combination of 2 indicator

New comment
 

i wish to combine 2 indicator,

but seem not working.

 
first lesson for me in mql4 course.

what have you done...
 

just trying to combine stochastic and rvi indicator.

 

what does the character [and] [or] in mql4 ?

how to use [and] [or] in mql4 ?

then how to use it together ??
 
why cant ?
 

[and] and [or] https://book.mql4.com/basics/expressions

what do you mean by combine ? because you can attach stoch to a chart and then drag and drop RVI on to the stoch

and vice versa

:)

 

trying to combine them together,

so the indicator window will appear 4 line with stochastic and rvi function.

  
int deinit()
  {
   int    a,b,nLimit,nCountedBars,counted_bars=IndicatorCounted();
   double dValueUp,dValueDown,dNum,dDeNum;
//---- minimums counting
   a=Bars-KPeriod;
   if(counted_bars>KPeriod) a=Bars-counted_bars-1;
   while(a>=0)
      for(i=0; i<=nLimit; a++); 
      && (j=a; j<i+ExtRVIPeriod; j++);
        {
         dValueUp=((Close[j]-Open[j])+2*(Close[j+1]-Open[j+1])+2*(Close[j+2]-Open[j+2])+(Close[j+3]-Open[j+3]))/6;
         dValueDown=((High[j]-Low[j])+2*(High[j+1]-Low[j+1])+2*(High[j+2]-Low[j+2])+(High[j+3]-Low[j+3]))/6;
         dNum+=dValueUp;
         dDeNum+=dValueDown;
         dNum=0.0; 
         dDeNum=0.0;
        }
      if(dDeNum!=0.0)
         ExtRVIBuffer[i]=dNum/dDeNum;
      else
         ExtRVIBuffer[i]=dNum;   
     }
   if(counted_bars>KPeriod) i=Bars-counted_bars-1;
   while(i>=0)
     {
      double min=1000000;
      k=i+KPeriod-1;
      while(k>=i)
        {
         price=Low[k];
         if(min>price) min=price;
         k--;
        }
      LowesBuffer[i]=min;
      i--;
     }
 
what the mean of [ expression on global scope not allowed] ??
