It sets it to the maximum of the number of bars back you could reference either in a look-back loop or plotting back in time even if your code would never do that.
For example,
if LastBarOnChart then begin
Plot[100](Close, "C");
end;
will require a MaxBarsBack setting of 100 even though might have 1000 bars of data on the chart.
Very painful! I wish they would dynamically determine the MaxBarsBack requirement and simply give a run-time error message if you violate it...
