最好用的精品DMI指标，用于逃顶抄底很有用哦！
N=10 MM=4
MTR:=EXPMEMA(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:=EXPMEMA(IF(HD>0&&HD>LD,HD,0),N);
DMM:=EXPMEMA(IF(LD>0&&LD>HD,LD,0),N);
PDI: DMP*100/MTR;
MDI: DMM*100/MTR;
ADX: EXPMEMA(ABS(MDI-PDI)/(MDI+PDI)*100,MM);
ADXR:EXPMEMA(ADX,MM);
