1. Through bottom range analysis

When crude oil prices do not break through the bottom or top of the previous period, crude oil investors must not prematurely conclude that the general trend or the small trend has emerged. change. When the market is bullish, the price of crude oil futures will rebound soon after falling, and the decline will not be very large, forming a double bottom or multiple bottoms above the bottom. But once crude oil prices fall below the original bottom, it means that crude oil prices will fall to even lower points before some important rebound.

2. Through top range analysis

When double tops or multiple tops appear again, but 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, which is better to enter the long position. All fake price changes often appear in the post-bull or bear market stage, and investors should conduct trading operations only after clear bullish or bearish signals appear.

3. Analyze the length of the pullback time

The length of time is an important way to judge whether the general trend has changed. The specific rule is that after the general market has passed for a period of time (that is, it has reached the stage of depression), the time of decline in the depression stage exceeds the previous longer period of decline. At this time, the general trend often begins to change.
