11. 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 11.1. 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 11.1, to buy MSFT at price 25.09, 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.	Figure 11.1
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, xredx for Sell, and xorangex for Short. 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. Cancel First, select how you want to cancel the open orders by clicking the drop-down button on the right of Cancel button. You can select [Cancel Last], [Cancel All], [Cancel Buys], and [Cancel Sells] (Figure 11.2). After the Cancel button changes to your desired action, just simply click on it then the open orders placed by the Market Depth window will be cancelled. Ticker The Ticker section records all the real time transactions as they take place in the market. It scrolls from top to bottom. A green Ticker means the transaction price is greater or equal to the best ask. A red Ticker means the transaction price is lower or equal to the best bid. A white Ticker means the transaction price is between the best bid/ask. To hide the Ticker section, click on the blue triangle on the left of Ticker (Figure 11.3). To activate the Ticker section, click on that blue triangle again (Figure 11.3).	Figure 11.2  Figure 11.3

In Display Settings, you can customize the color scheme of each Market Depth price layer. You can click on the Restore Defaults button to restore to default value. When you finish setting your preferences, click Apply for your change to take effect, then click OK. Click Cancel to disregard the change.	Figure 11.4
