BarCount does not necessarily == LastValue(BarIndex())
This is because Amibroker uses "quickAFL" which means it only uses enough
bars to "get the job done". This frequently is not all the bars.

Subject: [amibroker] Re: loop counter
Hi Terry,
thank you very much for your explanation !
However it looks a little bit strange. It works still the same.
When set the entire array to 0 with Cnt = 0; and click Apply, it shows
the same value as with the confirmation code in the graph. However
automatically after about 1 second it changes the value to 199 instead
4517
BTW: i know that it displays the number in the title based on my cursor.
Regards
Klaus
