Aku_Aku Serious User Joined: Sep 2009 Posts: 1,032 Budapest	Variation 1 Code STRING* asymbol[12]; str_cpy(asymbol[0], "EUR/USD"; str_cpy(asymbol[1], "USD/JPY"; str_cpy(asymbol[2], "AUD/USD"; ... and so on... Variation 2 Code TEXT* asymbol = { strings = ("EUR/USD","USD/JPY","EUR/JPY","AUD/USD","NZD/USD","AUD/NZD","USD/CAD","GBP/USD","EUR/GBP","GBP/JPY","AUD/JPY","EUR/CAD"); } I'm not sure the syntax is totally OK, I wrote it without any editor, help or so. Last edited by Aku_Aku; 05/06/21 16:00. Reason: maybe the syntax will be better

my solution:

Code

#define SYMBOLS "EUR/USD","USD/JPY","EUR/JPY","AUD/USD","NZD/USD","AUD/NZD","USD/CAD","GBP/USD","EUR/GBP","GBP/JPY","AUD/JPY","EUR/CAD"
string aSymbol[12];
...
...
if (is(FIRSTINITRUN)){
   while(asset(loop(SYMBOLS))){
         aSymbol[i]=Asset;
   }
}
