there are too many to list. tons of order entry mistakes that add up. a few long term plays that come to mind are being long 15000 shares of SIRI at 3.75 and sold at 4.10, and long 6000 shares of XMSR at 6.15 and sold at 5.75 - both were intended to be long plays. my gf wanted to buy GOOG when it came public, but i didn't.
had a chance for a second interview at Timber Hill to work in the SP Futures Pit, but i made a mistake on the trader's name when i went to call him. contacted original interviewer and he said, we have no one by that name, thx for your interest. oh well. not sure it's that bad as i'm doing pretty well, but it was still stupid to write down the guy's name wrong.
