Looking at the 4H chart of Dogecoin, you can find a textbook-like support and resistance operation pattern. Many people tend to understand support and resistance as rigid lines, but in fact, they are dynamic price zones. Why is that? Because both bulls and bears keep testing and repeatedly failing to break through key levels, ultimately forming a support and resistance zone with some tolerance. Each failure during these tests validates the effectiveness of this zone. Once you understand this, you'll be able to judge the true support and resistance levels of the price more flexibly.
