网友求助：

TRA:=EMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),3);

HD:=HIGH-REF(HIGH,1);

LD:=REF(LOW,1)-LOW;

DMP:=EMA(IF(HD>0&&HD>LD,HD,0),3);

DMM:=EMA(IF(LD>0&&LD>HD,LD,0),3);

PDI:=DMP*100/TRA;

MDI:=DMM*100/TRA;

ADX:=EMA(ABS(MDI-PDI)/(MDI+PDI)*100,2);

OK:PDI<1 AND ADX>90;





解答如下：

TRA:=EMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),3);

HD:=HIGH-REF(HIGH,1);

LD:=REF(LOW,1)-LOW;

DMP:=EMA(IF(HD>0&&HD>LD,HD,0),3);

DMM:=EMA(IF(LD>0&&LD>HD,LD,0),3);

PDI:=DMP*100/TRA;

MDI:=DMM*100/TRA;

ADX:=EMA(ABS(MDI-PDI)/(MDI+PDI)*100,2);

OK:=PDI<1 AND ADX>90;

OK=1;
