To achieve stable profits in trading, initially, you are learning everything, listening to everything, feeling like you understand everything. Sometimes you make a lot of money and think you're on top of the world; other times you lose everything and start questioning life, feeling like a tangled mess! Then you begin to filter out trading systems that match your personality, position size, and habits, and start testing repeatedly. Every loss or gain is followed by a review process. Eventually, you emerge and enter a stage of stable and continuous profitability. Many people, in the very beginning when everything is a tangled mess, have already lost all their capital, so there is no second stage.
