RSI红绿多空波段金叉死叉提示通达信公式 副图 测试图

来函数检测结果如下：
该公式没有未来函数

SJ:=1;

超买:100*SJ,COLORRED,POINTDOT;

超卖:0*SJ,COLOR00FF00,POINTDOT;

LC :=REF(CLOSE,1);

RSI1:SMA(MAX(CLOSE-LC,0)*SJ,7,1)/SMA(ABS(CLOSE-LC),7,1)*100;

RSI2:SMA(MAX(CLOSE-LC,0)*SJ,14,1)/SMA(ABS(CLOSE-LC),14,1)*100;

IF(RSI1<=REF(RSI1,1),RSI1,DRAWNULL),LINETHICK2,COLORGREEN;

IF(RSI1>=REF(RSI1,1),RSI1,DRAWNULL),LINETHICK2,COLORRED;

IF(RSI2<=REF(RSI2,1),RSI2,DRAWNULL),LINETHICK2,COLORGREEN;

IF(RSI2>=REF(RSI2,1),RSI2,DRAWNULL),LINETHICK2,COLORRED;

DRAWTEXT(CROSS(RSI1,RSI2) AND RSI1<35,20,'金叉'),COLORMAGENTA;

DRAWTEXT(CROSS(RSI2,RSI1) AND RSI1>65,60,'死叉'),COLORBLUE;

 

原理解析：
SJ赋值:1
输出超买:100*SJ,画红色,POINTDOT
输出超卖:0*SJ,COLOR00FF00,POINTDOT
LC :=1日前的收盘价
输出RSI1:SMA(收盘价-LC和0较大值*SJ,7,1)/SMA(收盘价-LC的绝对值,7,1)*100
输出RSI2:SMA(收盘价-LC和0较大值*SJ,14,1)/SMA(收盘价-LC的绝对值,14,1)*100
