Because this has been such a good market for trading index futures contracts, I'm sizing up and becoming a bit more aggressive. But even with tight stops and no overnights, I'm becoming concerned about exposure to a 9/11 type event, should it occur when I am in long positions. Does anyone on this board have knowledge of any moves that were made after 9/11 to enhance protections/backups to mechanisms at the major market centers, such as NYSE, CME, etc.
