底背离MACDKDJRSI原码

来函数检测结果如下：
该公式没有未来函数

DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26); 

DEA:=EMA(DIFF,9); 

A1:=BARSLAST(REF(CROSS(DIFF,DEA),1)); 

B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)<DIFF AND CROSS(DIFF,DEA); 

A2:=BARSLAST(REF(CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3)),1)); 

B2:=REF(C,A2+1)>C AND REF("KDJ.K"(9,3,3),A2+1)<"KDJ.K"(9,3,3) AND CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3)); 

A3:=BARSLAST(REF(CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24)),1)); 

B3:=REF(C,A3+1)>C AND REF("RSI.RSI1"(6,12,24),A3+1)<"RSI.RSI1"(6,12,24) AND CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24)); 

底背离:B1>0 OR B2>0 OR B3>0;

原理解析：
DIFF赋值:收盘价的12日指数移动平均 - 收盘价的26日指数移动平均


DEA赋值:DIFF的9日指数移动平均


A1赋值:上次1日前的DIFF上穿DEA距今天数


B1赋值:A1+1日前的C>C AND A1+1日前的DIFF

A2赋值:上次REF(CROSS("KDJ.K"(9,3,3距今天数,"KDJ.D"(9,3,3)),1))


B2赋值:A2+1日前的C>C AND REF("KDJ.K"(9,3,3),A2+1)<"KDJ.K"(9,3,3) AND CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3))


A3赋值:上次REF(CROSS("RSI.RSI1"(6,12,24距今天数,"RSI.RSI2"(6,12,24)),1))


B3赋值:A3+1日前的C>C AND REF("RSI.RSI1"(6,12,24),A3+1)<"RSI.RSI1"(6,12,24) AND CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24))
输出

底背离:B1>0 OR B2>0 OR B3>0
