I have used it exclusively as a charting and T&S platform, for over a year. It's free, and i'm cost conscious because i don't trade full-time for a living. I use the IB TWS as an order execution platform.
Previous post was correct in saying that it is only as good as your data feed.
I do cough up the $25/mo for RJT's data feed -- it has been very reliable for the last 6 months. I get LII with the feed -- for what it's worth.
i am currently trying the money.net feed -- i will cancel before my 30 day free trial ends -- it is not steady.
Scottrade data is free -- i have it as a back-up. I know a trader that uses this feed and it seems to be down quite a bit, and is limited to only a handful of stocks.
Indicies and news are weak.
For some reason i lost the ability to log in to Quote.com for their free delayed futures data. I used to run two sessions, one for the futures and one for the stocks i am tracking.
The Medved crew is extremely support conscious -- emails are answered FAST, and they have a few BB's where users and developers post daily. Jerry and his crew are always upgrading and fixing any bugs so the product keeps getting new and better features.
For the price: It is excellent and meets MY needs. (if you download the free version -- do the right thing and click on a few banners a day!)
I hesitate to recommend it, because i don't know what kind of trading you are going to do off of it.
If i were trading full time and depended on procedes for income -- i'd go with something else; probably e-signal and Ensign. But i would defer this recommendation to any of the Pro's on the board.
