Do I need an indicator for showing me the value of the trendline??

When ever I draw a trendline in metatrader charts it does not show me the current price of the trendline. How can I get that on the chart? Is there an indicator for that or do I have to change any setting from the options???

you can hold your mouse directly over the trendline and a box will appear that will show you the value at that particular point.

Otherwise, it can be done in an indicator to show you the value of the trendline.

can you or some else post this indicator pls. True the box appears but the value it shows for the trendline depends on where the mouse is on the trendline so what I'm trying to say is that it is not accurate.

I feel such an indicator is unjustifiable as it involves too much coding work/math for something so simple.
