do you know who is the most active member on the Eurex for dax, bund, eurostoxx?
I mean not a bank, but some proprietary trading firm that trade with own capitals or offer services to other traders too,
in germany I think,
most prop groups clear through a clearing house, rather than self clear.
The biggest clearers for Eurex are either Man Financial (since the Flipper clears GNI and GNI clear thru Man) or Fortis (many arcades & prop groups clear Fortis)
