I've been wondering about this also. But Trade-ideas gives me a headache everytime I try to look at it long enough to make heads or tails of it. Too many psychedelic colours and doodahs.
RealTick's Hottrend was really nice when I took it for a spin a few years ago but I'm too cheap to pay $250/month when I execute w/IB and not RealTick. If they offered it unbundled I would go for it.
I'm also looking at NeoTicker but man, is this thing complicated. A lot of bells and whistles but a steep learning curve.
Anyother other good ones out there?
