What prop firms use Redi (plus) ... Know brite does...who else?. Maybe it would be easier to ask who clears goldman?
AS a follow-up inquiry, other than Bright, are there any other props using REDI as their platform? To Don, since you have been using REDI, have you personally traded any of the other financial instruments thru the platform, i.e. futures, fx?

Don, You wouldn't be caught dead trading spot fx or the platform is not good for that type of trading?
