If you are currently with DTN IQ, or are considering them, be aware of their cancellation policy. They have a 15 day cancellation. This is bad enough. But what is a blatant ripoff of traders is that if you don't cancel 15 days before the end of the current month, they will bill you for the ENTIRE NEXT MONTH. It takes, what, maybe 10 seconds to pull a data feed? In addition, check all fees and costs before signing. Depending on the symbols you want to access, they can be very expensive. Just a heads-up.
