Objects drawn from the PRT platform are mirrored in lower TF’s, when an option has been ticked, but lines drawn by indicators are not, the same as MA’s or Pivots and so on….
You need to add the same indicator to any different chart you want to use.
If you draw a line on a higher TF and you can see them in lower TF’s that is because that option I was talking about is set, maybe by default.
It’s an option you can find in the general options of the platform.
