出现红柱处写一选股公式.谢谢 A1:=REF(CLOSE,2); A2:=SMA(MAX(CLOSE-A1,0),7,1)/SMA(ABS(CLOSE-A1),7,1)*100; 阶段底部:IF(A2<19,2,0); AA:=(CLOSE-LLV(LOW,23))/(HHV(HIGH,23)-LLV(LOW,23))*100; BB:=MA(AA,10); 趋势线:=SMA(BB,3,1)/10; 底部线:=(HHV(HIGH,34)/LLV(LOW,34)); 进入底部:IF(CROSS(底部线,趋势线),10,0); 冲出底部:IF(CROSS(趋势线,底部线),10,0); 趋势:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1),COLORYELLOW; 底部:=10; 猎杀潜航:IF(CROSS(趋势,底部),10,0),STICK,COLORRED,LINETHICK3;
股票网解答：
趋势:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
XG:CROSS(趋势,10);
