DMI指标中DM的计算？？？

ABS

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(HD0 AND HDLD,HD,0),N);DMM:= SUM(IF(LD0 AND LDHD,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
