Try using this :

#property indicator_buffers 1
#property indicator_separate_window
#property indicator_color1 clrYellow

extern int ShortPeriod = 6;
extern int LongPeriod  = 100;
extern int CountBars   = 500;

double Buffer[];
int init()   { SetIndexBuffer(0,Buffer); 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 = (CountBars>0) ? MathMin(Bars-1,CountBars-1) : MathMin(Bars-counted_bars,Bars-1);

   double dev0 = iStdDev(NULL,0,LongPeriod,MODE_EMA,0,PRICE_CLOSE,0);
   for(int i=limit;i>=0;i--)
   {
      double dev = iStdDev(NULL,0,ShortPeriod,MODE_EMA,0,PRICE_CLOSE,i);
      Buffer[i]  = (dev!=0) ? dev0/dev : 0;
   }
   return(0);
}

But you know that it will repaint (regardless of what you set for CountBars - "calcperiode" in the code you posted)?

seems working, ty. What do you mean it will repaint?

Mladen Rakic 2016.11.10 16:21 #7

constantin_n:

seems working, ty. What do you mean it will repaint?

It is using standard deviation of the current bar for all the past values (the "iStdDev(NULL,0,LongPeriod,MODE_EMA,0,PRICE_CLOSE,0)" part from your code). That has two problems - issues :

Past values are calculated using de facto future standard deviation that it could not "know" in the moment when that bar was closed
As soon as a new bar is formed, all the past bars (because of the above) are rendered obsolete and must be recalculated : i.e. : all the past values are going to be repainted

In order to avoid that, you have to replace the "0" part of that standard deviation call with "i", and move it within the loop, and only then you shall have a non-repainting indicator (in that case the code would be like this - CountBars removed since there is no need to use it at all :

#property indicator_buffers 1
#property indicator_separate_window
#property indicator_color1 clrYellow

extern int ShortPeriod = 6;
extern int LongPeriod  = 100;

double Buffer[];
int init()   { SetIndexBuffer(0,Buffer); 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--)
   {
      double dev = iStdDev(NULL,0,ShortPeriod,MODE_EMA,0,PRICE_CLOSE,i);
      Buffer[i]  = (dev!=0) ? iStdDev(NULL,0,LongPeriod,MODE_EMA,0,PRICE_CLOSE,i)/dev : 0;
   }
   return(0);
}
