The operator "or"

New comment
 

While using "or" for say 5 statements, if the first or second return true will MQL4 still check all 5?

Thank you. 

 

No.

From MetaTrader 4 Trading Terminal build 600 with Updated MQL4 Language and Market of Applications Released:

  • Shortened conditions check is now used in logical operations, unlike the old MQL4 version where all expressions have been calculated and the check has been performed afterwards. Suppose there is a check of two conditions with the use of logical AND
      if(condition1 && condition2)
    {
     // some block of operations
    }
    If condition1 expression is false, calculation of condition2 expression is not performed, as false && true result is still equal to false.
