I think we DO agree on the facts: when RTQ
window is minimized, only the data
for open charts is being updated.
Actually, with “Automatic backfill
on first data access” disabled (in database settings),
even with RTQ window open the same
applies: only the data for open charts is being updated.
The reason why in my case this is unsatisfactory
is that for each symbol I view,
I use 3 timeframes. Each symbol uses (only) 2 panes (price and one indicator pane).
With this setting, when I view 2 symbols,
even though Broker.exe never
consumes more than 50% of CPU power (window task manager window),
the response time of AB becomes unbearable and hardly usable for intraday
trading.
In busy market times, the delay between clicking
on a tool button and it being recognized
(the button gets selected) takes sometimes 2 seconds, and the time for the
pointer to change
into a hairline another 2 seconds.
When I try drawing a trendline, it takes
forever to line up the end point to where I want it.
Often I have to repeat and move the end point several times.
This hinders my ability to pay attention to
market activity while I am fiddling around with
drawn objects.
So, talking about opening another
instance of AB is out of the question, even though
4 symbols would have been sufficient for my needs.
My computer is fairly powerful, I have 2GB
of RAM, large HDDs and a fancy graphic card.
I do not think my indicators are particularly complex. So, this must be a
typical situation
for my circumstances.
This leads me to the conclusion that the
only workable solution would be to be able
to switch around and open new symbols in real time.
If any AB user there doing daytrading has
a different experience I would appreciate hearing about it.

Testing today with RT feed on: With RTQ
window minimized (auto hide),
I continue to get RT quotes and my visible charts continue to be updated in RT.
This is NOT true for charts that are not shown. However, I believe you can open
a second main window and view a different chart sheet and they will both be
updated.
This 2nd window can be minimized or simply covered up with the other
main window.

I did
not mean you can not minimize the RTQ window, yes, it is physically possible
to do of course.
But,
when you do that no data is collected for any symbol in that TRQ window!
Only
the data for symbols in open chart(s) is then being saved!
Even
with RTQ window open, I am not sure data is saved under all conditions.
(you can try and check the date stamp on the data files, or you can disable
auto back fill and switch between symbols looking for holes in intraday data).
This
is a not well advertised behavior of AB the reason for which I do not
understand.

I
just tried it and was able to minimize it. At first all I saw was the small x,
but after moving it left and back again, the pushpin showed up and now it's an
auto-hiding tab at the bottom. I assume it will still update, but can't tell
now.

This
is really a pet peeve of mine.
I
would say stocks updated means the data for all the TRQ listed symbols
is being saved to the local database in real time or a timely manner.
The
purpose is to be able to switch from one symbol to another
with no delay and a full set of data points. There are only that many
symbols you can keep open charts open for before exceeding any
CPU capabilities.
Also,
when using tick based data the backfill poses some limitations in its
functionality
(maybe because of IB’s restrictions).
In
short, unless the data saving of a limited number of symbols is a serious
burden on AB I really do not understand the reason for this restriction.
On a
positive note, there is one good reason to keep TRQ window open (slightly),
it is monitoring that data is coming in (background of the price changes to
yellow
and moves around). I keep my RTQ window a small size vertically oriented just
to see
the Last Price of a few symbols. I have had more than one occasion that even
though
the status “light” was green, no data was registering. Only
“Reconnect” fixed it.
An
ideal user friendly feature could be an built in data arrival check with
optional alarm,
and a pull down list of a user definable subset of TRQ symbols used to switch
between symbols with no requirement to have TRQ open at all.
(the existing pull down of symbol selection list is just too long to allow quick
switching)

Hello,

What do you mean with 'stocks updated'.
If you want to have CHARTS updated - they are
updated
automatically (all open charts).
If you want SCAN/ EXPLORATION / BACKTEST - you
don't need
to run RTQ window. Just use "wait for
backfill"
>
> When I hit the X, does it still update all
the stocks?
If it was open and you close it then yes,
but what for you need to constantly update? Data
is delivered on demand. If something is missing - BACKFILL
feature is to fill the gap. (Unless you run feed
that has no backfill).
BTW: did you notice "auto-hide" feature
in beta? It is just "minimized window".
