comment What tools exist for order book analysis and visualization?
Nice link, thanks for sharing and welcome to quant.SE! I agree, building your own is not that hard, but I'm always interested to see what exists out there to get ideas. This is the best visualization I've seen, and the features for moving through the day are very nice.

comment How fast is QuickFix ?
Thanks for the additional data! Can you edit you answer and include it there? That way it won't be missed if folks aren't reading comments. I'm out of votes right now, but will up vote you in a few hours.

comment How fast is QuickFix ?
Welcome to quant.SE! Can you elaborate a bit on your usage of QuickFixJ? How many orders per day? Do you measure order to accept latency? Some informative stats about your usage would be very interesting.

comment Do you have historical tick data you want to donate?
They pay handsomely for the data and the right to let people download/view it. Also, daily data is not considered that valuable. It's the intraday stuff that the exchanges consider to be worth its weight in gold. Where intraday data is available, like on Yahoo, no history is made available. Yahoo licenses their intraday data from BATS, so even though you're getting the "real-time" quote, its only what's displayed on BATS Z.
