Hello everybody tell me how can i change value to positive in afl if it comes in negative? example difference=(close-open);
if close is 100 and open is 90 then difference would be 10 and if open is 100 and close is 90 then difference would be -10 in result i just want difference between open and close so in both cases it should be 10 please tell me how can i do it? thank you
