$140.00/month/exchange for Rithmic users; $156.00/month/exchange for NinjaTrader Live account holders. This fee is charged to your credit card (or other payment method). The data fee is charged before the end of each month for the following month.
Please note that the CME charges data fees on a per-calendar-month basis and does not prorate charges. Even if the data is turned on during the last week of a month, the full monthly fee ($140 or $156, depending on the platform) will apply, regardless of the number of days the data is used. These are pass-through fees charged directly by the exchange and are subject to change at any time.
