I try this symbol:

#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"

and in the tock() is only last "EUR/CAD". In the print, I don't se other symbol.

My question - how to set all Assets like programers - now I see only one:

void tock()
Asset(ASSET1);
..
Asset(ASSET2);
..
..
Asset(ASSETn);
