CS...sorry to disagree with you....
I created a function...as Chuck stated ..in an empty IB window:
function myFunction(x1,x2,x3,x4)
{
return (x1 + x2 + x3 + x4) / 4;
}
Saved this as myfunction.afl
Then in an empty IB window I put the following:
#include "C:\Program files\Amibroker\Afl\myFunction.afl"
x = myFunction(Open, High, Low, Close);
Plot(X,"",colorRed,styleLine);
It worked.....

(for SR)
Please excuse me for cutting in...
I haven't been able to get Chuck's solution to access a function within the
separate AFL directory either, until I used:
Saved within C:\Program files\Amibroker\Afl\myFunction.afl
return (x1 + x2 + x3 + x4) / 4;
That's it. Just one line. No brackets.
Now, within Indicator Builder, my formula is:
function myFunction( x1, x2, x3, x4 )
{
#include "C:\Program files\Amibroker\Afl\myFunction.afl"
}
A2=myFunction( O, H, L, C );
Plot( A2,"function example", colorRed );
Hit APPLY and it should work (with ver 4.36).
I had to insert the #include instruction since it doesn't appear that AB
function commands will search the hard drive for the saved afl file by
simply stating
x = myFunction(Open, High, Low, Close);
AB will search for the called function within Indicator Builder, but it
doesn't appear to out on the hard drive.
