KDJ背离与共振提示指标(源码)
这条指标把KDJ、RSI、MACD和DMI这4套背离放进同一个画面：价格与指标走反方向时，用M、K、R、D这4个字母在最低价下方或最高价上方标出底背与顶背，再配合柱体把信号分区。
逻辑
随机值先按9周期取样，做2次3周期平滑得到快慢线；2条线金叉时记下底背的锚点，死叉时记下顶背的锚点。
相对强弱取6周期与24周期这2条，相减得到一条摆动线，柱体跟着摆动线的正负换色。
背离判定看价格与指标的反向。当前价格比上一次金叉时更低、指标反而更高，就算一次底背；反向就是顶背。
MACD用12与26周期的指数均线之差作快线，9周期平滑作慢线，同样各判一次背离。
DMI用14周期的真实波幅拆出正负方向线，配合同样的锚点比较，得到方向上的背离。
标记上，底背用字母写在最低价下方，顶背写在最高价上方，同时在参考线的上下沿画出柱体区分。
参数微调
9、3是随机值的取样与平滑周期，改大快慢线更钝。
6、12、24是相对强弱的3档周期，改小摆动线更灵敏。
12、26、9是MACD的快慢与信号周期，改小金叉更频繁。
