When the market makes a huge move such as in the fcpo futures today, many longs were caught off balance... the temptation would be to continue to add to the 'gamble' by averaging or 'holding on and hope the market comes back'.... It is good to remember to read this "Don't lose your shirt" (babypips.com)
"The 2% rule will protect you from being eaten by the sharks, while the 6% rule will protect you from the piranha frenzy" Dr Alexander Elder

Most Locals are gamblers. The 66 who remaining are very good (or lucky) gamblers. In fact I think the majority of the 40,000 accounts are losing ones, due to the gambling nature of the markets. As are the 62 inactive Local Participant accounts.
