Order Book
The order book widget allows you to have display the order book of an instrument or a pair on multiple exchanges. You can either choose to display only one instrument, multiple instruments next to each other, or have an aggregated view of all the instruments for a given pair.
Usage
Use the "Instrument" button to select the instrument you want to display the book of. Write a symbol in the search box, and select either a specific instrument from an exchange, or a pair. In case you selected a pair, the widget will fetch all the order books on all the exchange the pair is traded.

Use the "Size filter" button to select the size on which to filter the trades.
