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 <FONT
color=#008080>#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.
