請老師改為“買”“賣”“跟”“絕佳”四個選股公式，不勝感激！

VA2:=EMA(C,20);

JJ:=(O+H+L)/3;

智能黃金線:=EMA(JJ,4);

買:CROSS(VA1,VA2)AND(C>=O)AND 智能黃金線>REF(智能黃金線,1);

==============

賣:CROSS(REF(ZIG(3,10),1),ZIG(3,10)){未來函數，慎用};

==================

箱頂:=MA(REF(HHV(C,30),1),2);

買線:=EMA(C,2);

賣線:=EMA(SLOPE(C,21)*20+C,42);

跟:CROSS(買線,賣線)AND 箱頂>=REF(箱頂,1);

===============

絕佳:CROSS(ZIG(3,8),REF(ZIG(3,8),1)){未來函數，慎用};
