Kate just sent a great link to this discussion,
buried within which is a link to the CME statement regarding excess
messaging.
Yes, I'm sure that trailing stops affect this,
especially among scalpers who may be adjusting their stops every tick
or so. I'm also sure that the abundance of good front-end trading
software like NinjaTrader, which make automatic target and trailing
stop adjustments, hasn't helped either.

Very interesting, Andrew, thank you. I checked the CME site
and find nothing on cancellation fees. Checked IB's CME discussion
forum and there is no indication that this is coming from IB and not
CME. Can you share any additional information regarding the source of
this? While I don't doubt what you say, I'm reluctant to post this
information to the IB forum without some firm basis in fact.
I wonder if some IB functions such as Trailing Stop are
sending cancel/replace messages on each tick to a higher high or lower
low.
