绝好的中线自用指标（100天，涨幅99.99%，成功率达95%以上）
公式编制思路：利用均线和MACD确定底部区域和启动点
公式源码：（主图）
A1:=3*eMA((C-LLV(L,30))/(HHV(H,30)-LLV(L,30))*100,5)-2*eMA((C-LLV(L,30))/(HHV(H,30)-LLV(L,30))*100,5);
A2:=LLV(L,21);
a3:LLV(L,30);
a4:=EMA(A1,5);
A5:=(HHV(H,34)-C)/(HHV(H,34)-LLV(L,34))*100;
a6:ma(c,20);
dif:="macd.diff"(12,26,9);
dea:="macd.dea"(12,26,9);
基础:=( dif<-0.1 and dif>dea),COLORyellow;
中线买入:CROSS(A1,a4)AND (A5-a4)>40 and 基础,COLORred;

中线:CROSS(A1,a4)AND (A5-a4)>40 and 基础;

关于DZH2使用问题：
因为DZH2的函数用法与DZH1不一样，不能直接引用，经过修改可以使用
DZH2公式源码：
A1:=3*eMA((C-LLV(L,30))/(HHV(H,30)-LLV(L,30))*100,5)-2*eMA((C-LLV(L,30))/(HHV(H,30)-LLV(L,30))*100,5);
A2:=LLV(L,21);
a3:LLV(L,30);
a4:=EMA(A1,5);
A5:=(HHV(H,34)-C)/(HHV(H,34)-LLV(L,34))*100;
a6:ma(c,20);
DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  :=EMA(DIFF,9);
基础:(diff<-0.1 and diff>dea);
中线买入:CROSS(A1,a4)AND (A5-a4)>40 and 基础;
STICKLINE(CROSS(A1,a4) AND (A5-a4)>40 and 基础 ,a3,a3*1.2,4,0),COLORRED;
