為什么效果預覽的時候出現(xiàn)如下錯誤　[文華財經]

B是一個參數(shù)嗎？您的模型語法和邏輯思路并不完善，請參考以下修改：

N:=BARSLAST(DATE<>REF(DATE,1))+1;
HH:=REF(HHV(H,B),B);
LL:=REF(LLV(L,B),B);
CC:=REF(C,B);//
RSV:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100;
K:=SMA(RSV,5,6);
D:=SMA(K,4,1);
WR:=-100*(HHV(HIGH,14)-CLOSE)/(HHV(HIGH,14)-LLV(LOW,14));
SARLINE:=ABS(SAR(4,0.02,0.2));
COND1:=MAX(HH-CC,CC-LL);//
COND2:=0.1*COND1;
TOP:=REF(O,B-1)+COND2;//
BOTTOM:=REF(O,B-1)-COND2;
CROSS(C,TOP)&&TIME>=0930&&TIME<1455 || K>D&&D>20 && WR<-90 && CROSS(CLOSE,SARLINE),BK;
CROSS(BOTTOM,C)&&TIME>=0930&&TIME<1455|| K<D&&D<80 && WR<-10 && CROSS(SARLINE,CLOSE),SK;
TIME>=1455,SP;
TIME>=1455,BP;
AUTOFILTER;

注意設置參數(shù)后，您測試看看是否還有上述問題，如果有，請告知具體加載的合約，周期和K線根數(shù)，我們測試核實；

第一句是當天開盤至今的K線根數(shù)，N改為B試試：

B:=BARSLAST(DATE<>REF(DATE,1))+1;
BB:=REF(B,B);
