Howdy, just wondering if there are any instances when an order queue could be rendered visible. All this adding and pulling bids before they are lifted really implies someone (mm:s?) know their place in the queue and can time cancellations in a very precise manner. Is this possible, is there a difference between different order matching systems in this respect? Or is it a total lock on the order queues because them being visible would screw things up? Would appreciate any input. Thanks
