code to access the indicator buffer - help me please

New comment
 

Hello and sorry for my english. I want to add a pointer to an EA and I need to add code to access the pointer buffer. I include the indicator below

int init()

{

   SetIndexBuffer(0,lag);

   string shortName = "LaguerreMA";

   IndicatorShortName (shortName);

   return(0);

}


int deinit() { return(0); }

//+------------------------------------------------------------------

//|                                                                  

//+------------------------------------------------------------------

int start()

{

   int counted_bars=IndicatorCounted();

      if(counted_bars<0) return(-1);

      if(counted_bars>0) counted_bars--;

         int limit = MathMin(Bars - counted_bars,Bars-1);

   //

     for(int i = limit; i >= 0 ; i--) lag[i] = LaGuerre(iMA(NULL,0,1,0,MODE_SMA,Price,i),Gamma,i,0);

   return(0);

}

//+------------------------------------------------------------------

//|                                                                  

//+------------------------------------------------------------------

//

double workLag[][4];

double LaGuerre(double price, double gamma, int i, int instanceNo=0)

{

   if (ArrayRange(workLag,0)!=Bars) ArrayResize(workLag,Bars); i=Bars-i-1; instanceNo*=4;


   //

    workLag[i][instanceNo+0] = (1.0 - gamma)*price                                          + gamma*workLag[i-1][instanceNo+0];

workLag[i][instanceNo+1] = -gamma*workLag[i][instanceNo+0] + workLag[i-1][instanceNo+0] + gamma*workLag[i-1][instanceNo+1];

workLag[i][instanceNo+2] = -gamma*workLag[i][instanceNo+1] + workLag[i-1][instanceNo+1] + gamma*workLag[i-1][instanceNo+2];

workLag[i][instanceNo+3] = -gamma*workLag[i][instanceNo+2] + workLag[i-1][instanceNo+2] + gamma*workLag[i-1][instanceNo+3];

   //

   

   return((workLag[i][instanceNo+0]+2.0*workLag[i][instanceNo+1]+2.0*workLag[i][instanceNo+2]+workLag[i][instanceNo+3])/6.0);

}


Please let me know where to look for this information in this code? I added such a path but EA does not read the data and the results are 0


res = iCustom (NULL, 0, "LaGuerre", MODE_SMA, Price, Gamma, buf, pos);


Where can I learn how to read the path to the buffer code in pointers?

I am grateful for any help.

    No such thing. You read the buffer(s) with iCustom. 

  3. 
//                          
extern double Gamma  = 0.85;
extern int    Price = 0;
double lag[];
    		 
    res = iCustom (NULL, 0, "LaGuerre", 
MODE_SMA, 
Price, 
Gamma, 
buf, pos);
    Your indicator only has two parameters, not three. It has only one buffer (buf had better be zero.)

Thank you very much for help. I will learn :-)
the record should look like
res = iCustom (NULL, 0, "LaGuerre", Price, Gamma, buf, pos); ?
Yours sincerely

Please only post in English on the forum.

I have edited your post and used the site's translation tool this time.

You will say that you will learn but
