My friend has the Bv/Sv volume information on the MoonBot terminal chart on the left and I have it on the right, how can I move it to the left too?

In MoonBot on the tab Settings – User Interface there is a setting “Chart info in right corner”, if it is checked, then the display of buy volume/sell volume on the chart for a given time will be on the right, if it is not checked, then it will be displayed on the left. In your case, you need to uncheck this setting.
