The guy that I sat next to at my first gig (he visits ET from time to time but I'll keep him anonymous) taught me a really good lesson.
He had a 10:30am "check in" every day. If he was down $2,500 or more then he cut himself off and was done for the day - no matter what. How he cut himself off was the best part. He'd walk over to the liquor store across the street and buy a bottle of booze... stating that it was cheaper to drink away $20-$30 than lose another $2,500 being foolish.
Thank god for his sake he had very few losing days like that
The reason why I don't manually trade is that I don't cut myself off like that. It's a very important thing to know when to walk away...
