Array with the size of extern variable

New comment
 

Hi I would like to create an array with size of an extern variable. The below is code which generates error. Thanks for your time.

extern int bars=200;

double my_array[bars];
 
Perhaps you should read the manual.
          Array Functions / ArrayResize - Reference on algorithmic/automated trading language for MetaTrader 5
 

I am writing the code in MT4 and this function is the same as MT5, I use the function in the manual and it is still giving me error!

extern int bars=200;

double my_array[];

 ArrayResize(my_array,1,bars );


The error is undeclared identifier bars, however it is already defined as int external variable.

  2. Post all relevant code; there is no context. You can't have ArrayResize outside of a function.
  3. Do you understand that your code only makes the array a size of one?
