10. Market Depth  To bring up the Market Depth window in Fortex, go to the menu bar Market -> Market Depth or click on the toolbar icon. When you see the Market Depth window pop up, please enter or select your stock symbol in the Symbol field on the upper left hand corner. The window will then load streaming Market Depth market information as Figure 10.1. A Market Depth window includes the following components: the tool bar and Quick Quote Panel on the top, the Market Depth Bid/Ask Panels in the middle, the Order Entry panel at the bottom, and the Ticker section on the right. Order Entry To enter an order in the Market Depth window, you just need to perform a simple point and click action. To populate the right information into your order entry box, you just need to double-click on an entry in either the bid or ask panel. After that, you can click on the action button Buy Sell Short to specify your desired action and submit the order. For example, in Figure 10.1, to buy EUR/USD at price 1.38465, one just needs to double-click on the best Ask entry in the ask panel, then the desired order information is loaded into the order entry box; another click on the action button will submit the order.

Please know that the color of the action buttons and the fields of the order entry box will change according to the action specified; xgreenx for Buy and xredx for Sell. The right color will be highlighted for about half of a second and then get refreshed. This design is to raise traders’ awareness of the action being taken.

You can select [Cancel Last], [Cancel All], [Cancel Buys], and [Cancel Sells] (Figure 10.2).
