Re: [amibroker] Does Amibroker always loop through the array?

[Graham <kavemanperth@xxxxxxxxx>]

You only use the array identifiers when you are going to do a loop. It
is best to either use ref( X, -P) or valuewhen( barindex()==P, X )
With charts and the quickafl the value of barcount can vary as Ab will
only use the abrs necessary for the plot on screen. so you may
sometimes get incorrect values for barcount
