[amibroker] Re: What's wrong with this formula?

["DIMITRIS TSOKAKIS" <TSOKAKIS@xxxxxxxxx>]

Since the error occurs in Line 1, the T3() should have been defined.
T3() is not a built-in AFL function.
It is a user-defined function.
You should write the whole definition formula before the use of the 
application.
If you want to avoid this, you may  use #include statement.
Here is an example:
I have saved the 

//The Ti3 function
function T3(array,p,s)
{
e1=EMA(array,p);
e2=EMA(e1,p);
e3=EMA(e2,p);
e4=EMA(e3,p);
e5=EMA(e4,p);
e6=EMA(e5,p);
c1=-s*s*s;
c2=3*s*s+3*s*s*s;
c3=-6*s*s-3*s-3*s*s*s;
c4=1+3*s+s*s*s+3*s*s;
Ti3=c1*e6+c2*e5+c3*e4+c4*e3;
return Ti3;
}

in my H/D as C:\Ti3\Ti3Ctfunctions.afl
Now, whenever I need a T3 call, I simply write in IB the

#include "C:\Ti3\Ti3Ctfunctions.afl";
array=C;p=10;s=0.8;
Plot(array,"array",1,8);
Plot(t3(array,p,s)," ",5,1);

You may add more t3 s for various array,p,s values.
I hope it is more clear now.
