Status( "firstbarvisible" ) can be used when you want plot some value
relative to what is shown on the screen. Not any use in an exploration
eg
bar = Status( "firstbarvisible" );
firstbar = bar and ref(bar,-1)==0;
lastbar = bar and ref(bar,1)==0;
as for funny behaviour of some indicator plots, Ab has something
called QuickAFL which allows for calculating and plotting only the
minimum required to show on the screen, mostly for the built in
indicators. To override this you add
SetBarsRequired(10000,10000);
to your plot AFL. This allows for calculating as many bars as you have
included in the brackets, although can slow down the plotting a bit.
Hope I understood your query.
