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 Panel or DOM Panel) 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 Order tab (turned on by default when the Trade Panel is active). The order layer is accessible from the chart tool bar.

New orders may also be placed by clicking on the price axis > Trade, or by using the Buy/Sell boxes ( right click on the chart > Chart Settings > Labels tab > Add the buttons).
