This is a simple line tool that can give you active feedback based on the closing price.
It is intended for a live chart whose ticker is not changed by the user every 10 minutes, like a general overview of an asset in a higher time frame.
What can it provide:
Price difference from the price to the line
Price at the current collision point
How to use it:
When opened, it requests 2 input points from you.
After you set these 2 points, it will set the "Active Line" for you, like the normal TV line.
One thing to know is that you can't place into the future, so "extend" is always on by default.
and as always, have fun trading the assets up and down :-)
