In EdgeProX, you are able to place trades in multiple different ways. One of the default settings regarding placing orders is trading directly from the chart Price Axis.  This setting can be toggled off and on following the below steps. 

If Price Axis Trading is enabled, you will notice that when hovering your mouse over the Price Axis it will change to a red or blue cross hair depending on where you are placing the order. If you double click on the price axis, you will place a buy or sell limit order depending on whether your mouse is above or below market. 

You can toggle this setting by going to the "Settings" tab, or by clicking Configure > Settings.  Navigate to the "Orders" tab then configuring the settings to your preferences from this point. 

            

The below image will show you how to turn off price axis trading. This window is where you can edit anything to do with submitting orders via price axis and alerts regarding orders.
