网友求助：
我的意思是 在同一天 里 PDI 上穿那三线的预警 谢谢老师了
N 14 2 100 1
M 6 1 100 1
TR := SUM(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(LOW-REF(CLOSE,1))),N);
HD := HIGH-REF(HIGH,1);
LD := REF(LOW,1)-LOW;
DMP:= SUM(IF(HD>0 AND HD>LD,HD,0),N);
DMM:= SUM(IF(LD>0 AND LD>HD,LD,0),N);
PDI: DMP*100/TR;
mdi: DMM*100/TR;
ADX: MA(ABS(MDI-PDI)/(MDI+PDI)*100,M);
ADXR:(ADX+REF(ADX,M))/2;
解答如下：
N 14 2 100 1
M 6 1 100 1
M 6 1 100 1
TR := SUM(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(LOW-REF(CLOSE,1))),N);
HD := HIGH-REF(HIGH,1);
LD := REF(LOW,1)-LOW;
DMP:= SUM(IF(HD>0 AND HD>LD,HD,0),N);
DMM:= SUM(IF(LD>0 AND LD>HD,LD,0),N);
PDI:= DMP*100/TR;
MDI:= DMM*100/TR;
ADX:= MA(ABS(MDI-PDI)/(MDI+PDI)*100,M);
ADXR:=(ADX+REF(ADX,M))/2;
cross(pdi,mdi) and cross(pdi,adx) and cross(pdi,adxr);
