网友求助：
飘带变红为买点
INPUT: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,LINETHICK1,COLOR000099;
ADXR:EMA(ADX,M),LINETHICK0,Color008000;
ADMA:EMA(ADX,M1),LINETHICK1,COLORCCCCCC,LAYER0;
OMD:(ADX-2*ADMA+ADXR)/2,LINETHICK0;
PARTLINE(110,1),ColorA6A600,LAYER0;
PARTLINE(0,1),Color008080,LAYER0;
PARTLINE(-110,1),ColorA6A600,LAYER0;
FILLRGN(ADX,ADXR,ADX>=ADXR),Color000044;
FILLRGN(ADX,ADXR,ADX<ADXR),Color004400;
STICKLINE(OMD>REF(OMD,1) AND OMD>0,0,OMD,4,0),COLOR4444FF;
STICKLINE(OMD>REF(OMD,1) AND OMD<0,0,OMD,4,0),COLORFF33FF;
STICKLINE(OMD<REF(OMD,1),0,OMD,4,0),COLOR66CC66;
PARTLINE(ADX,ADX>=ADXR),COLOR0000CC,LINETHICK1;
PARTLINE(ADX,ADX<ADXR),COLOR008800,LINETHICK1;
解答如下：
INPUT: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);
CROSS(ADX,ADXR);
