First, through bottom interval analysis

When the price of crude oil has not broken 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 before some important rebound occurs.

Second, through the top interval analysis

When there are double tops or multiple tops again, but the price has not risen 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 there are obvious bullish or bearish signals.
