主题：选股公式问题

 你这没啥好改的啊。只需要去掉后台交易语句

把交易的条件作为选股条件就行了。

DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA),COLORSTICK;

N:=BARSLAST(CROSS(DIFF,DEA))+1;
N1:=BARSLAST(CROSS(DEA,DIFF))+1;
DIFF1:=REF(REF(DIFF,N-1),1);
DIFF2:=REF(REF(DIFF,N1-1),1);
C1:=REF(REF(C,N-1),1);
C2:=REF(REF(C,N1-1),1);
DBL1:DIFF and  DIFF1 AND CROSS(DIFF,DEA) AND C and C1; //底背离
DBL:DIFF and DIFF2 AND  CROSS(DEA,DIFF) AND C and   C2; //顶背离

按照交易语句的思路是底背离买入，那你选股时候选择 DBL1作为选股条件即可。
