Can I Trade from the Chart

Yes, there are multiple ways to do this. The most common way to accomplish this is to use the Trade Window (accessible from the top menu: View > Trade Window) which is a panel displayed on the right hand side of the chart. From here you may place or modify existing orders. Existing orders may be viewed/modified on the chart by showing the Orders Layer (turned on by default when the Trade Window is active). The order layer is accessible from the chart tool bar. New orders may also be placed from the chart context menu (right click on the open chart area) or by clicking on the price axis, or by using the Bid/Ask Boxes.
