Here's a starting list a friend emailed me this morning, I found it spot on so had to share. 1) If the market is uptrending, they constantly complain about how high the market is when the economy is in the dumps 2) If the market is downtrending, they constantly complain about how low the market is and blame the media. 3) They constantly predict as if they knew something special. 4) They laugh during the bear markets, probably cause they didnt make any during the bull and this could be their chance. 5) They laugh during the bull markets, probably cause they didnt make any during the bear and this could be their chance. 6) They call tops against the main trend. 7) They call bottoms against the main trend. 8) They immediately claim low volume if a new high or new low was placed 9) They scalp futures and never let a winner run 10) They pick equities that resemble something they cherish or are a fan of. 11) Their charts got more indicators than a commercial ad for Ninja Trader 12) Their data feeds are free or use simulator based platforms to share their charts 13) They trade earnings or big news announcements before and not after. 14) They cant' wait for the market to re-open 15) Holidays piss them off because the market is closed.
