Help with iCustom

New comment
 

Hello.

 

I have made an Custom Indicator (SwingShow) that is working just fine.

 

Now i'm trying to make a ExpertAdvisor based on this Custom Indicator.

 

i have this code OnTick 

....

Swing = iCustom(Symbol(),PERIOD_CURRENT,"SwingShow",0,0); 

.... 

 

But when i check Swing it does not change, it keeps always the same.

 

Can anyone help please? 

 
 

Here are the Indicator Code. It determines whether we are in Asc Swing  1 or Desc Swing - 1 just that.

 

SwingShow.

 

#property indicator_separate_window
#property indicator_buffers 1       // Number of buffers
#property indicator_color1 Blue     // Color of the line

double Buf_0[];
int i, swing_inicio, swing_fim;
string swing;

int OnInit()
{  
   SetIndexBuffer(0,Buf_0); 
   SetIndexStyle (0,DRAW_HISTOGRAM,STYLE_SOLID,5);
   
   int FirstBar = iBars(NULL,0) -1;
   
   swing_inicio = FirstBar; 
   swing_fim = FirstBar;
            
   if (iClose(NULL,0,FirstBar-1) < iClose(NULL,0,FirstBar)) swing = "desc";
   else swing = "asc";
      

   return(INIT_SUCCEEDED);
}


int OnCalculate( const int rates_total, const int prev_calculated, const datetime &time[], const double &open[], const double &high[], 
                 const double &low[], const double &close[], const long &tick_volume[], const long &volume[], const int &spread[] )               
{      
      
      int x = rates_total - 1 - prev_calculated;
           
      
      for (i=x; i > 0; i--)
         
  
         if (swing == "desc")
         { 
            
            Buf_0[i] = -1;
                        
                
                  if (close[i-1] > open[swing_fim])
                  {

                      swing_inicio = swing_fim;
                                               
                      swing_fim = i-1;
                           
                      swing = "asc";
                  }

                  if (close[i-1] < close[swing_fim]) 
                  {
                      swing_fim = i-1;
                  }  
               
         }    

         else if (swing == "asc")   
         { 
            
            Buf_0[i] = 1;
            
                  if (close[i-1] < open[swing_fim])
                  {
                     
                      swing_inicio = swing_fim;
                                               
                      swing_fim = i-1;
                           
                      swing = "desc";
                  }
            
                  if (close[i-1] > close[swing_fim]) 
                  {
                      swing_fim = i-1;
                  } 
                  
         }    


return(rates_total);

 

 

Now when i call it from the EA trhought iCustom function it dosen't return the expected value. Instead it shows always a very big number like 123215......


double Swing; 

Swing = iCustom(Symbol(),PERIOD_CURRENT,"SwingShow",0,0); 


 
  1. Don't paste code
    Play video    		Please edit your post.
    For large amounts of code, attach it.
  2. You never set element zero.
    for (i=x; i > 0; i--)
   :
   Buf_0[i] = -1;
    So why would you expect to read anything from element zero?
    Swing = iCustom(Symbol(),PERIOD_CURRENT,"SwingShow",0,0);
 

Thank you very much. 

Big blunder :)
