Thanks Steelhead.
From reading the Mirus reviews here at ET, it appears that Mirus is considered a solid broker for trading futures using NT/ZF. They also have lower commissions (4.40/rt for the ES) and lower margins than Dorman. For me, lower margins means I don't have to have so much cash in the futures account earning a low interest rate. I like the idea of going through Dorman directly, but going with Mirus and clearing with Dorman seems to have advantages. Having said that, I do have a few questions:
1. Why would someone go with Dorman directly as opposed to Mirus and clearing with Dorman?
2. How could Mirus, a Dorman IB, provide more competitive commission rates than Dorman?
3. Do most people go with Mirus as opposed to Dorman? It seems to me that most go with Mirus just based on the number of Mirus posts vs Dorman posts - just an observation.
4. For those that trade with Mirus and clear with Dorman, why did you not go directly with Dorman and eliminate the middleman? I know Mirus is a business partner of Dorman so "middleman" may not be the correct term.
5. Who has a better staffed trade desk, Mirus or Dorman?
Thanks.
