Automated, relatively useless.
I have found the best to be Real-Time futures. com with Ben Lichtenstien (sorry bout' the spelling). For some it's just irritating noise but I found it very useful for extremely short-term trading (i.e. scalping).
If your someone who can't take a shit without first looking at four charts each having five different technical indicators on it....... then squawk is going to be pretty much useless to you. But if you like to feel that your at the centre of the action in the pits, and you take the time to learn how to interpret it, it can be a helpful tool.
