When you enter a Futures or Options contract screen, if you swipe your finger to the right, you will access a different view for the contract, that shows the market depth of the contract, with 5 bid/ask places.

At the top of every contract screen, you will see some dots indicating in which view you are currently at, and to which side you should swipe to see other views. All contracts have their related Twitter conversation when swiping left, and Futures and Forex have a daily chart view when swiping right.
