iHighest function for Indicator data

New comment
 

I am am looking for a function that will be able to return to me the highest/lowest value of indicator values, 

iHighest returns shift of the highest bar 
I want a function like that but doesnt use bars but indicator value;

//---
int Indicator_Lowest(int count=end,int Start=begin) //to return the shift of the lowest indicator price
    {
    int shift=EMPTY_VALUE,tempshift=EMPTY_VALUE;
    double value=EMPTY_VALUE,tempvalue=EMPTY_VALUE;
    for(int i=Start; i==Start+count;i++ )
        {
             tempvalue =indicator(i);
            
            if(value<tempvalue ||tempvalue==EMPTY_VALUE)
                {
                 value=tempvalue ;
                 shift=i;
                }
              //if(shift==Start+count)
                //Start+=count-1;

        }
    return shift;
    }




i tried this not sure if it works

 

Pseudo-code

        // The engine
        highest = -1;            // set to small value
        lowest = 10000000;       // set to large value
        for(int i=index; i< lookback+index; i++)
        {
            highest = MathMax(highest, indicatorValue(i));
            lowest = MathMin(lowest, indicatorValue(i));
        }

Or put the values in an array and use Array Functions

Pseudo-code

I hope to get the Shift of the bar at that current level, 
like the iHighest or iLowest functions return the Shift I am looking for the IndicatoriHighest 

William Roeder:

Or put the values in an array and use Array Functions

I thought of using ArrayMaximum/Minimum then that returns the Arrays max or minvalues where as I need the Shift. 
with that in mind 

double myarray[];
//code funcions 
//then now he function to retrieve the array 


//inside the IndicatoriHighest function
myMax=ArrayMaximum(myarray);
for(int i=0;i<=ArraySize(myarray);i++)
        {
          if(myMax==myarray[i])
            { 
              shift=i; break;
            }
        }
  return shift;
//doesnt feel right to me

will this work or the first one I posted wayabove

 

Jeff,

ArrayMaximum doesn't return the max value in the array but instead the index to the max value location. You don't need to do the "manual" search loop for the location. 

The max value can also be obtained by myarray[ ArrayMaximum(myarray) ]

I hope this answers your question :)

You. Just solved it 
 
ok so it has gone well I think ...

this is what i wanted o do but not working lol
