Below is Vidya someone posted here a while back.

Length=21;
Smooth=5;
Change = C - Ref( C, -1 );
SU = Sum( C - Ref( C, -1 ) > 0, Length );
SD = Sum( C - Ref( C, -1 ) < 0, Length );
CMO = 100 * ( SU - SD ) / ( SU + SD );
AbsCMO=( abs(CMO) )/100;
SC=2/(Smooth+1);
VIDYA=AMA( C, SC*AbsCMO );
Plot( Close, "Price", 4, 64 );
Plot( VIDYA, "Vidya", 5 );
