{════ 通达信 · 技术指标 海底捞月 (副图) ════
  安装: 公式管理器 -> 技术指标 -> 新建 -> 名称 海底捞月 -> 画线方法:副图 -> 粘贴 -> 确定
  图上怎么看:
    B = 出手: 买点(收盘确认, 次日开盘买)
    G = 深筛优先: 更强的出手, 同一天多只票时优先买它(有G的日子不显示B)
    黄橙空心柱 = 观察: 只看不买
    黄橙实心柱 = 关注: 准备, 还不买
    红色实心柱 = 提示: 接近出手
    绿柱 = 离场: 收盘WZ20>=60, 次日开盘卖 (绿柱才是顶)
    紫柱 = 热度: 有人买/正在过热, 只是预警不是顶
    灰柱 = 灾难线: 跌破-30%
  两条线: 红=得分线(极端度), 黄橙=超跌深度线
  配色(2026-10-18 第7版·提亮, 两平台同色): 红#FF4D4D 金#FFB830 绿#35D672 墨绿#26BE66 紫#E040FB
    B=绿字(#35D672) G=墨绿字(#26BE66) 灰=门槛线/灰柱
