通达信公式kdj叠加布林线源码如下：
上轨:SMA(SMA(HHV(HIGH,9),3,1),3,1),{COLORGREEN};
下轨: SMA(SMA(LLV(LOW,9),3,1),3,1),{COLORYELLOW};
K:SMA(C,3,1),{COLORMAGENTA};
D: SMA(K,3,1),COLORWHITE;
IF(上轨>=REF(上轨,1),上轨,DRAWNULL),COLORRED,LINETHICK1;
IF(上轨<REF(上轨,1),上轨,DRAWNULL),COLORGREEN,LINETHICK1;
IF(下轨>=REF(下轨,1),下轨,DRAWNULL),COLORRED,LINETHICK1;
IF(下轨<REF(下轨,1),下轨,DRAWNULL),COLORGREEN,LINETHICK1;
IF(K>=REF(K,1),K,DRAWNULL),COLORMAGENTA,LINETHICK2;
IF(K<REF(K,1),K,DRAWNULL),COLORYELLOW,LINETHICK2;
IF(D>=REF(D,1),D,DRAWNULL),COLORFFFF00,LINETHICK1;
IF(D<REF(D,1),D,DRAWNULL),COLORBROWN,LINETHICK2;
DRAWTEXT(CROSS(K,D),D,'Ｂ'),COLORRED;
DRAWTEXT(CROSS(D,K),D,'Ｓ'),COLORYELLOW;
