Thanks 'longhorns'
With regards to volume, Swift does close to 100 mill a day (average), they claim to have 1100 traders around the globe. If you go on their web site u'll see they have a ton of branches around the world.
I would put it higher than 100 mil actually. All offices combined add more than 40 mil in liquidity to just INET on Nasdaq in one day. Then add ADFN, BRUT, ARCA, any Supermontage, and the other ECNs we have access to plus any orders removing liquidity. Then add all of the guys who trade NYSE and their volume. (Which I'm guessing would be much higher because I believe there are more traders who trade NYSE) I know it's not uncommon for a guy at our branch to trade between 1 and 2 million a day on NYSE.
So, I really have no idea how to estimate what the total might be. Needless to say, it's fairly massive.
