It appears to be a cross between RediPlus,Lava and the watcher. A very solid product for NYSE and Nasdaz scalpers. Looks like they have bullets built into the system, and NYSE openbook and the new NYSE liquidity rollout.
Apparently, Carlin has spent a tremendous amount of money on the product and have alot of SD's working on new rollouts. I have beta tested the product and have seen it live.
I'm just waiting for the rates to come down before I join Carlin.
