The Ten Commandments of Trading
by Lewis Borsellino, "The Day Trader's Course", pg 13-16:
Commandment 1. Trade for success, not for money.
Your motivation is the well-executed trade.
Commandment 2. Be disciplined.
The disciplined trader - regardless of profit or loss - comes back to trade another day.
Commandment 3. Know yourself.
Commandment 4. Lose your ego.
The quickest way to end your career as a trader is to let your ego influence your decision making.
Commandment 5. Understand that there's no such thing as hoping, wishing, or praying when it comes to the market.
Commandment 6. Let your profits run and cut your losses quickly.
Commandment 7. Know when to trade and when to wait.
It is not practical or possible to trade every day, all day... If the market doesn't have a clear direction, then wait on the sidelines until it does. Meanwhile, keep your mind on the market, but keep your money out of it.
Commandment 8. Love your loser like you love your winner.
Maybe even more. Losing trades will be your best teachers.
Commandment 9. After three losing trades in a row, take a break.
Commandment 10. Observe the unbreakable rule.
As we all know, you can break a rule and get away with it once in a while. But one of these days, the rules will break you.
