Hi Demitris, 

Thanks for your interest. Here is the "works".

/*To Optomize*//*
Dbuy=Optimize("Dbuy",14,0,20,1);
Dsell=Optimize("Dsell",8,0,20,1);
X1=Optimize("X1",13,10,20,1);
s1=StochD(X1);
AVST=MA(s1,100);
Buy = Cross( s1,AVST-DBuy);
Sell = Cross( AVST+Dsell,s1);*/

Regards, 

Hal

Is it possible to give us the parameters and the formula
