Superfragalist,
Have you considered using the free data feed from a broker to check
the real time data? InteractiveBrokers has a free data feed and the
lowest trading costs that I know of. (Certainly other brokers have
free data feeds if you want to check them out). The demo version of
Trader Work Station is available free for testing:
"The Interactive Brokers TWS demo mirrors the actual TWS in both form
and function but utilizes 15 minute delayed quote data instead of
real-time, limits the number of displayed symbols, and does not
execute and clear actual orders. The IB TWS demo is available from
12:30am - 11:59pm, seven days a week."
IB's datafeed can also be used as input to AmiBroker. From the
AmiBroker web site: "direct link to eSignal, Interactive Brokers,
IQFeed, myTrack, FastTrack, QP2, TC2000, any DDE compliant feed"
The main complaints about IB are poor response to customer questions
(no phone, just questions through email).
