[amibroker] Re: DT's Ct prediction for the Ti3

Until then, let us see how it works.

Scenario I: 
If the next bar CSCO close is 19, calculate the next bar Ti3.

Plot(C,Date()+", C",colorBlack,8);
p=5;s=0.7;f=2/(p+1);R=1-f;
e1=EMA(C,p);
e2=EMA(e1,p);
e3=EMA(e2,p);
e4=EMA(e3,p);
e5=EMA(e4,p);
e6=EMA(e5,p);
C1=-s^3;
C2=3*s^2*(1+s);
C3=-3*s*(s+1)^2;
C4=(1+s)^3;
Ti3=c1*e6+c2*e5+c3*e4+c4*e3;
Plot(Ti3,"Ti3",colorWhite,1);
Ct=19;//the next bar Close condition
Plot(Ct,"Ct",colorBrightGreen,8);
//the next bar Ti3 calculation
Ti3t=(C1*f^6+C2*f^5+C3*f^4+C4*f^3)*Ct+
(1-f)*((c1*f^5+c2*f^4+c3*f^3+c4*f^2)*e1+(c1*f^4+c2*f^3+c3*f^2+c4*f)
*e2+(c1*f^3+c2*f^2+c3*f+c4*1)*e3+(c1*f^2+c2*f+c3*1)*e4+(c1*f+c2*1)
*e5+c1*e6);
Plot(Ti3t,"Ti3t...",colorRed,8);

On Aug17, for example, we read Ti3t=18.26
On the next bar, Aug18, the actual close is C=18.99 and the Ti3 is 
indeed 18.26

Scenario II
If the next CSCO bar Ti3 is 19, then calculate the next bar close.

Plot(C,Date()+", C",colorBlack,8);
p=5;s=0.7;f=2/(p+1);R=1-f;
e1=EMA(C,p);
e2=EMA(e1,p);
e3=EMA(e2,p);
e4=EMA(e3,p);
e5=EMA(e4,p);
e6=EMA(e5,p);
C1=-s^3;
C2=3*s^2*(1+s);
C3=-3*s*(s+1)^2;
C4=(1+s)^3;
Ti3=c1*e6+c2*e5+c3*e4+c4*e3;
Plot(Ti3,"Ti3",colorWhite,1);
Ti3t=19;//the next bar Ti3 condition
Plot(Ti3t,"Ti3t...",colorRed,8);
//the next bar Ct calculation
Ct=(Ti3t-R*(c1*(f^5*e1+f^4*e2+f^3*e3+f^2*e4+f*e5+e6)+c2*
(f^4*e1+f^3*e2+f^2*e3+f*e4+e5)+c3*(f^3*e1+f^2*e2+f*e3+e4)+c4*
(f^2*e1+f*e2+e3)))/(C1*f^6+C2*f^5+C3*f^4+C4*f^3) ;
Plot(Ct,"Ct...",colorbrightgreen,8);

On Oct07 we see that we need a next bar Ct=18.75, in order to have a 
next bar Ti3t=19.
On the next bar, Oct8, C=18.78 and Ti3=19.00
