我把通达信的DMI指标公式移植到金字塔，可是EXPMEMA函数在金字塔里面不能识别，出现语法错误。请问你们可以解决吗？附通达信程序：MTR:=EXPMEMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),14);
HD :=HIGH-REF(HIGH,1);
LD :=REF(LOW,1)-LOW;
DMP:=EXPMEMA(IF(HD>0&&HD>LD,HD,0),14);
DMM:=EXPMEMA(IF(LD>0&&LD>HD,LD,0),14);
PDI: DMP*100/MTR;
MDI: DMM*100/MTR;
ADX: EXPMEMA(ABS(MDI-PDI)/(MDI+PDI)*100,6);
ADXR:EXPMEMA(ADX,6);
另外，金字塔DMI程序：TR1 := SUM(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(LOW-REF(CLOSE,1))),P);
HD := HIGH-REF(HIGH,1);
LD := REF(LOW,1)-LOW;
DMP:= SUM(IF(HD>0 AND HD>LD,HD,0),P);
DMM:= SUM(IF(LD>0 AND LD>HD,LD,0),P);
PDI: DMP*100/TR1;
MDI: DMM*100/TR1;
ADX: MA(ABS(MDI-PDI)/(MDI+PDI)*100,M);
ADXR:(ADX+REF(ADX,M))/2
