Hi List:

(I sent this to PCQuote tech support, but they can't help until it happens
live and I call them right away)
Any advise would be greatly appreciated.

Problem is that I have a workspace with several (5-6) charts open of the
same instrument (/nq2ug, with 5 minute charts & 50, 100, 150 tick charts)
with 3-4 different indicators in each chart.

Problem is that some charts' data is lagging behind upto 20 minutes
behind the quote monitor's prices and non-lagging chart.  It starts
after the open and all charts eventually catch up to each other when
volume dies down midday.  Although I've had instances where some charts lag
ALL
DAY and doesn't catch up until after the RTH close.  The level of delay is
not
uniform between the lagging chart(s).

It seems the delay is not related to the complexity of the indicator.  I
am running a pentium 4 on a Windows 2000 Pro.  I iniatially believed it to
be
a  RAM issue, so I upgraded to 1.2 Gig RDRAM & still have the same issue. I
have not tried the obvious solution of reducing the number of indicators
on the charts.  Could a certain type of indicator or analysis technique
cause
the delay? (ie. having a system on the chart?)  I reboot the PC every 2
days.

WORST INSTANCE( happened few days later)
The quote monitor's  trade time AND Tradestation time (lower right hand
corner of workspace)  was almost 45 minutes behind the actual time (on
Windows task bar).  So it seems less likely due to calculation intensive
indicators and perhaps PC related?  I reboot the system, after which
everything was on track -- ie it started to collect data real time, but 45
minutes of data were never collected.

This has never happened before.  Prior to this worst instance , random
charts lagged, but never the quote
monitor data.

Can someone point me to any resource/link that could "fine tune" TS2000i's
performance?

Any guidance would be very appreciated.
