they know exactly where your stops are they always have and they always will. ust because teh cme and your broker tell you. there is no way they know where your stops are doesn't mean they don't because they do! the may not know your price but they know when orders get sent to the CME because DIRectr access get bandwidth numbers and they can sift thru each and every order because it is electronic and they know when stops are being placed. not necessarily the exact price but they know there are orders. this is rearly discussed because people seem to want to believe that trading is so difficult because it is fair. not sure why everyone understands vegas is not fair but they still play.. this mkt is the same exact way. it is rigged and you gotta play the rigs and understand when real rigging is going on just to get you out. most undercapitalized day traders like everyone on this site.. place stops less than 200 or 300 dollars for a day trade right? add up all your stops.. so when they gun for stops they only need to move 10 to 15 points past all the "bandwidth interference" don't foget they took the OPPOSITE side of your trade. they knew you were filled before you were.. so as soon as you are filled they can account for the bandwidth interference because they are on the opposite side of 70 % of all trades. so they know what interference to look cut out and what interfernce was a sell stop to get out or a profit taking limit. they also know who they are doing business with. because they know your FCM in the order. that part is legal because they are the counterparty and have default risk should your fcm go bankrupt in the next 5 mintues and they just matched 10,000 eminis.
