Any service providers with streaming TA data?

Hi all,

Anyone know a service provider with an API that produces streaming TA data tick by tick or with 200ms delay for things like RSI, ADX, MACD etc based on specified bar size and length - such as (2 bars, 5 minutes) or (5 bars, 2 minutes).

If this kind of service doesn't exist, I guess I'll have to hook up to a streaming data provider and calculate these things myself using TA-Lib or something.

Thanks!
