Robinxxx-look at Sierra Chart dot com. I have used it for the last 9 months, $24 USD a month, works with IB and many other feeds. It doesn't have backtesting though, but if you need good basic charts, it is the best value for the $$$.
if you are planning to do autotrade with it, my recommendation is -- think twice. The EasyLanguage is NOT 100% supported. A lot of the key words are not there. You can go to their website and check.
