You can synchronize your charts in the multi-chart layout by clicking on the "Select Layout" button on your main toolbar and choosing which elements you would like to synchronize. With this menu you have the ability to synchronize the following elements of your chart: symbol, crosshair, interval, time and date range. For example, if you would like to use the same symbol for both charts, then you need to choose "Symbol".
To enable synchronization of drawing objects, open the multichart mode in the Select Layout menu.
Now turn on the synchronization of drawing objects using the button on the left panel.
Please note that drawings can only be synchronized on charts that contain the same symbol.
