Dt, you are going to shoot me...but we are so close that i take that risk!
Making a slight change to your code I added a Param() to modify the close
and I changed the Ref(C,-3) to Ref(Ti3,-3) - no significant changes thus.
Now click on any bar and change the Close to the point where the two Ti3s
(Red and Black) cross, at this point the C (Black)should be equal to the
predicted Ct (Green should meet Black). It does not. Can you explain where i
went wrong?
many thanks again,
herman

Subject: [amibroker] Re: DT's Ct prediction for the Ti3
Scenario III
If the next bar Ti3 should be equal to the Close 3 bars ago, then
calculate the next bar Close Ct.
We shall work again the scenario II formula, since we know Ti3t and
we ask for Ct.
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=Ref(C,-3);//the condition
Plot(Ti3t,"Ti3t...",colorRed,8);
//the 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...",5,8);
PlotShapes(shapeCircle*(abs(Ct-Ref(C,1))<0.02),colorYellow);
In CSCO chart I see a yellow circle on Feb3, 2004.
For this date we read Ct=24.06, Ti3t=25.96.It means : If the next bar
Close is 24.06, then the next bar Ti3 will be equal to 25.96.
The next bar close was indeed 24.08 and the next bar Ti3 was 25.96
I hope it is clear, I have nothing more to add.
