用DMI新编的MACD出现底背离公式加个背离画线条件

各位老师好，请将DMI新编的MACD出现底背离时候加个自动画线， 源码：N:=21;M:=6;M1:=20; TR1:=EMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),N); HD :=HIGH-REF(HIGH,1); LD :=REF(LOW,1)-LOW; DMP:=EMA(IF(HD>0 AND HD>LD,HD,0),N); DMM:=EMA(IF(LD>0 AND LD>HD,LD,0),N); PDI:= DMP*100/TR1; MDI:= DMM*100/TR1; ADX: EMA((PDI-MDI)/(MDI+PDI)*100,M)*2; ADXR:EMA(ADX,M); ADMA:EMA(ADX,M1); OMD:(ADX-2*ADMA+ADXR)/2, COLORSTICK; DRAWBAND(ADX,RGB(155,50,50),ADXR,RGB(0,100,50)); STICKLINE(OMD>REF(OMD,1) AND OMD>0,0,OMD,1,0),COLORRED; STICKLINE(OMD>REF(OMD,1) AND OMD0 AND OMD-REF(OMD,1)>0,30,0); {OMD;} 110; 0; -110;

N:=21;M:=6;M1:=20;

TR1:=EMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),N);

HD :=HIGH-REF(HIGH,1);

LD :=REF(LOW,1)-LOW;

DMP:=EMA(IF(HD>0 AND HD>LD,HD,0),N);

DMM:=EMA(IF(LD>0 AND LD>HD,LD,0),N);

PDI:= DMP*100/TR1;

MDI:= DMM*100/TR1;

ADX: EMA((PDI-MDI)/(MDI+PDI)*100,M)*2;

ADXR:EMA(ADX,M);

ADMA:EMA(ADX,M1);

OMD:(ADX-2*ADMA+ADXR)/2, COLORSTICK;

DRAWBAND(ADX,RGB(155,50,50),ADXR,RGB(0,100,50));

STICKLINE(OMD>REF(OMD,1) AND OMD>0,0,OMD,1,0),colorred;

STICKLINE(OMD>REF(OMD,1) AND OMD<0,0,OMD,1,0),colorgreen;

STICKLINE(OMD<REF(OMD,1),0,OMD,1,0),COLORCBCBC0;

STICKLINE(OMD>=0 OR OMD<=0,0,0,50,1),colorwhite;

ADX1:ADX,colorred;

ADXR1:ADXR,colorgreen;

ADMA1:ADMA;

A1:= BARSLAST(REF(CROSS(ADX,ADXR),1));

底背离:=REF(C,A1+1)>C AND ADX>REF(ADX,A1+1) AND CROSS(ADX,ADXR) AND ADXR<0;

DRAWLINE(A1=0,ADXR,底背离,ADXR,0),COLORFFFFFF,LINETHICK2;

STICKLINE(底背离,ADXR,0,0.5,0),COLORFFFFFF;

DRAWTEXT(底背离,ADXR,'底背离'),COLORFFFFFF;

强:IF(ADX1>=ADXR1,ADX1,DRAWNULL),colorred,LINETHICK3;

买入:IF(OMD>0 AND OMD-REF(OMD,1)>0,30,0);
