鉴定该指标有无未来-通达信答疑

	编写条件： TR:=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; A7:=C-REF(C,1); A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6); SHORT:=7; LONG:=19; RMA:=EMA(CLOSE,SHORT); NMA:=EMA(CLOSE,LONG); UP:=DRAWLINE(L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),0); DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0); 买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2))) AND REF(DOWN,1)REF(DOWN,1),STICK,COLORBLUE,LINETHICK3; DRAWTEXT(买进,0.5,'买进'),COLORRED; 请鉴定该指标有无未来 如果没未来请老师做个选股公式 谢谢 编写方法：  指标有未来 那就不用做选股了，O(∩_∩)O哈哈~
