If you don't particularly like the yellow H1 and L1 lines running across the whole screen, you can add this function at the very top of your code

function Howlong(indicator,Length)
// a length of 0 will place a dot at the last bar
{

Start = LastValue( Cum(1)-Length) ==Cum(1);
Start2 =  Cum(Start) ==1;
x = ValueWhen(Start2 ,indicator,1) ;
return x;
}

and change the plot lines to:
Plot(Howlong(H1,Lookback + Shift), "H1", colorYellow);
Plot(Howlong(L1,Lookback + Shift), "L1", colorYellow);


Best Regards
Rick

This is a great formula i hope you don't mind that i uploaded it to the formula library:

I have attached more charts & hope this might help.  Our market moves 5% max up or down daily, I made the LOOKBACK & SHIFT narrow because I wanted to catch those fast rallies, buying when prices hit support L1 & selling when it hits H1.
