I have tried the search function but I dont know how to word it. 

 

 I want to load the previous 5 bars into an array for calculations later on in the program. I have the below so far but it does not work. So the data should be collected at the start of the new bar. These arrays have sent my head into a spin, when I hit debug it keeps saying array out of range.

 

If I get this working how do I then compare the data values loaded. ie Price closed outside of the bollinger bands? 

ArraySetAsSeries(arrayBBLOW,true);
ArrayFree(arrayBBLOW);

for(int l = current + 1; l < 5; l++)
          {   
      arrayBBLOW[l] = iBands(NULL,0,20,2.5,0,PRICE_CLOSE,2, l);
          }
 
/////////////////// Bollinger Bands High ///////////////////


  
ArraySetAsSeries(arrayBBHIGH, true);
ArrayFree(arrayBBHIGH); 

for(int h = current + 1; h < 5; h++)
          {   
      arrayBBLOW[l] = iBands(NULL,0,20,2.5,0,PRICE_CLOSE,1, h);
          }   
   
   
////////////////// Bar Close ///////////////////////////////////////////

   
ArraySetAsSeries(arrayclose,true);
ArrayFree(arrayclose);

for(int c = current + 1; c < 5; c++) 
      {
        arrayclose[c] = iClose(NULL,0,c);
        
       }

Using ArrayFree sets the array size to zero, so of course you get the "array out of range" error.

Ok but how do I fix it?

 

Any help on the other questions?

   double arrayBBLOW[5];
   static datetime bar_time=0;

   if(Time[current]!=bar_time)
     {
      bar_time=Time[current];
      for(int x=0;x<5;x++)
        {
         arrayBBLOW[x]=iBands(NULL,0,20,2.5,0,PRICE_CLOSE,2,current+1+x);
        }
      if(Close[current+1]<arrayBBLOW[0] && Close[current+2]<arrayBBLOW[1])
        {
         //Do stuff
        }
     }
This may give you some pointers
