Massindex

High guys..

does anyone know how can i insert MassIndex in a cbot?

I struggles a lot trying but to no avail..

all i need to do is compare the Massindex value for the last two bars..

Typically in an if statement..

if

{

massindex[index - 1] < massindex[index - 2] 

}

else {}

On another note.. do you know how i could convert any value to be always a positive value even if the actual is a negative?
