Quote from FredBloggs:
we all know of harris brumfield - tt /xtrader ceo as well as being a bond trading gorilla.
but i just had a thought concerning all this md trader patent action thats been going down.....
as we know, he wants everyone who uses his md trader ladder concept to pay him 10c (or whatever) per r/t for EVERY licensed platform (user) that uses his technology - i.e. most of the futures traders out there.
the only way he can surely get an understanding of this is to get a line in on the order flow thats being created on these platforms - in other words, see everyones order flow, and thus SEE ALL RESTING ORDERS IN THE MARKET!!
am i either....
1/ some conspiracy nut
2/ ignorant of how the tt platform works
3/ had too much sunshine 
4/ one smart cookie who wont be trading on any platform that sells out to the evil one.
5/ other - see comments below....
Definitely #2...
Allow me to explain because there seems to be a lot of misunderstanding on this thread...
XTrader is client software that TT manufactures.
It talks to various servers, one for each exchange. (cme, cbot , etc...). TT calls these gateways.
Both the server and client software is sold to many different FCMs and other clearing members of the exchanges.
For example, i used to run a very small prop firm. I owned my own servers with direct connections to CME/Eurex/CBOT and LIFFE.
On these servers I ran TT gateway software.
On our trading (client) machines i ran xtrader.
When i place an order in XTrader it is sent to TT software running on my gateway. (a machine i control on my own private network that nobody else can see)
From there it is sent directly (over a t1 line typically) to the matching engine at the exchange - sometimes hopping through and exchange owned computer on the way.
Now the only people that know where my order are:
1) Me and my firm
2) The Exchange
3) My FCM (if i need one)
In my case I cleared my trades through FIMAT (my FCM) so they could see my orders (on most exchanges, sometimes they can only see my fills - they get this info from the exchange, not TT)
TT has no idea (and could care less) what my orders were.
there are probably a dozen FCMs and hundreds (thousands?) of people that have their own direct connections to the exchange.
OK now that is JUST for TT software NOT licensees.
People who license are just licensing the concept and have to report fills *in aggregate numbers* for payment of the licensing fee. But TT doesn't get to peek at every piece of server software they might have running out there in real time.
I hope this makes sense if it doesn't please ask me to clarify because seriously what you're suggesting is really not possible. (For TT)
Now the reason i didn't pick #1 is because realistically whenever a lot of money is at stake people cheat. But in this case it is really not possible for TT to do this, even if they embedded a virus in their software because most people firewall off their gateways so they really couldn't "phone home" even if TT wanted them to.
What *could* happen..(and i'm not suggesting that it is or ever has) is that somebody that was not ethical at a LARGE FCM or worse yet at the Exchange itself could spy on where orders/stops are resting. Hopefully FCMs and exchanges take measures to prevent that from happening and maybe its impossible because I am not familiar with their internal workings.
I think the biggest risk would probably be from an FCM but that is pretty wild speculation on my part.
