Hi all


I would like to sort 8 global variables that are constantly updated.

I have read ArraySort() fuction... but I can't figure it out.

 //////////////// GLOBAL VAR ////////////////////////
 int GV_TOTAL_ASSET_AUD = GlobalVariableGet("GV_TOTAL_ASSET_AUD");
 int GV_TOTAL_ASSET_CAD = GlobalVariableGet("GV_TOTAL_ASSET_CAD");
 int GV_TOTAL_ASSET_CHF = GlobalVariableGet("GV_TOTAL_ASSET_CHF");
 int GV_TOTAL_ASSET_EUR = GlobalVariableGet("GV_TOTAL_ASSET_EUR"); 
 int GV_TOTAL_ASSET_GBP = GlobalVariableGet("GV_TOTAL_ASSET_GBP");
 int GV_TOTAL_ASSET_NZD = GlobalVariableGet("GV_TOTAL_ASSET_NZD");
 int GV_TOTAL_ASSET_USD = GlobalVariableGet("GV_TOTAL_ASSET_USD");
 int GV_TOTAL_ASSET_JPY = GlobalVariableGet("GV_TOTAL_ASSET_JPY");
 

 
/// From ArraySort documentation:

   double num_array[5]={4,1,6,3,9};
  // now array contains values 4,1,6,3,9
  ArraySort(num_array);
  // now array is sorted 1,3,4,6,9
  ArraySort(num_array,WHOLE_ARRAY,0,MODE_DESCEND);
  // now array is sorted 9,6,4,3,1



// I have tried this: but I got an error as it requires constant ?

   double num_array[8]={GV_TOTAL_ASSET_AUD,1,6,3,9};


Please help

Cheers

Finally I don't get what I was expecting:

 //////////////// GLOBAL VAR ////////////////////////
 int GV_TOTAL_ASSET_AUD = GlobalVariableGet("GV_TOTAL_ASSET_AUD");
 int GV_TOTAL_ASSET_CAD = GlobalVariableGet("GV_TOTAL_ASSET_CAD");
 int GV_TOTAL_ASSET_CHF = GlobalVariableGet("GV_TOTAL_ASSET_CHF");
 int GV_TOTAL_ASSET_EUR = GlobalVariableGet("GV_TOTAL_ASSET_EUR"); 
 int GV_TOTAL_ASSET_GBP = GlobalVariableGet("GV_TOTAL_ASSET_GBP");
 int GV_TOTAL_ASSET_NZD = GlobalVariableGet("GV_TOTAL_ASSET_NZD");
 int GV_TOTAL_ASSET_USD = GlobalVariableGet("GV_TOTAL_ASSET_USD");
 int GV_TOTAL_ASSET_JPY = GlobalVariableGet("GV_TOTAL_ASSET_JPY");

// lets assume that:
int USD_strength = GV_TOTAL_ASSET_USD, GBP_strength = GV_TOTAL_ASSET_GBP, JPY_strength = GV_TOTAL_ASSET_JPY, CHF_strength = GV_TOTAL_ASSET_CHF, EUR_strength = GV_TOTAL_ASSET_EUR, AUD_strength = GV_TOTAL_ASSET_AUD, CAD_strength = GV_TOTAL_ASSET_CAD, NZD_strength = GV_TOTAL_ASSET_NZD;
   
// create and initialize arrays
string currencies[] = {"USD", "GBP", "JPY", "CHF", "EUR", "AUD", "CAD", "NZD"};
string currencies1[] = {"USD"};
int num_array[8][2]; ArrayInitialize(num_array, 0);
   
// put data in num_array and sort
//    * as you can see, num_array[x][1] holds the index for the appropriate currency in currencies[]
num_array[0][0] = USD_strength; num_array[0][1] = 0;
num_array[1][0] = GBP_strength; num_array[1][1] = 1;
num_array[2][0] = JPY_strength; num_array[2][1] = 2;
num_array[3][0] = CHF_strength; num_array[3][1] = 3;
num_array[4][0] = EUR_strength; num_array[4][1] = 4;
num_array[5][0] = AUD_strength; num_array[5][1] = 5;
num_array[6][0] = CAD_strength; num_array[6][1] = 6;
num_array[7][0] = NZD_strength; num_array[7][1] = 7;
   
string text = "Unsorted: ";

/*
for (int j = 0; j < ArrayRange(num_array, 0); j++)
   text = text + currencies[num_array[j][1]] + " = " + num_array[j][0] + ", ";
text = StringSubstr(text, 0, StringLen(text)-2);   //removing last comma
// Print (text);
      
ArraySort(num_array);
text = "Sorted (ascending): ";
for (j = 0; j < ArrayRange(num_array, 0); j++)
   text = text + currencies[num_array[j][1]] + " = " + num_array[j][0] + ", ";
text = StringSubstr(text, 0, StringLen(text)-2);   //removing last comma
//Print (text);
*/
   
ArraySort(num_array, WHOLE_ARRAY, 0, MODE_DESCEND);
text = "Sorted (decending): ";
for (int j = 0; j < ArrayRange(num_array, 0); j++)
   text = text + currencies[num_array[j][1]] + " = " + num_array[j][0] + ", ";
text = StringSubstr(text, 0, StringLen(text)-2);   //removing last comma
 Print (text);


I would like to get this in case

int GV_TOTAL_ASSET_USD = 20; 
int GV_TOTAL_ASSET_AUD = 16; 
int GV_TOTAL_ASSET_EUR = 10; 
int GV_TOTAL_ASSET_NZD = 8; 
int GV_TOTAL_ASSET_CAD = 6; 
int GV_TOTAL_ASSET_CHF = 0;
int GV_TOTAL_ASSET_JPY = -5; 
int GV_TOTAL_ASSET_GBP = -13; 
Rank_USD_strength = 1; // First (strongest)
Rank_AUD_strength = 2;
Rank_EUR_strength = 3;
Rank_NZD_strength = 4;
Rank_CAD_strength = 5;
Rank_CHF_strength = 6;
Rank_JPY_strength = 7;
Rank_GBP_strength = 8; // Last one (weakest)


Please help

Cheers
