I am struggling to find this answer.
Suppose i draw a drawing tool on chart and set it global by "Attached to all charts" from its property. We see drawing tool immediately appear ( drawn ) on all open chart of that instrument ( quite basic to understand ). But i need to know what (internal ? ) methods are invoked to draw the drawing tool automatically on other chart apart from one on which it was manually drawn. I experimented heavily and could not found any clue and it seems even OnRender method is not invoked for this. Can any one assist me on this ?
