KDJ index is a commonly used technical analysis index in financial markets. It provides the analysis results of overbought and oversold on the basis of calculating the closing price, highest price and lowest price of stocks, futures or currencies. When the KDJ index deviates from the top, it usually means that the stock price is close to the high point and may fall further.

KDJ Top Deviation is a market analysis technique, which can help traders find the best time to buy and sell stocks, futures or currencies. The core idea of this technology is to analyze the price trend according to some technical indicators in the market and predict the direction and intensity of future price changes. If the KDJ indicator shows that the price is now at a high level and is expected to fall, then this indicates a top deviation.

KDJ top divergence usually occurs before the price starts to fall, and is sometimes used together with other technical analysis indicators, such as bollinger bands and moving averages. This technology is an important market analysis tool, because it can provide timely warning when the market price is about to fall, so that traders can make trading strategies in advance and effectively control risks.
