When the price of natural gas has not broken through the bottom or top of the previous period, crude oil investors must not prematurely draw the conclusion that the general trend or the small trend has changed. When the market is bullish, natural gas futures prices will rebound soon, and the decline will not be great, forming a double bottom or multiple bottoms above the bottom. However, once the price of natural gas falls below the original bottom, it means that the price of natural gas will fall to a lower point before some important rebound will occur.

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.

Third, analyze the length of the decline time.

The length of time is an important way to judge whether the general trend has changed. The specific law is that after a period of time (that is, at the depression stage), the depression stage falls back for more than the longest time before, and then the general trend often begins to change.

Fourthly, analyze the long and narrow fluctuation range.

In the narrow trading range of natural gas, if the natural gas futures price lasts for several weeks or months, and the natural gas price breaks through the original bottom or top, it largely means that the general trend has changed.
