What's on the screen at a given time

Hi MQLers,

 with a couple of trendlines on charts, am I able to do, in a possibly simple way, something like: "at 13:20:30, what trendlines can I still see"?

Simple is in the eye of the coder . . .

You need to look at all the Objects and find their datetime positions,  then you can determine if they are shown on the chart in it's current position.

Of course I was thinking in this direction, just wanted to make sure if that is the only way to achieve the same result. 

Thanks, Raptor!
