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,Tomasz Janeczkoamibroker.com

Subject: RE: [amibroker] passing
variables
<FONT face="Century Schoolbook, New Century Schoolbook"
size=3>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
