1. Look at the empty position. Spot crude oil investment, whether long or short, always pays attention to the highest and lowest points of the day. If the daily high and low points (no matter which one) exceed yesterday's highest or lowest point, it means that the market has changed, that is, it is relatively simple to judge long and short points.

2. Look at the strength, spot crude oil investment continues to rise or fall, and the trend changes greatly; However, rockets or waterfalls before breaking through key points are often limited in strength and low in height.

3. Looking at the amplitude, the investment amplitude of spot crude oil is within yesterday's high and low points, and the market is worry-free. But when it is reduced to an unintentional mark, it is often a prelude to change, so we should pay special attention to it; The high and low points of the day exceeded yesterday's high and low points, and the amplitude increased. It is necessary to pay attention to the breakthrough of important support levels at the resistance level. There is no interval fluctuation, but there is room for operation.

4, look at technology, spot crude oil investment every day to see what type of K line is, and make a comparative analysis with yesterday's K line. Mainly pay attention to the changes of pressure level and support level, leave it alone if it remains unchanged, and adjust the operation ideas if it changes.

5. Looking at the target, spot crude oil investment should pay attention to gold and silver while paying attention to crude oil. Although the two are not synchronized, in general, gold and silver go first and crude oil keeps up.

6, look at the principle, spot crude oil investment is short-term, although there are opportunities in long and short. However, there must be a general trend judgment of the market in mind. For example, Xiaobai now is the adjustment after a long-term decline and has not turned over. Be cautious when holding multiple orders in the short term. On the contrary, in the long-term upward trend, short-term holding of empty orders should be cautious.
