will be monitored.
- 2.2.1
- Added keep_liquidations along with liquidation_size options to keep liquidation data from deleting shortly after received.
- Bug Fix: Liquidations weren't accessable in the book.
- 2.2.0
- Updated to work with bitmex-socket ^3.0.0
- Changed config settings, object now accepts a single object with the options chat_size, trade_size and quote_size to limit the size of these tables. { chat_size: 1000, quote_size: 1000, trade_size: 1000000 } is the default setting.
- Now allows for multiple sockets. Add a socket on creation new BitmexBook(socket, options) or add them after creation book.listen(socket1, socket2)
- Bug Fix: Table trimming was a mess. Refactored it. Decidedly works now.
- Bug Fix: Empty orders weren't being cleared from the order table.
- Added DOCS.md
- 2.1.1
- Bug Fix: Unsubscribing from a channel won't drop the whole table. eg unsubscribe('trade:XBTUSD') no longer drops the full trade table.
- Bug Fix: fetch() now checks the table exists before attempting to filter it.
- 2.1.0
- Bug Fix: updates() were reading from the data array object, not the item within the array.
- Book.fetch() now consistently returns an array.
- Added getter for Book.stream. book.stream can now be used to get the BitmexStream object created by the BitmexSocket object on new_stream().
- 2.0.0
- Complete rewrite.
