thanks brian, Midpoint = (H + L)/2; Plot(Midpoint,"Midpoint",1,1); this is not as scary as i thought. i've read a c++ intro but ALF is obviously much more friendly because it knows constants like H, L and functions like plot.
after my c++ reading i knew programming is not for me. i now think it could be possible, for me, to learn this code. i hope to be back with some lines of code of my own. thanks again and greets, jacco
