I notice a very low limit for what they call the volume ratio on ES. 4-1 Firms supposedly being fined if their message/fill ratio exceeds that. Seems very low to me and has anyone has a problem with this? I would think cancel and replace would easily go over 4-1. Other contracts have a limit as high as 75-1. +++++++++++++++++++++++++++= I notice this has been discussed in the past. Still, any recent updates on how this is playing out in real time?
