Reader BillM commissioned me to build this swing trading study some time ago. The premise is very simple: Go long when the price breaks above the highest high from the last n days and go short when the lowest low of the last n days is broken. The study is very discreet in that the display is a single horizontal line indicating the price threshold required for the next trade reversal on the current bar. Historical price triangles remain as reference markers for previous trades. Also shown are AutoFibs and Multi-Stops as well as a mechanical trading system that I have developed and am in the final stages of testing.
