Re: [amibroker] How to calculate a slope % with Rsquared without a loop?

["Louis P." <rockprog80@xxxxxxxxx>]

Hi,

Linear function is my big problem.  I'm so weak using that.  What is the difference between using this and doing it the other way?

BTW, how would you set the number of bars in the current:

HHVBars(Var,period); // Find number of bars - distance from HHV to current bar

%slope = ((Highest high - currentclose) / Highest high) / number of bars * 100;

Thanks,

Louis

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
