The circular versions of each broker and the same broker may be slightly different, but that's only because the locations are different and the menus are basically the same. Wait patiently for the menu command.

Find "Custom Variety", select "Portfolio Variety Management" in the new window, select "Add Variety" in the new window, and fill in as required. The important place is the "weighted type" in the red box. It is suggested that according to your own capital ratio, if all stocks have the same capital, you should choose the same weight. Then add the stock of your choice and press OK.

In the stock interface, press the "variety code" you fill in to get the index chart.
