What are support levels and resistance levels?

At the most basic level, supports and resistance are very simple concepts. When the price is at a level that cannot be broken, this level is an obstacle to some extent. Supporting means that the price reaches the "floor", while resistance means that the price reaches the "ceiling". Basically, you can think of the supporting zone as the demand zone and the resistance zone as the supply zone.
While support and resistance have traditionally been represented in lines, the reality is often less precise. Remember: the market is not driven by the laws of physics that prevent the market from breaking through a certain level. Because of this, it is more appropriate to think of supports and resistance as zones. You can think of these areas as ranges on the price chart, and they may push traders to increase their activity.
Let's look at an example of a support level. We notice that the price keeps moving into the area where the asset is being bought. When this area is tested long times, a support range is formed. Since the shorts (sellers) are unable to push the price further down, the price eventually rebounds — possibly starting a new rise. （p1）
Now let's look at the resistance level. As we can see, the price is trending downward. But after each rebound, it failed to break through the same area longing. The resistance level is formed because the long heads (buyers) cannot control the market and push the price upwards to pump, causing the downward trend to continue. （p2）
