编写要求：

请老师帮我把好公式中的出现紫色柱做个选股公式，谢谢！源码：X5:=EXPMA(CLOSE,3);X10:=EXPMA(CLOSE,7);X20:=EXPMA(CLOSE,20);五日斜率:=(X5-REF(X5,1))*100/REF(X5,1),LINETHICK2,COLORYELLOW;十日斜率:=(X10-REF(X10,1))*100/REF(X10,1),LINETHICK2,COLORBLUE;二十斜率:=(X20-REF(X20,1))*100/REF(X20,1),LINETHICK2,COLORWHITE;XX5:=XMA(五日斜率,4),LINETHICK2,COLORYELLOW;XX10:=XMA(十日斜率,7),LINETHICK2,COLORBLUE;XX200:=XMA(二十斜率,20);AA1:=XX200>=0.7 AND REF(XX200,1) XX10 AND XX10>XX200 AND REF(XX5,2)=0.7 AND REF(XX200,1) XX10 AND XX10>XX202 AND REF(XX5,2)=0.7 AND REF(XX200,1) XX10 AND XX10>XX204 AND REF(XX5,2)=0.7 AND REF(XX200,1) XX10 AND XX10>XX206 AND REF(XX5,2)=0.7 AND REF(XX207,1)=0.7 AND REF(XX2071,1)=0.7 AND REF(XX2072,1)=0.7 AND REF(XX208,1)=0.7 AND REF(XX2081,1)=0.7 AND REF(XX2082,1)

解答：

X5:=EXPMA(CLOSE,3);
