From now on, in the evening trading review articles, I will incorporate technical trend analysis. These analytical logic are open for everyone to reference and verify— the key is to learn the thinking process, not to rush into copying trades. Over the past six years, I have continuously documented trading reviews, market retrospectives, and coin research, accumulating a number of frameworks and methodologies for stock (coin) selection. Instead of hiding them away, I prefer to systematically share this logical system to help genuinely interested traders understand the decision-making chain behind it. Technical indicators will be explained, market structures will be analyzed, and the dimensions of coin selection will also be broken down—those with the intention will naturally be able to extract their own trading system from it.
