  so what is the problem? you can have a two-dimensional array, second dimension must be fixed, first can be dynamic and change. e.g. int array[][3]; then add more elements by using ArrayResize function - it is well documented so please show what you did and why it does not work so that we will try to help you wiht your code.

What I believe you are looking for is an array of structs. A struct is an object that can hold different types of data. Here is a example you can run in your terminal.

void OnStart()

 struct MyData string name; double price; int volume; ;
 // initializing an array of structs
 MyData arr[] = 
 "USDJPY", 110.000, 200,
 "USDJPY", 110.100, 300,
 "USDJPY", 110.200, 400,
 ;
 // changing some values 
 arr[1].name = "EURUSD";
 arr[1].price = 1.12;
 arr[1].volume = 1000;

 for (int i=0; i<ArraySize(arr); i++)
 printf(
 "Symbol=%s, price=%.3f, vol=%d", 
 arr[i].name, 
 arr[i].price, 
 arr[i].volume
 );

  When initializing any array, regardless of type, you can only use constants not variables. Why do you tell me what you're trying to do and maybe I can show you a better way.
