The Account Summary module displays the account status information. It includes the positions, available funds, margin size, and available balance (NAV).
There are separate sections for instrument types (Cash, Futures, Options, etc.). Each section consist of open positions with their quantity, prices, P&L (including the projected daily P&L) and other values.
By default, the Account Summary shows the real-time data.
By pressing the 
button you can choose a historic time period.
If you hover over a price of an asset, you will see a hint with its current price and the exact time when this price was retrieved.
