Accessing text on screen

Here I am again.
I would like to draw a rectangle around specific bids or asks under specific conditions.
Let suppose I want to emphasize bid and ask POCs separately as shown here:
The simpler way to do it should be access specific text element and let it draw its border (i.e. text.Border = true;) but I don't know if it is possible at all access to it so: anyone has ever tried it?

Hello Al3cs,

Unfortunately there is no way to access a specific text element and draw the border for it.

Hi A13cs fwiw you can change plot colors under defined conditions. (This is probably obvious and I bet you're already doing it.)

It's not obvious for me, thank you for the hint.
I will look for more infos about it or I could draw a rectangle and anchor to bar but I never tried it before.
I will check for both, I'm new to C# so I will surely learn something useful from it.
