Hello,
I am sorry, one correction is needed to previously posted
picture.
Note that BarIndex represents actual QUOTES. So first quote
will ALWAYS have index of ZERO.
Now the AFL array can be MOVING over available quotes if
you are shifting visible area using scroll bar.
As you can see in this example, the barindex() function in
current execution will give you numbers starting from 11 upto 23 because
current
visible area covers only part of available quotes.
Best regards,
Tomasz
