Which zen-fire brokerage?

[taotree]

I'm going to be doing custom software development against an API and I've pretty much decided that I want to use zen-fire, so...

My next questions is which brokerage to use that will allow me to use the zen-fire API?

Which brokerage to use that offers:

1) <= $2500 minimum to open account

2) <= $1000 ES intraday margin

3) highly competitive commissions (even for low volume)

4) No monthly fees

5) No minimum activity

Any recommendations?

Related... I recently saw some posts about people signing up with Dorman/Mirus or RCG/Mirus--why would one choose to go with Dorman/RCG as opposed to direct with Mirus?

Thanks!

Mirus would be your introducing broker, Dorman or RCG, as an fcm, would maintain your account (and hold your money). Ask mirus for a recommendation on which fcm to use.

Just to finish this thread off, based on various research on message boards and such, planning to go with Mirus.
