I do not know whether something has changed during the last years. I
looked at Livecharts (I think) 4 years ago.
Back then Livecharts was intended by Quote.com a service where you
could run a Java applet to display charts in realtime. If I still
remember correctly, the Java applet did not receive true quote data
from the Quote.com servers but instead a stream of commands to
draw/update the chart displayed by the applet.
The Livecharts service however allowed the user to access an
html-based quote history/time series via a HTTP GET request which
could theoretically be used for backfilling and for quote updates if
the user's client application repeatedly requests this html-based
history page. But this approach (pull model instead of push model)
is of course inferior to a true streaming quote service.
My conclusion 4 years ago: The Livecharts subscription (for $9.95 a
month) is NOT a real streaming quote service.
Of course, in the meantime something could have changed and I could
have overlooked ways how to abuse the Livecharts service as quote
service, but back in 2002 I decided not to spend more time on it. The
Livecharts service appeared not very reliable anyway.
For example, when running the Livecharts Java applet (as intended by
Quote.com), data updates suddenly stopped and the chart displayed by
the applet froze/was no longer updated.
