Linked group means a grouping of windows into one symbol group. In other words, if you change a symbol in one of the linked windows, it will automatically change to the same symbol in all of the linked windows.
To set up a linked group between symbols, click on the colored square next to the window name. For your convenience, colors that you have already used for links are placed on a separate line in the upper part of the linking menu.
After choosing a color, select the same exact color in all the windows that you want to link. That’s it—the windows will be combined into one link group.
The Tiger.Trade terminal allows linking of levels plotted on the chart. If you enable the Levels option in a group of links on the DOM, then the levels will be shown on the DOM itself. In order to synchronize the levels between the chart and the DOM, select this option in the DOM link menu.
In addition, in the headers of the Chart and DOM windows, you will see includes S (Spot) and F (Futures) labels you can click to switch the instrument class. If you want to link Spot-Futures, link two widgets, select desired market types with labels, click on three dots or right click on the title bar of the widget and select Lock market type. Further when you switch instruments, the pair Spot and Futures for the corresponding instrument will be selected.
