I have opend about 20 currency pairs and got them arranged next to each other with the "Arrange windows as non overlapping tiles " button.
The problem is that i have some indicators on all of this charts but they don't resize with the window. They stay as big within the chart window as the window was never resized.
IF you mean things like text labels stay the same size, that is because font sizes do not resize according to the window size. They are so many pixels according to your total screen resolution.
