Don't liquidate a winner to keep a loser. Develop and maintain an exit plan. Follow this plan with rigid discipline. Never add to a losing position. A losing position means you are wrong.
Big movements take time to develop.
Nothing new ever occurs in the markets. Don't try to predetermine your profits. The key to wealth in trading is simplicity. Avoid techniques you don't understand. Don't be overly curious about the rationale behind a move.
