Datasets to power the Market Depth chart.
Both bids and asks are lists of 2-item tuples: [price, volume]

Additionally there are aggregate values provided for both sides of the book
and both quote and base currencies (in that order) under the totals key:

totals = [
[amount of quote currency in bids, amount of base currency in bids],
[amount of quote currency in asks, amount of base currency in asks],
]
