Or any other exchange for that matter, it's got to be significant and I see deutsche bourse getting hit today as a result.
BofA Merrill Lynch estimates that about 20 percent of trading on Eurex, the European derivatives market that is jointly owned by Deutsche Boerse and the Swiss exchange, is attributable to prop trading. http://www.bloomberg.com/apps/news?pid=newsarchive&sid=a0vQtGTb8dOY I did ask investor relations at eurex but as yet no reply

if 20 percent is genuine ( prop ) trading then thats just an exchange way of saying 80 % is crossed up algo bullshit. eurex are the biggest short of all shares out there along with the cme and nyse. this volcker rule has changed the game. i dont think people have woken up to this yet.
