Regarding the Charge of 70 dollars? needs looking at imo, I can compare to a few others and Gbx is higher end by U.K. to 3 times on some, I can see this is aimed at bigger transactional clients, perhaps once the exchange is more established a percentage scheme with a cap could be a better approach? Leave it to you guys, you know better than me your client base targets. Just seems high if your aiming at attracting a more modest catchment as well as the institutional guys.
