修改一个选股公式，出现笑脸时选股

编写要求：

n1:=16;P:=5;LC := REF(CLOSE,1);RSI:=SMA(MAX(CLOSE-LC,0),n1/2,1)/SMA(ABS(CLOSE-LC),N1/2,1)*100,COLORWHITE;RSI1:SMA(MAX(CLOSE-LC,0),n1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORRED,LINETHICK2;RSI2:=SMA(MAX(CLOSE-LC,0),n1*2,1)/SMA(ABS(CLOSE-LC),N1*2,1)*100,COLORAAAA00;PARTLINE(RSI1<50,rsi1),COLOR00bb00,LINETHICK2;短趋势:=Ema(RSI,N1/3),COLORYELLOW,LINEDOT;中趋势:Ema(RSI1,N1/2),COLORAAAA00,COLORMAGENTA,LINEDOT;A1:=REF(RSI1,P)=HHV(RSI1,2*P+1);B1:=FILTER(A1,P);C1:=BACKSET(B1,P+1);D1:=FILTER(C1,P);{高点}A2:=REF(RSI1,P)=LLV(RSI1,2*P+1);B2:=FILTER(A2,P);C2:=BACKSET(B2,P+1);D2:=FILTER(C2,P);{低点}上:REF(RSI1,BARSLAST(D1)),COLORFF00FF,LINETHICK;下:REF(RSI1,BARSLAST(D2)),COLOR00FF00,LINETHICK;向上:CROSS(RSI1,上*1.01),LINETHICK;相对能量:(RSI1-(上+下)/2)/(上+下)/2*100,LINETHICK;STICKLINE(相对能量>0,50,相对能量+50,2,0),COLORRED;STICKLINE(相对能量<0,50,相对能量+50,2,0),COLORCYAN;R11:=BACKSET(ISLASTBAR,BARSLAST(D1)+1); S11:=R11>REF(R11,1);DRAWLINE(D1,RSI1,S11,RSI1,1),COLORYELLOW;T11:=BACKSET(ISLASTBAR,BARSLAST(D2)+1);U11:=T11>REF(T11,1);DRAWLINE(D2,RSI1,U11,RSI1,1),COLOR00FF00;STICKLINE(C>0,下,下,1,0),COLOR00FF00;STICKLINE(C>0,上,上,1,0),COLORFF00FF;DRAWTEXT(CROSS(RSI1,上*1.01),上,'★'),COLORRED,ALIGN0;DRAWTEXT(CROSS(下*0.99,RSI1),下,'★'),COLORGREEN,ALIGN0;DRAWICON(D1,RSI1,2);DRAWICON(D2,RSI1,1); 20;50;80;

解答：

 n1:=16;P:=5;
