Hi

Has anyone read Trading By The Book by Joe Ross before? There is one portion page 238 where he talks about LEDGE where it is just a breakout system



However, I would like to create a Metastock formula to draw in the Lines of the High of the ledge and Low of the ledge so that i can scan through charts faster. Please assist.

How can I create a formula that draws a line when:



The high of a Price Bar matches the high of another price bar to a Maximum of 10 days ago.

and Vice Versa for the Low when it matches another low of a price bar.



Thank you
