whats most important is right here..your fcm is known to have retail traders. and the computers tell from the ilink message code that its your order from that retail fcm..
My understanding is not a ratio. I spoke to member services at the CME 2 years ago for an automated client. No manual trader can hit 20,000 message units per day. Even an automated client that needs to enter that many orders just needs to register as a MM. It is about 15 orders per second. What they want to avoid is spoofing and those that do not add to depth and liquidity from using bandwidth. Anyone concerned with this should contact the CME.
when u say cant hit 20,000 messages in a day? i hit 600 in 10 minutes a few nights ago and the trade desk called me to see what i was doing. i could manually put in 20k cancels a day..i was placing lots of orders in the book
also the rules change almost monthly so 2 years ago that you contacted the cme is an eternity. they will give you more clarification but of course it is not without lots of emails amd calls to get the info.
