请老师把下面源码中 ——— 1：以“短J5”上穿“V30A”时（如下图H1红剑头所示）作为“B点”，以“短J5’”下穿“V30”时（如下图H2蓝剑头所示）作为“S点”写个可加到均线系统后的“BS买卖点”公式； 2：在“短J5”上拐时（如下图H3红剑头所示）写个条件选股；先谢！ 乖离率:=(C-MA(C,250))/MA(C,250)*100,COLOR00FFFF,LINETHICK2;MA乖离率5:=EMA(乖离率,5),COLOR4080FF;MA乖离率20:=EMA(乖离率,20),COLORRED;N1:=BARSLAST(CROSS(C,MA(C,250)));N2:=BARSLAST(CROSS(MA(C,250),C));长期趋势:=IF(N10,VAR1,0),COLORRED, LINESTICK;下跌浪: IF(VAR1<0,VAR2,0),COLOR00FF00,LINESTICK;S1:=V/MA(V,20);XG:IF(S1>2 AND C>REF(C,1) AND V>REF(V,1),30,0),STICK,COLORFFFFFF,LINETHICK2;DRAWTEXT(S1>2 AND C>REF(C,1) AND V>REF(V,1),40,'大'),COLORFF00FF;DRAWTEXT(S1>2 AND C>REF(C,1) AND V>REF(V,1),55,'量'),COLORFF00FF;

解答：

 乖离率:=(C-MA(C,250))/MA(C,250)*100,COLOR00FFFF,LINETHICK2;

MA乖离率5:=EMA(乖离率,5),COLOR4080FF;
MA乖离率20:=EMA(乖离率,20),COLORRED;
N1:=BARSLAST(CROSS(C,MA(C,250)));
N2:=BARSLAST(CROSS(MA(C,250),C));
长期趋势:=IF(N1<N2,N1+1,0),COLOR0000FF;
峰值乖离:=HHV(乖离率,长期趋势),COLOR00FF00;
N1A:=BARSLAST(CROSS(C,MA(C,13)));
N2A:=BARSLAST(CROSS(MA(C,13),C));
短线跟踪:IF(N1A<N2A,N1A+1,0),COLORFFFFFF,LINETHICK1,LINESTICK;
V0:0,COLORFFA2AF;
RSV5:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100-50;
短K5:=SMA(RSV5,3,1);
短D5:=SMA(短K5,3,1);
短J5:3*短K5-2*短D5,COLORAAAAAA;
RSV27:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100-50;
中K27:SMA(RSV27,3,1),LINETHICK3,COLORFFFFFF;
RSV89:=(CLOSE-LLV(LOW,89))/(HHV(HIGH,89)-LLV(LOW,89))*100-50;
