Viewing the orderbook

The orderbook view is a constantly updated, real-time list of all outstanding buy and sell [limit] orders for the selected instrument, organized by total USD price (price of instrument X quantity of instrument).

The order book is presented in two sections, identified by red or green colored bars. The top half with red-colored bars are Sell orders, or asks. The bottom half with green-colored bars are Buy orders, or bids.

Each row in the orderbook contains price levels and the number of contracts (Size) for each corresponding price. The Total column shows a cumulative count of contracts from the middle of the order book to each price level.
