我目前正在修改从互联网下载的烛台形态指标。
我在看跌吞没模式下添加了附加条件，即当前柱 (HL) 的范围必须大于前 6 根蜡烛的范围。
附加代码为：((H - L) > (H1 - L1) && (H2 - L2) && (H3 - L3) && (H4 - L4) && (H5 - L5) && (H6 - L6)))
当然，如果我添加这个，我必须声明额外的 H4、H5、H6、L4、L5 L6 变量（我做了：双 O、O1、O2、C、C1、C2、L、L1、L2、L3、 L4、L5、L6、H、H1、H2、H3、H4、H5、H6；）
另外，我还添加了 int shift3; 换档4；ETC
但是，为什么指标不记录条件：当前柱 (HL) 的范围必须大于前 6 根蜡烛的范围？
