通达信KDJ射线+选股指标（超买超卖型）指标公式

买卖信号

1. **抢反弹买入信号**：当K与D发生金叉（cross(K,D)），且乖离率BBIAS<-6，D<16，且收盘价>前一天收盘价时，出现抢反弹信号（图标9显示） 2. **底部动态买入信号**：当价格触及40日内最低价时，出现动态底部信号（红色粗条） 3. **KDJ射线选股信号**：当D<=21周期最低值，且趋势J1上穿趋势J2，且趋势J1>前一天值且<45时，出现选股信号 4. **卖出信号**：当BIAS21>=5，且V6上穿V5，且KDJ.J(34,3,3)>80且KDJ.J(9,3,3)>80时，出现卖出信号（绿色条）

用法

该指标为综合型超跌反弹指标，主要适用于： - **适用场景**：超跌反弹行情，当市场短期快速下跌后出现反弹机会时使用 - **抢反弹条件**：KDJ金叉+严重超跌（BBIAS<-6）+D值低位（<16）+收盘价上涨 - **注意事项**： - 该指标偏短线交易思路，风险较高 - 需要结合大盘环境和成交量综合判断 - 抢反弹信号属于左侧交易，需要严格止损 - 绿色卖出信号出现在KDJ高位钝化时，注意及时止盈
