6天内出现过，PDI线自下而上穿过MDI线，选股公式。 编写条件：编写方法：N:=14;M:=6;MTR:=SUM(MAX(MAX(HIGH-LOW,A(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),N);HD :=HIGH-REF(HIGH,1);LD :=REF(LOW,1)-LOW;DMP:=SUM(IF(HD>0&&HD>LD,HD,0),N);DMM:=SUM(IF(LD>0&&LD>HD,LD,0),N);PDI:= DMP*100/MTR;:= DMM*100/MTR;ADX:= MA(ABS(MDI-PDI)/(MDI+PDI)*100,M);ADXR:=(ADX+REF(ADX,M))/2;OSS(PDI,MDI);
