I am looking to get a data feed for someone for Ninja Trader that provides real-time quotes for the CME (Specifically, ES). However, they do not want to open a live account at a brokerage. I understand that they can get a demo account, but that would constantly require signing up for free trials. What data feeds do you guys have experience with for Ninja Trader that do not require a live trading account? Paying for the data feed is okay, but I would like to keep the cost minimal. Note: Zen-Fire is my data feed of of choice, but as far as I can tell, they only provide there service through brokers that require a live account to keep using it. Also, in case you are wondering, this is for someone that enjoys paper trading as a hobby. And no, it is not me.
