passing variables
Sid,
No, param1 statement in only in the main file. Include file
contains ONLY your function that takes an argument:
// BEGIN.. contents of the file_with_your_function.afl
...
function MyFunction( periods )
{
return AMA( C, 2/(periods+1));
}
/// END
-------------------
---------------------
Contents of the main file:
// BEGIN
#include <file_with_your_function.afl><FONT
face="Century Schoolbook, New Century Schoolbook"
size=3> <FONT
face="Century Schoolbook, New Century Schoolbook" size=2>param1 =
Optimize("param1", 5, 1, 10, 1 );<FONT
face="Century Schoolbook, New Century Schoolbook"
size=3> <FONT
face="Century Schoolbook, New Century Schoolbook" size=2>buy = C >
MyFunction( param1 );
// END
At run time param1 from MAIN file is passed BY VALUE to
'periods' argument in the function.
That way your function is written ONCE and can be used like
ANY OTHER built-in function in AFL
(like MA, ADX, etc )

Subject: RE: [amibroker] passing variables
Clarification:
What I am talking about is the ability to run optimize on the code
that is in the include file. This means the variables are defined
in the main program and the current value is passed to the include
program for the range of the optimization.
Upon further reading of the help files I am beginning to think this
is NOT possible in AB. Someone correct me if I am wrong on
this.
Ken, thanks for your routine, BTW, I think what you posted is
STOCH + RSI rather than StochRSI which is the stochastic of RSI.
Cheers and Merry Christmas to all
Sid

The C/O/H/L/V arrays are
always available, so I only "passed" two variables, the EMA period and
the RSI Period. It gets "passed" when you write the function
within your regular AFL code. In my case, following what a lot
of others do, I #include a regular (and growing) MyFunctions.AFL
file.<FONT

Hope this
helps.<FONT

I use StochRSI fairly
often and rather than re-write it all the time I <FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
decided to make a
dedicated AFL file that I can include in the other files
<FONT face="Century Schoolbook, New Century Schoolbook"
size=3>
where I want to use the
function. Of course to be of any use, the <FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
variables need to be
passed from the calling program to the included <FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
program. I know how
to do that in TS, but I don't see how to do it in AFL.<FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
For my StochRSI fn I
would want to pass the Array (usually Close), the RSI <FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
period and the smoothing
MA to the include file. Three variables in all.<FONT
face="Century Schoolbook, New Century Schoolbook" size=3>
How is this
done?<FONT
