why isn't it plotting the formula? - page 2

...what should i do then. times Volume by some arbitrary large number?
 

If you change

double Momentum = iMomentum(NULL,0,9,PRICE_CLOSE,pos);

to

double Momentum = iMomentum(NULL,0,9,PRICE_CLOSE,0);

it will draw the horizontal line. It appears that iMomentum indicator has a problem with a number of bars interger assigned to a name (pos).

This is a good one for Slawa or Rosh to resolve

okay im trying to normalize, the Volume.

   double Volu += Volume[pos];
   double AvgVolu = Volu/pos;
   doube preFormula = MathPow((MACD)/Momentum,AvgVolu)

is this correct? however, i am getting unexpected semicolon error when i compile.

 
yari:
   doube preFormula = MathPow((MACD)/Momentum,AvgVolu)
is this correct?

preFormula tends either to zero or to infinity anyway depending on whether or not the first argument of MathPow() is less then 1,
unless AvgVolu is reasonably close to 1.

Have you ever heard of the properties of exponential function?

The problem in you calculations is fundamental I'm afraid.

You forgot to add semicolon after the statement above.
 

thanks its working now. after the volume was normalized with the help of others, its able to graph.

heres the thread where u can see the screenshot. if u want, i can anyone who wants to work on it hte code.

its working. However, it is not updating on each tick received. thereforei have to load it every time....very annoying. can u see why the indicator is not drawing for each tick? i'm stumped.
