I am an Interactive Brokers customer where the Globex Level II data for ES is included at no extra charge. I am thinking of moving to NinjaTrader Brokerage. With NT, apparently, there is an ongoing extra charge for data (in addition to the commissions and exchange fees). Do I have this right? And it looks like there are at least three choices: Kinetick, Continuum & Rithmic. What are the differences between these three; i.e., what type of trader would typically choose which and what are the price differences? These data differences and fees are not clear on their site.
