The DOM area has four tabs, so that you can monitor and trade more than one symbol on a single Order Ticket.
The tabs are color-coded:
Red (burgundy) tab = short
Green tab = long
Black tab = working order with no position
A thermometer representing the current market standing of the symbol as well as the symbol are displayed on each tab. The thermometer gives a graphic indicator of the current market standing relative to its opening, high and low prices. It shows the High to Last (Red), Low to Last (green), and Open (yellow triangle) for that symbol for the current day. The close or last price is indicated by the change of color from red to green. If the thermometer displays all yellow, the data is not available, and you cannot trade the symbol.
The number on the right is net change. For options, the current strike price is also displayed.
To see all of the tabs, then click and drag the dotted splitter line:
