In this type of scenario, inbound transactions have to be filtered and matched against other transactions.

For example, say I put out a buy for ticker BLAH between 23.00 and 27.00....]]> Wed, 05 Apr 2006 01:23:54 -0400 Wed, 05 Apr 2006 01:23:54 -0400 Wed, 05 Apr 2006 01:23:54 -0400 Apr 5, 2006 peter lin 1 mis-characterisation of the core problem of messaging http://www.theserverside.com/discussions/thread.tss?thread_id=39745 I don't know if you've ever worked on financial OMS systems where there are dozens to thousands of clients all sending and recieving bids to buy/sell securities.
