做KD共振指标白色和绿色下穿或上穿的选股

编写要求：

"下穿公式"一：指标线白色和绿色线60以上下穿红色和黄色线。思路：副图指标白色和绿色线高位【比如60以上】同时下穿红色和黄色线，下穿即卖出提示。 “上穿公式”二：指标白色和绿色线在25以下上穿红色和黄色线。思路：同上，上穿即买入提示。 源码【感谢源码作者】 VAR13:=(CLOSE-LLV(LOW,13))/(HHV(HIGH,13)-LLV(LOW,13))*100; K13:SMA(VAR13,3,1), COLORWHITE; D13:=SMA(K13,3,1), COLORWHITE; VAR21:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100; K21:SMA(VAR21,3,1), COLORGREEN; D21:=SMA(K21,3,1), COLORGREEN; VAR34:=(CLOSE-LLV(LOW,34))/(HHV(HIGH,34)-LLV(LOW,34))*100; K34:SMA(VAR34,3,1), COLORYELLOW; D34:=SMA(K34,3,1), COLORYELLOW; VAR55:=(CLOSE-LLV(LOW,55))/(HHV(HIGH,55)-LLV(LOW,55))*100; K55:SMA(VAR55,3,1),COLORRED; D55:=SMA(K55,3,1),COLORRED; DIBU:= K13<20 AND D13<20 AND K21<20 AND D21<20 AND K34<20 AND D34<20 AND K55<20 AND D55<20; TOBU:= K13>80 AND D13>80 AND K21>80 AND D21>80 AND K34>80 AND D34>80 AND K55>80 AND D55>80; 感谢千钧老师批评指导，谢谢！！
