In cryptocurrency trading, all the trends you've seen boil down to two types: trending and consolidating. Trends can be further divided into uptrends and downtrends. Sounds simple, right? But such a simple classification is the very foundation of all technical analysis.

This conclusion is not made up out of thin air. It is summarized from countless charts and numerous practical battles, step by step. Because it is hard-won, most people tend to overlook it. They rush to learn various indicators and complex trading systems, only to get deeper and deeper into trouble. Little do they realize that without understanding the basics, even the most dazzling systems are useless.

Many people know the saying "all levels of trends can be broken down into trends and consolidations," but they only stay at the level of knowing, without truly delving into it. It appears to be a static observation, but if you can transform it into a dynamic, actionable understanding, it results in a qualitative leap.

This leads to the most core principle: any trend of any level, of any type, must eventually complete. In simpler terms — **Trend Completion**.

The beauty of this principle lies in turning those static theories, which are difficult to apply directly, into dynamic tools that can be truly used in practice. Once the foundation is solid, indicators and trading systems are really no big deal. Conversely, if the foundation wobbles, no amount of tools can save you.
