The swinghigh/lowbar code also has this same "CurrentBar - BarNumber" in
the output. CurrentBar - BarNumber under certain circumstances gives
bars ago from the current bar. This is most likely to occur when code
looks back to a previous bar and that bar is identified with its bar
number. This is not the case in either of the two code examples cited
here and I do not know why CurrentBar - BarNumber is include.
Usually in code you will see that currentbar and barnumber are
interchangeable, e.g., "if currentbar=1 then...". A current bar number
can be captured with "CurrentBar" or "BarNumber". A past bar can only be
captured with "Barnumber". Say you want the bar number of the third
swinghighbar back from the current bar. Use MRO to locate it then use
BN=barnumber to capture its bar number.
