The ultimate essence of futures trading: The first key point: Look at the trend. If the market is in a pump trend, you can go long. If it is in a downtrend, you can short. The second key point: Control your position. Not controlling your position may result in losing everything overnight. The third key point: Trading skills. Be decisive in buying and selling when the trend emerges, and be decisive in selling and buying when the trend changes. Do not go long in a long-term downtrend, and do not short in a long-term pump trend.
