We know the probabilities of the chart pattern being successful, and the reward to risk is on the trader's side. It then becomes a process of continuing to trade when the probabilities and patterns are presented to the trader. A good analogy can be made in professional sports. Whenever Michael Jordan and the Chicago Bulls played they were heavy favorites. In the stock and commodity market the probabilities of success are in your favor and the reward is highly favored on your side.
Risk control is what trading is all about.
Once a belief structure is in place the next step is trade execution. The foundation of this belief structure must be in place before trading commences. If it is not disaster will follow. Trader's must believe in what they do. Discipline comes from knowledge and experience in recognizing the probabilities in trading.
