In C / C++, you can make an "array view" using a pointer like this : int array[100]; int * ptr = &array[50]; // note that array + 50 would work too printf("%d", ptr[3]); How could you achieve the same in mql5 without copying the full array ? (This is to pass to functions like SocketSend() )

I don't think we can create pointer in mql5. However, For Array View you can do something like this. int myArray[5] = {1, 2, 3, 4, 5}; ArrayPrint(myArray, 0, ",", 0, 2); // 0: starting index and 2: element count //Prints 1,2

You pass the array by reference, the function SocketSend is prepared for it. If you only want to pass a part of the array, then you must make a copy. A example of passing by reference: void OnStart(){ int arr[5]= {1, 2, 3, 4, 5}; PrintArrayExample(arr); } void PrintArrayExample(int& a[]){ for(int i=0; i < ::ArraySize(a); i++) Print(a[i]); }
