SetIndexEmptyValue(0,0.0); - am I right: it's needed only once?

New comment
 

Hi,

it's just a request for a confirmation.

if I write in my indicator only once in the init() function:

SetIndexBuffer(0,buffer0); 
SetIndexEmptyValue(0,0.0);

then at every new bar the buffer0[0] ist set to 0.0 automatically and NOT to EMPTY_VALUE?

Thanks in advance,

Gooly

 
yes
 

THANKS!

Gooly

 

But it seems not to be true!??

int init() {
..
   SetIndexBuffer(0,buffer0); 
   SetIndexEmptyValue(0,0.0);
..
}

int start() {
...
if ( buffer0[0] == EMPTY_VALUE ) {
   Print(TimeToStr(TimeCurrent(),TIME_SECONDS),"  eCkeck: buffer0[0] = ",DoubleToStr(buffer0[0],0)," = ",EMPTY_VALUE);
}
..}

and I get once and a while:

2013.05.17 17:15:28    eCheck EURUSD,M15: 18:15:01  eCheck: buffer0[0] = 2147483647 = 2147483647
2013.05.17 17:15:28    eCheck EURUSD,M5:   18:15:01  eCheck: buffer0[0] = 2147483647 = 2147483647

What went wrong?

Is it a bug?

Is it an indicator? Show the the code above init.
 

ok here the beginning of the iondicator:

#property indicator_separate_window
#property indicator_buffers 5
#property indicator_color1 Red 
#property indicator_color2 DodgerBlue
#property indicator_color3 LawnGreen
#property indicator_color4 White
#property indicator_color5 Gray

// User input
extern int              LongMA_PER=0;
extern int              ShortMA_PER=13;

int MA_Shift=0,minPer=0;

// Buffers
double buffer0[];
double buffer1[];  // 
double buffer2[];  // 
double buffer4[];  // 
double buffer3[];  // 
//----
int ExtCountedBars=0;
int lastcolor=0;
string nameIndi;

double   v, cMA_Short, prB,cMA_Long, Long_PRb;

//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int init()  {
   int    draw_begin;

   // indicator buffers mapping, drawing settings and Shift
   // Histogram upArrow Green
   SetIndexBuffer(0,buffer0); 
   SetIndexBuffer(1,buffer1);
   SetIndexBuffer(2,buffer2); 
   SetIndexBuffer(3,buffer3);
   SetIndexBuffer(4,buffer4);

   SetIndexStyle(0,DRAW_HISTOGRAM);

   SetIndexEmptyValue(0,0.0);
   SetIndexEmptyValue(1,0.0);
   SetIndexEmptyValue(2,0.0);

   
   // Histogram downArrow Red
   SetIndexStyle(1,DRAW_HISTOGRAM);

   // Histogram upArrow Green
   SetIndexStyle(2,DRAW_HISTOGRAM);

   // Moving average line white
   SetIndexStyle(3,DRAW_LINE);

   // Moving average line white
   SetIndexStyle(4,DRAW_LINE);


        if ( Period() != 1 )
           IndicatorDigits(0);
        else
           IndicatorDigits(2);

   if(ShortMA_PER<2) ShortMA_PER = 2;
   draw_begin=ShortMA_PER-1;

   SetIndexDrawBegin(0,draw_begin);
   
   return(0);
}

something wrong?

This indicator is running on M1, M5 and M15 but (now) only M15 is in troubles..???
