As you can see in the video, it synchronizes the movement of the chart with TimeFrame Sync v2.1. (You need to install TimeFrame Sync v2.1 on all charts you want to synchronize)

It also synchronizes scaling and time frames, and you can select which items to synchronize from the parameters.

However, there is a habit of usability, first of all, synchronization may be one-way under certain conditions. In the video, the chart on the left is the main chart and the chart on the right is the subordinate, but even if you move the chart on the right, the chart on the left may not follow correctly.

And regarding the main condition, this is "the chart that changed the parameter last" is the main, and the other charts are subordinate.

In addition, for currency pairs, synchronization can be turned on and off with parameters, and the dollar-yen and euro-dollar charts can be synchronized.
