Thx Tomasz,
Although I don't receive it, I get the picture. However, using
LastValue should mean that WITHIN the same chart-view (i.e. visible
area), choosing another bar via the Selector Line should not change
the Maxbar result?
It's shocking I don't get this after so many years. And I'm now
wondering there is probably no way to get the number of ALL bars (the
full history) unless you use all quotes in AA/the chart, or is there?
