Issue with margins on spreads

Hi, im a spread commodities trading, and im trying to use my system here, but C2 dont recognize the spreads margin that are default by CME. For example for RB C2 ask me 5500$ for each leg, for example RBJ4-RBH4 in total 11000$ of margin, but the reality is that i only need 1500$ in the default margins of CME. Im making something wrong or this is the only way that can run? Because then i cant run my system here and how i can refund my 120$ of payment? thanks

I will respond to you by email.

C2 doesn’t accept margin reductions … you need to explain to your subscribers and use more capital on c2.
