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

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

Hi,

I'm kind of really new to linear functions and things like that.  I thought Rsquared was necessary to calculate how steep is a slope.  I want to calculate how smooth is a slope from a high point.  I will try your suggestion Ara, but this is kind of new stuff for me.

Thanks,

Louis

How does the 'Rsquared' from the subject, come into this discussion?

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
