Re: [amibroker] Re: optimisation not working correctly?

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

"Parameters" in AA only show what you have defined using Param() functions.


As far as optimization is considered, this is MUST READ part of the manual

http://www.amibroker.com/guide/h_optimization.html

"When you decide which combination of parameters suits your needs the best all you need to do is to replace the default values in 
optimize function calls with the optimal values. At current stage you need to type them by hand in the formula edit window (the 
second parameter of optimize function call)."

Best regards,
Tomasz Janeczko
