DRAWICON(CROSS(AD,AK) AND AK<BK AND DOWNNDAY(MA(C,18),1),AD+15,12);
 

{公式在线提供：www.gszx.com.cn}答案：

DRAWICON(CROSS(AK,AD) AND (O+C)/2>REF((O+C)/2,1),AD-10,7);
DRAWICON(CROSS(AD,AK) AND AK<BK AND MA(C,18)<REF(MA(C,18),1),AD+15,8);

或

DRAWICON(CROSS(AK,AD) AND ALL((O+C)/2>REF((O+C)/2,1),1),AD-10,7);
DRAWICON(CROSS(AD,AK) AND AK<BK AND ALL(MA(C,18)<REF(MA(C,18),1),1),AD+15,8);
