http://arindatrading.com/Software for traders, by traders
We?re building the next generation of trading platform for active stock and options traders. Active traders need reliable, high-throughput, low-latency applications that are feature-rich (but not bloatware) and intuitive to use, and that display real-time and historical data which is comprehensive and error-free. No application available at the consumer level addresses all of these needs. Yet.
