Looking to dump IB and Schwab. Looking for someone with cheap commissions, too. Good overnight margin is what I seek
not all FCMs are "happy to accommodate" sellers of premium, even if spreads. We offer exchange minimum margins. Friendly, free software and personal help if /when you need it. www.E-Futures.com
The best way to see specific margins for the credit spreads will be to download the platform in demo mode and use the built in margin calculator. ( quick video here: ) or simply look at the CME SPAN margins.
feel free to share the exact strike prices, months, details and I can plug it in as an example - if you like.
