Hi Chuck,
I wrote it in C++. I also have some experience with 
Delphi
but not in writing DLLs with Delphi. I've also the 
Linux version 
of it (Kylix) on my desk for some 
time now, but still had no time
to install and play with it.. 
:-(
UM

  That

  send a beta, that would be great!

  Did 
  you write the dll in Delphi or C++?   Has anyone written any 
  plug-ins in Delphi?

    Hi Chuck,
    would the following help? If yes, I can send you 
    a 
    beta of the plugin. 
    But, it is a beta and not 
certified
    yet by amibroker.com. 
    
    I'm open for more useful additions to the 
    plugin.
