Lock Trading Icon in Chart Windows.

I would like an icon or the lock button to be visible in the active chart window when it is active. Preferably with a red background as it is visible in the smartDOM and as large as possible. I have built a trading keyboard with which I can lock and unlock the active chart window for trading at the touch of a button. However, I can only visually check whether trading is locked in the chart window by clicking on it with the right mouse button and activating the menu. It would be better to be able to see this in the chart windows.
