Great...but
I am programmatically challenged. Is the param1 statement in the
included file, it looks like it would have to be there. Could you
provide a more elaborate example please?
Cheers
Sid

Sid,
There
is absolutely NO problem with
that.
You
can use optimize and pass arguments to ANY function defined in external
file.
#include
<file_with_your_function.afl>
param1
= Optimize("param1", 5, 1, 10, 1
);
buy
= C > MyFunction( param1
);
Best regards,

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

Hi Sid:
I added this to my function file:
function StoRSI(RSIPer,EMAPer)
{
Low1=LLV(C,7);
High1=HHV(C,7);
return (EMA(100*(C - Low1)/(High1 - Low1),EMAPer)/2) + (RSI(RSIPer)/2);
}
Note the naming and the variable positions in the declaration of the StoRSI function.
I plotted this in my IB window:
X=StoRSI(14,13);
Plot(50,"",7,1);
Plot(X,"StoRSI",5,1);
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.
Hope this helps.
Ken

Subject: [amibroker] passing variables
I use StochRSI fairly often and rather than re-write it all the time I
decided to make a dedicated AFL file that I can include in the other files
where I want to use the function. Of course to be of any use, the
variables need to be passed from the calling program to the included
program. I know how to do that in TS, but I don't see how to do it in AFL.
For my StochRSI fn I would want to pass the Array (usually Close), the RSI
period and the smoothing MA to the include file. Three variables in all.
How is this done?
TIA
Sid
