通达信怎么把下面的代码改成选股器，我需要短牛，中牛，大牛都筛选出来

以下选股公式是可以同时选出小牛中牛大牛的公式：
N1:=5;
N2:=10;

LC:=REF(CLOSE,1);
RSI5:=SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*10,COLORFF00FF,LINETHICK1;
RSI10:=SMA(MAX(CLOSE-LC,0),N2,1)/SMA(ABS(CLOSE-LC),N2,1)*10,COLOR00FFFF;
VAR1:=C-REF(C,1);
VAR2:=100*EMA(EMA(VAR1,6),6)/EMA(EMA(ABS(VAR1),6),6);
MA5:=EMA(C,5);
MA13:=EMA(C,13);
UP:=DRAWLINE(L=LLV(L,BARSLAST(CROSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS
(MA13,MA5))+1),H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS
(MA5,MA13))+1),0),COLOR0000FF;
DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS
(MA5,MA13))+1),L=LLV(L,BARSLAST(CROSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS
(MA13,MA5))+1),0),COLOR00FF00;
BT:=(LLV(VAR2,2)=LLV(VAR2,7) AND COUNT(VAR2<0,2) AND CROSS(VAR2,MA(VAR2,2))) AND
REF(DOWN,1)REF(DOWN,1);
TJ1:=REF(DOWN,1)REF(DOWN,1) AND CHR:=HHV(HIGH,55);
HRY:=LLV(LOW,55);
HRY11:=HR*HRY;
HRY33:=SQRT(HRY11);
TJ2:=REF(DOWN,1)REF(DOWN,1) AND CXG:BT OR TJ1 OR TJ2;

该公式有未来函数，不适合做 选股公式！

真想找短牛，建议去副食商场牛肉专柜找一下。
