"It is an artificial distinction to think of simulated trading as practice and live trading as real performance. All performance is practice if it occurs in the framework of concrete plans for self-development. The evolving performer asks: What will I work on today? How will I work on it? How will I know if I'm successful? What have I learned today that can be utilized tomorrow? The role of a trading journal is to structure responses to these questions and keep them in conscious awareness."
