problems with ima call function

[Filippo Pozzebon]

Hi eberybody,

i 've the following problems about the return valure of the iMA function.

Here's my code, without any errors:

int OnInit()
 {
 mediaexp=iMA(NULL,0,10,0,MODE_EMA,PRICE_CLOSE);
 return(0);
 }

void OnTick()
 {
  CopyBuffer(mediaexp,0,0,3,Expmedia);
  ArraySetAsSeries(Expmedia,true);
  Print("la media è",Expmedia[0]);
 }

the iMA function return always the value 10.0 and the copybuffer doesn't work because it don't fill the buffer,

can someone help me?

thanks a lot

Please use SRC button and edit your post. Write the code completely (how big is the Expmedia variable ?), do error checking, execute ArraySetAsSeries before CopyBuffer() and not after it,

I try to execute ArraySetAsSeries before CopyBuffer()  but it doesn't work aswell...the problem that i don't understand is why the rsi ( usign the same code) is ok and work, instead of iMA!

do i'm missing something to do in the code before the Ima function?

please help me..

Sorry, I wasn't clear enough :(. This is SRC button, I'll edit your post then.

Show your declaration of Expmedia array

Show your declaration of Expmedia array

Hi,

here the declaration:

double rsival[3],Expmedia[1000];

[Slava]

Try to use dynamic array without dimension declaration

double Expmedia[];

[Filippo Pozzebon]

I try Without dimension but it return "internal error, Array out of range"

[William Roeder]

Filippo Pozzebon #: I try Without dimension but it return "internal error, Array out of range"

   ArraySetAsSeries(Expmedia,true);
   Expmedia[0]=mediaexp;

You didn't show us where you created ExpMedia[], or where you resized it. You would know that if you use the debugger.
