Re: [EquisMetaStock Group] Weekly MACD histogram

I have this formula for "slope of line".

  {Slope of Line}
Periods:=Input("Periods",5,50,10);
Slope:=((Sum(Cum(1)*P,Periods))-
(Sum(Cum(1),Periods)*Sum(P,Periods)/Periods))/
((Sum(Power(Cum(1),2),Periods))-
(Power(Sum(Cum(1),Periods),2)/Periods));
Slope;

Here's virtually the same thing applied to a 75 period Tema of CLOSE.

  {Slope of Tema}
A:=Tema(C,75);
Pds:=10;
Slope:=((Sum(Cum(1)*A,Pds))-
(Sum(Cum(1),Pds)*Sum(A,Pds)/Pds))/
((Sum(Power(Cum(1),2),Pds))-
(Power(Sum(Cum(1),Pds),2)/Pds));
Slope;

I'm unaware or who the author is but think I picked these up from the Guppy site ages ago.

Thanks Roy and Jose.   What great websites.  I pasted the formulae in and it works great.

There is a mathematical formula that gives the slope of an indicator, i.e. is a MACD line going
basically up or down?  I have seen reference to a slope of a regression line (if this is the same
thing) but nothing that could be applied to any indicator. I guess it would use a P Array
expression.

Thanks again.

  For a more basic version try this. It still uses Jose's "Calendar Week counter" for the greatest
  accuracy with any data gaps. Check it's accuracy against the canned MACD() indicator on any weekly
  periodicy chart.
