Folks,

Would really appreciate help on this error I am getting when compiling the code but cannot see any reason. I am not a developer.

int Al_1 ;

Al_1 =
(Period() == PERIOD_M1) +
(Period() == PERIOD_M5) * 2 + 3 *
(Period() == PERIOD_M15) +
(Period() == PERIOD_M30) << 2 + 5 *
(Period() == PERIOD_H1) + 6 *
(Period() == PERIOD_H4) + 7 *
(Period() == PERIOD_D1) +
(Period() == PERIOD_W1) << 3;


'<<' bitwise operator are to be applied to integer values only.

thanks

I think it's because (Period() == PERIOD_M30) returns a boolean data type, not integer. Bitwise op apparently requires an integer.

Try something like:
Inserted Code
int Al_1, t1, t2;

if (Period() == PERIOD_M30)    t1=1;  else  t1=0;
if (Period() == PERIOD_W1)     t2=1;  else  t2=0;

Al_1 = 
(Period() == PERIOD_M1) + 
(Period() == PERIOD_M5) * 2 + 3 * 
(Period() == PERIOD_M15) + 
t1 << 2 + 5 *
(Period() == PERIOD_H1) + 6 * 
(Period() == PERIOD_H4) + 7 * 
(Period() == PERIOD_D1) + 
t2 << 3;

or (assuming that I understand what you're trying to achieve):

Inserted Code
    int Al_1;
    switch (Period())  {
      case  PERIOD_M1  :  Al_1 = 1;  break;
      case  PERIOD_M5  :  Al_1 = 2;  break;
      case  PERIOD_M15 :  Al_1 = 3;  break;
      case  PERIOD_M30 :  Al_1 = 4;  break;
      case  PERIOD_H1  :  Al_1 = 5;  break;
      case  PERIOD_H4  :  Al_1 = 6;  break;
      case  PERIOD_D1  :  Al_1 = 7;  break;
      case  PERIOD_W1  :  Al_1 = 8;  break;
    }

Try something like:
[code]
int Al_1, t1, t2;

if (Period() == PERIOD_M30)...
