ELA Question - BarNumber

["James Hunter" <jhunter2k@xxxxxxxxxxx>]

I am confused.  I need to use BarNumber to refer precisely to the *first*
few bars of a chart and I use a fixed MaxBarsBack (MBB)..

The ELA manual states that

**   BarNumber gets the value 1 on the first bar after the first MBB bars.
**

This does not seem to be right.  Just by inspection of a chart, it seems
that

**    BarNumber is zero on the very first bar on the chart (never mind MBB)
**

If you have come across this, could you clear this up for me?

Thanks
