Data in Array converted to btw 0 and 1 ( normalisation) !

[[Deleted]]

hi,

I have EURUSD close only data in an array. like Data[]

But the numbers are all EURUSD closes for all the records.

How can I convert or normalise all data in the array to between a minimum of 0 and maxium of 1.

Then I can draw data in Indictor box. And other reasons ???

I know I need Max number in Data[] and Min number in Data[] and then spread data based on a ratio back into array ??

Any ideas ???

data[ i ] = ( data[ i ] - min ) / ( max - min )

Thanks just cracked it at 10.12 pm NZD time

// Normalise data between 0 and 100

void Normalise(double& InData[])

{

double max, min, range;

int count = ArraySize(InData);

int k, m;

double Temp[];

k = ArrayMaximum(InData,512,0);

max = InData[k];

m = ArrayMinimum(InData,512,0);

min = InData[m];

range = max - min;

ArrayResize(Temp, count);

for(int i=0; i<count; i++)

{

Temp = NormalizeDouble((((InData - min) / range)*100),2) ;

}

ArrayCopy(InData, Temp);

}

Hi,

do you want to use that normalisation in pattern recognition system or Neural Network Data feed ?

Nope, I need to normalise data for correlation calculations.

Thx
