I generally second Richard's cautions; the TS4 Signal server is band-width
limited. My portfolio has been whittled down to 30 symbols in order to keep
up with the tick flow. I am, however, running the dynastore/quote.com setup
on one computer (a PII 450 with 128 MB of RAM) and it has never crashed as a
result of these programs. I also use the same computer for concurrent online
trading, email and general surfing. I use Rambooster and think that it has
helped prevent crashes from low RAM reserves.
Incidentally, all Signal symbols are available at the DBC web site. One
quirk - quote.com has two different futures symbol nomenclatures, which
allows you to create artificial contracts. I created a emini
day-session-only contract that I use for certain indicators.

Generally, yes. The symbols for BMI and Signal are tenerally not the
same, except for stocks. For indeces, Signal adds a $ to the BMI symbol
(example, INDU in BMI, $INDU in Signal). For futures, Signal adds a
space (SP0Z in BMI, SP 0Z in Signal).

I have used TS4 with DynaStore both in the same computer as DynaStore
and in a separate, dedicated computer, and I recommend the latter. In
my experience, I have fewer crashes with TS4 in its own box.
In the attempt to lessen the number of crashes still, I have purchased a
high-speed, data buffered, serial port card, and now plug the null-modem
cable into it instead of into a ComPort in the second computer. So far
(albeit only one day), I have yet to get a crash using the serial card.
The card I use is a TurboExpress Port 920 card from Pacific CommWare,
for $80. See http://www.turbocom.com or call 541 482 2744.
I and others have experienced crashes (or the data stopping dead in the
water) from time to time with DynaStore and TS4. Those occur usually at
the open of the market and at other times of high market volatility.
I've attempted to lessen the probability for crashes not only by using
the serial card but also by gathering data for only few issues (3
indeces, 3 futures, 2 stocks). That seems to work for me. I would
caution, however, planning on using DynaStore and TS4 if you plan on
loading up on lots of issues, particularly if they have high tick rates,
such as INDU and the more volatille stocks, such as MSFT, have.
I attempted to get around the problem with TS4 and DynaStore by using
Ensign for eSignal. Yes, it works and is inexpensive --- only $30
monthly. It has to be used in the same computer as DynaStore, however,
and it also has nowhere near as easy a programming language as does TS4
(EasyLanguage). For those reasons, I did not pursue it further.
I wish you well in your new adventure.
Sincerely,
Richard
