请教通达信选股公式：N日均线呈近似水平线向前延伸（即均线走平）

Question

如果通用的公式不好编，就请编120日和250日均线走平的两个公式吧，先谢谢了。公式测试务必能通过并确实能选出符合条件的股票啊

Answer 1

N日均线呈近似水平线：
N:=5;
MA2:=MA(C,240);
HH2:=HHV(MA2,N);
LL2:=LLV(MA2,N);
XG:BETWEEN((HH2-LL2)/MA2,0,0.001);

120日和250日均线走平：
N:=5;
MA1:=MA(C,120);
MA2:=MA(C,240);
HH1:=HHV(MA1,N);
LL1:=LLV(MA1,N);
HH2:=HHV(MA2,N);
LL2:=LLV(MA2,N);
XG:BETWEEN((HH1-LL1)/MA1,0,0.001) AND BETWEEN((HH2-LL2)/MA2,0,0.001);
