主题：测试正常的公式没有信号显示

我根据指南中单均线模型修改了其它公式，结果图表上没有信号显示，问题出在哪里呢？请明示。

单均线模型：

INPUT:N(15,1,100,1);
MAN:=MA(CLOSE,N);
SP :=TIME>=145500 OR (CLOSE<MAN AND BARSLAST(CROSS(MAN,CLOSE ))>=3);

BP :=TIME>=145500 OR (CLOSE>MAN AND BARSLAST(CROSS(CLOSE,MAN ))>=3);

BK :=TIME>=091500 AND TIME<145500 AND CLOSE>MAN AND BARSLAST(CROSS(CLOSE,MAN ))>=3;

SK :=TIME>=090000 AND TIME<145500 AND CLOSE<MAN AND BARSLAST(CROSS(MAN,CLOSE ))>=3; 
{平多} EXITLONG: SP,TFILTER;
{平空} EXITSHORT: BP,TFILTER;
{开多} ENTERLONG: BK,TFILTER;

{开空} ENTERSHORT: SK,TFILTER;

拟修改的模型修改前（可以正常操作）：
RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
K:=SMA(RSV,P1,1);
D:=SMA(K,P2,1);
{平多} EXITLONG: CROSS(d,k),ORDERQUEUE,TFILTER;
{平空} EXITSHORT: CROSS(k,d),ORDERQUEUE,TFILTER;
{开多} ENTERLONG: CROSS(k,d),ORDERQUEUE,TFILTER;

{开空} ENTERSHORT: CROSS(d,k),ORDERQUEUE,TFILTER;

修改后（无信号显示）：

RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
K:=SMA(RSV,P1,1);
D:=SMA(K,P2,1);
{平多} EXITLONG: CROSS(d,k)AND BARSLAST(CROSS(d,k))>=3,ORDERQUEUE,TFILTER;

{平空} EXITSHORT: CROSS(k,d)AND BARSLAST(CROSS(k,d))>=3,ORDERQUEUE,TFILTER;

{开多} ENTERLONG: CROSS(k,d)AND BARSLAST(CROSS(k,d))>=3,ORDERQUEUE,TFILTER;

{开空} ENTERSHORT: CROSS(d,k)AND BARSLAST(CROSS(d,k))>=3,ORDERQUEUE,TFILTER;
