I've been using Telequote for about 3-4 months now. The data feed is good, provided you have a decent broadband connection. The data feed, though, needs to be refreshed every hour or so, since due to some problem it gets stuck. That seems to be the only problem so far. I think, it is a PERL based software, just like Spider IRIS, which, therefore, will not look as great as a MetaStock or Advanced GET. When the chart refreshes, the trendlines dance around irritatingly, but settle down as the chart stabilizes. Studies are ample.
Overall, perhaps not worth the money you will be paying, but then what other alternative do you have? Data feed is good, fast, and reliable. It is not delayed as someone has mentioned in his/her comment. I haven't checked Reuters service, so cannot say how Telequote stands in comparison. Last time I spoke to my Viratech rep, he mentioned some other client requesting him to configure the client's MetaStock RT for the Reuters feed the client had purchased. But he was unable to do so. I don't know the full details.
Finally, Telequote works well, and is the only charting software that is used across all the commodities broking houses.
