You can also use linearray to draw a stright line from HHV to current point. Look up LinearReg function

    Try this:

HHV(Var,period); // find value of highest high

    HHVBars(Var,period); // Find number of bars - distance from HHV to
    current bar
    %slope = ((Highest high - currentclose) / Highest high) / number
    of bars * 100;

You may choose to define slope in a different way, but this is the

    basic structure

        Hi,

        Thanks for your response.  I should have said I want to
        calculate a slope from a high point; I'd like to get a smooth
        slope from a HHV... How would you do that?

        Thanks a lot!

            %slope = (variable - Ref(Variable,-x) ) / Ref(Variable,-x)
            * 100;

                Hi,

                I was wondering how to calculate the % of a slope
                without doing any loop.  Anybody has any idea?

                Thanks,

                Louis
