add horizontal radical

THE end of radical can show us directly that which max high or low price point create the resistance or sustain.

in the same zone if there are so many radical created by past point indicate that the resistance or sustain zone was checked so many times  and is powerful.

And we can highlight each end of radical by bolding it or filling it with color to differentiate and directly show the start of radical.

So and we can integrate different radical to one, and show the power (times by checked) by such as “x3” .
