Re: [amibroker] profiler checks and finds cci function most offending

[Dennis Brown <see3d@xxxxxxxxxxx>]

Yes, CCI is a calculation time hog.  It is the nature of the CCI  
algorithm.  I use CCI sparingly and never recalculate them if I can  
save the result from a previous calculation.  The real time penalty  
comes when referencing a large range, as CCI calculates the whole  
range for each bar.  Look up the actual CCI algorithm and you will  
understand.  Depending on the details of what you are doing, it might  
be possible to save out the CCI as an ATC instead of recalculating it  
over and over if for instance you were using it with an optimize for  
other parameters that do not affect it.
