编写条件：
JJ :=(C*3+H+L+O)/6; SK := EMA(JJ,13) - EMA(JJ,21); SD := EMA(SK,3); SP := EMA(SK,10); A1:=EMA(C,7)-EMA(C,21); B1:=EMA((0.668*REF(A1,1)+0.333*A1),1); MACD:B1,COLORSTICK; 持股:IF(A1>=B1,A1,B1),COLORYELLOW,LINETHICK2; 持币:IF(B1-A1,B1,A1),COLORGREEN,LINETHICK2; 请老师把红绿柱加长和缩短改成能变颜色的，看着直观一点，再改一个macd加长和缩短的选股公式，谢谢老师了，我等很久了，太需要了。。。编写方法：
{红绿柱加长和缩短改成能变颜色用图标实现}
