A good interpretation of that would be..
{VIDYA}
AbsCMO:=(Abs(CMO(C,9)))/100;
SC:=0.78;
VIDYA:=If(Cum(1)<25,C,(SC*AbsCMO*C)+(1-(SC*AbsCMO))*PREV);
If(Sum(C,25)>0,VIDYA,VIDYA);
Here's a more flexible but less precise version (as per the given definition) of VIDYA. The "SC" variable cannot create a factor of 0.78 when it is based on smoothing periods, as below.
{VIDYA (9,2)}
Length:=Input("Length",1,200,9);
Smooth:=Input("Smoothing",1,200,2);
AbsCMO:=(Abs(CMO(C,Length)))/100;
SC:=2/(Smooth+1);
VIDYA:=If(Cum(1)<=(Smooth+2),C,(SC*AbsCMO*C)+(1-(SC*AbsCMO))*PREV);
If(Sum(C,Smooth+2)>0,VIDYA,VIDYA);
And here's a much faster executing version of VIDYA.
Mov(C,2,VAR);

Subject: [EquisMetaStock Group] Variable Moving Average
On paritech.com I red that this is the formula for the variable moving
average.
VMA = (0.78*(volatility index) * close) + (1-0.078 * volatility index)
*previous VMA
volatility index = absolute value of the 9-period Chande Momentum
Oscillator.
Could someone help to translate this into a formula so it could be used
in to metastock. So one can play with the 0.78value or with the value
of the CMO indicator.
Thanks a lot in advance...iGoR
