This is a concept that I have been playing with to make a manual trend line that has more then just two connecting dots but that has sequential data connected on every bar between the beginning an the end point that can then be used to determine a break of trend or a bounce.
This is added in a few simple steps 1) add the indicator to your chart 2) set the x_1 time bar 3) set the y_1 price 4) set the x_2 time bar 5) set the y_2 price 6) check the table that calculated the run value and enter that value in the settings box in the "Run" input box
