预警公式条件：第一、PDI大于ADX且同时大于ADXR和MDI；第二、ADX上穿ADXR成金叉第三、PDI数值大于25；以上条件同时满足的预警公式，望解答。DMI源码如下：参数：N＝ 2 90 14 M= 2 60 6TR:=EXPMEMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(REF(CLOSE,1)-LOW)),N);HD :=HIGH-REF(HIGH,1);LD :=REF(LOW,1)-LOW;DMP:=EXPMEMA(IF(HD>0&&HD>LD,HD,0),N);DMM:=EXPMEMA(IF(LD>0&&LD>HD,LD,0),N);PDI: DMP*100/TR;MDI: DMM*100/TR;ADX: EXPMEMA(ABS(MDI-PDI)/(MDI+PDI)*100,M);ADXR:EXPMEMA(ADX,M); 编写条件：编写方法：&np;N:=14;M:=6;TR1:=EXPMEMA(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))
