Doubt in OnCalculate

 

I'm trying to create a new indicator that calculates the sum of a array (matrix of 5 symbols with correlation) and divides by a specified number.

The calculation is correct, but i'm having problems with the indicator plot. Probably in the OnCalculate part.

i want the indicator look like a moving average....  

Here is the code:

//+------------------------------------------------------------------+
//|IBOV calculation                                                  |
//+------------------------------------------------------------------+
#property indicator_buffers 1
#property indicator_plots   1
#property indicator_separate_window

#property indicator_type1   DRAW_LINE
#property indicator_label1  "IBOV"
#property indicator_color1  clrMagenta
#property indicator_style1  STYLE_SOLID
#property indicator_width1  1

//--- matrix
double   matrix[5][1];

//--- indicator buffers
double   AVXT[];

//--- global variable
double   constant = 2746.9902;
int pos;

//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int OnInit()
{
//--- indicator buffers mapping
   IndicatorSetInteger(INDICATOR_DIGITS,2);
   SetIndexBuffer(0,AVXT,INDICATOR_DATA);
   
//--- sets first bar from what indicator will be drawn
//   PlotIndexSetInteger(0,PLOT_DRAW_BEGIN,0);
   
//--- name for DataWindow and indicator subwindow label
   string short_name="AVXT";
   IndicatorSetString(INDICATOR_SHORTNAME,short_name);
   PlotIndexSetString(0,PLOT_LABEL,short_name);
   
//--- Set AVXT as time series
   ArraySetAsSeries(AVXT,true);

   return(INIT_SUCCEEDED);
}
   
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |                                                                  |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const int begin,
                const double &price[])
{
matrix[ 0 ][0]=   4320157092 * (SymbolInfoDouble("Symbol1",SYMBOL_LAST));
matrix[ 1 ][0]=   2035474854 * (SymbolInfoDouble("Symbol2",SYMBOL_LAST));
matrix[ 2 ][0]=   1226268476 * (SymbolInfoDouble("Symbol3",SYMBOL_LAST));
matrix[ 3 ][0]=   629085664  * (SymbolInfoDouble("Symbol4",SYMBOL_LAST));
matrix[ 4 ][0]=   3229206347 * (SymbolInfoDouble("Symbol5",SYMBOL_LAST));


//--- starting calculation
   if(prev_calculated>1) pos=prev_calculated-1;
   else pos=0;
      
//--- main cycle   
   for(int i=pos;i<rates_total && !IsStopped();i++)   AVXT[i] = sum()/constant;
      
//--- return value of prev_calculated for next call
   return(rates_total);
}

//+------------------------------------------------------------------+
//|Calculate Sum of indicator                                        |
//+------------------------------------------------------------------+
double sum () 
{
//--- variables
   double sum_value=0.0;  
   
//--- calcualte sum_value
   for(int a=0;a<5 && !IsStopped();a++)  sum_value += matrix[a][0];   
     
//--- return calculated value          
   return (sum_value);   
}
 
santosphm: , but i'm having problems

"Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless.

There are no mind readers here and our crystal balls are cracked.

 
As global variable you declare matriX but in OnCalculate you try to use matriZ. I can see where is declared array matriZ. When compile program compilator need to warn it for this.

when i pasted here, i translated and forgot to change this, but thanks. 

The error that occurs is: The indicator line is straight, it dosn't change with the close price, like the moving average. 

the pink is my indicator and the red is the moving average.

Sorry, 

The error that occurs is: The indicator line is straight, it dosn't change with the close price, like the moving average for example .

I think the problem is how to transform it on a time series. The previous data is the same as the current data.

That is exactly what it should do. No problem. PICNIC
AVXT[i] = sum()/constant;
Both sum and constant do not depend on i.

It is my first attempt to create an indicator

Any ideia how can i change that, now that you understood my intencion with this indicator?

  2. I have no idea what your intention is. Decide what you want to display, change your buffer assignment to that.
