I am just learning to code mql4 and it appears as though there are no "and" "or" operators which are common to almost any programming language. In the mql4 documentation it gives the usual bitwise and logical operators but no "and" "or". Does this mean that all expressions comparing various conditions will have to be a complicated combination of nested if else and switch statements. Is there no way to write an expression such as this in mql4 without using nested if or switch statements: if(((a>b) and (e>b)) or (r>s)) {} ?

Thank you for your time

use this && for "and"
|| for "or"

example
if(((a>b) && (e>b)) || (r>s))
{
blah blah blah
}

thanks, ejoi
