For example, the technical analysis knowledge of reading pictures and telling stories afterwards is simply not needed or learned. For example, stocks have gone up, and what indicators are said to have gone up because of the golden cross of indicators. But the principle here, taking kd indicator as an example, calculates rsv according to the proportional relationship between the highest price, the lowest price and the final closing price in a 9-day period, and then obtains the k.d value by using the moving average method, that is to say, the graph of kd indicator only appears after the price changes. It is completely wrong to analyze the stock order with technical indicators. Looking at the picture afterwards, we can say that everything is right. For prior judgment, the error rate is high.

The core of technical analysis is to judge which step the main force will take and what the probability will be by the traces left by the main force in and out of the stock on the K-line volume. This is technical analysis.

Technical analysis can be correct with a high probability, but it can't be 100% correct, so it is necessary to deal with small probability errors with discipline, that is, scientific stop-loss strategies, so as to avoid the possibility of big losses.

As for books, there are basically no books. Most of the technical analysis textbooks were born hundreds to decades ago. Without trading volume and financial derivatives such as futures options, they cannot be used in modern stock markets without adjustment. But the people who translate these books basically don't understand stocks and won't adjust them at all. You will take detours when you study.
