Method 1: First, through the bottom interval analysis, when the crude oil price does not break through the bottom or top of the previous period, crude oil investors must not draw the conclusion that the general trend or the small trend has changed prematurely. When the market is bullish, the price of crude oil futures will rebound quickly, and the decline will not be great, forming a double bottom or multiple bottoms above the bottom. But once the price of crude oil falls below the original bottom, it means that the price of crude oil will fall to a lower point, and there will be some rebound in reopening. Second, through the analysis of the top interval, double tops or multiple tops appear again, but when the price does not rise above the original top, even a bull market should not enter prematurely. Once the price rises above the original top, before it falls back, the price will often show obvious signs of rising, and it will be better if it enters the long state. Sweet dreams, sweet dreams. All virtual and real price changes often appear in the last stage of a bull market or a bear market. Investors should trade after obvious bullish or bearish signals appear.

Method 2: The most intuitive and effective way to make a bill for spot asphalt is to draw a trend line. K-line directly reflects the process of the struggle between long and short sides. Looking at the green line, we can intuitively see which trend the market is in. If the red line goes straight up, it depends on the trend. Then look directly at the nearest high point and place where the K line connects, and you can draw the trend line channel, or the red line and the green line go down directly. You can see the relationship between the current price and the trend line.
