Because, to implement it as "additional two arrays"
is * a lot * of work (not only in AB but would need to rewrite all real time plugins, because
that would require changes to database structures).
And only 2 of you want that. I am not sitting here and doing nothing.
I would rather put time and effort into something that can be used by everyone and is
not questionable.
What do you think other people would say who wait for their earlier suggestions to be implemented?
As I wrote before - you can collect bid/ask using GetRTData and store it
to artificial array using AddToComposite and GetRTData, or you can write a plugin on your own,
or pay somebody to write it, there is a free, publicly available API for that.
