CYC指标做一个选股

编写要求：

要求cyc2上穿顶做出选股，再次感谢！！！！指标源码如下：cyc2:CYC(2);cyc13:cyc(13);cyc34:cyc(34);cyc0:MAXCYC,colorff9900;TY:=C;HD:=FILTER(BACKSET(FILTER(REF(TY,10)=HHV(TY,2*10+1),10),10+1),10);LD:=FILTER(BACKSET(FILTER(REF(TY,10)=LLV(TY,2*10+1),10),10+1),10); A:=REF(C,BARSLAST(HD));B:=REF(C,BARSLAST(LD));T1:=BARSLAST(HD)BARSLAST(LD) AND NOT(LD);顶:IF(T1,A,A),COLORFF00FF,POINTDOT,LINETHICK1;STICKLINE(T1,A,A,9,0),COLORFF00FF;底:IF(T2,B,B),COLOR80FF00,POINTDOT,LINETHICK1;RSV:=(CLOSE-LLV(LOW,13))/(HHV(HIGH,13)-LLV(LOW,13))*100;

解答：

TY:=C;
