Re: [amibroker] Time required for functions

[Ara Kaloustian]

Tomasz,

I thought Quick AFL would adjust the number of bars to what is necessary.

I assume I need the same number of bars to compute indicators, regadless of 
time frame.

If my assumption is correct, then why does the number of bars increase?

Thanks

Ara

  There are less 15 min bars than 5 min bars. That's why.

  When using LinRegIntercept make sure to use latest version (5.20) and if only 
possible
  use scalar "period" (i.e. constant) - as it allows to internally enable 
certain optimizations that make function much faster.

    When I switch time frames, the amount of time required per function changes 
drastically. Anyone understand why?

    Execution times from    GetPerformanceCounter( )    function


    Example:

    Function                                  5 min Bars             15 min Bars

    LinRegIntercept                         0.524 ms                  0.176 ms
