DMI中ADX和ADXR值相差相差正負0.5之間的指標源碼？

M:=6;

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;

ADX-ADXR<0.5 AND ADX-ADXR>-0.5;
