KDJ

KDJ 指标是一种动量类技术指标，用于衡量市场的超买和超卖状态。它由三条线组成：

K线：反映当前价格相对于近期价格区间的位置；

D线：K线的平滑值；

J线：K与D的加权差值，用于增强动量信号。

当 J 线向上突破 D 线，常被视为买入信号；当 J 线向下跌破 D 线，则常被视为卖出信号。
该指标在震荡行情中较为有效，搭配其他趋势指标可提高可靠性。

KDJ Indicator is a momentum-based technical indicator used to assess overbought and oversold conditions in the market. It consists of three lines:

K Line: Shows the relative position of the current price within a recent high-low range.

D Line: A smoothed version of the K line.

J Line: An amplified difference between the K and D lines to highlight momentum.

When the J line crosses above the D line, it is typically considered a bullish (buy) signal; when it crosses below, it's seen as bearish (sell) signal.
This indicator performs well in ranging markets and can be more reliable when combined with trend-following indicators.
