趋向指标(钱龙)公式：

TR := SMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(LOW-REF(CLOSE,1))),N,1);

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

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

DMP:= SMA(IF(HD>0 AND HD>LD,HD,0),N,1);

DMM:= SMA(IF(LD>0 AND LD>HD,LD,0),N,1);

PDI: DMP*100/TR;

MDI: DMM*100/TR;

ADX: SMA(ABS(MDI-PDI)/(MDI+PDI)*100,N,1);

ADXR:(ADX+REF(ADX,M))/2
