+
+## 已实现：边界利用率分数（2026-01-27）
+
+### 问题分析
+
+观察图中 SZ002748 世龙实业：
+- 宽度比：0.12（非常收敛）
+- 强度分：0.177（排名第三）
+- 但肉眼观察：价格走势与三角形边界之间有**大量空白**
+
+**原因**：
+- 原权重：收敛分 20%、拟合贴合度 15%
+- 当宽度比 0.12 时，收敛分 = 1 - 0.12 = 0.88
+- 收敛分贡献 = 0.20 × 0.88 = 0.176 ≈ 全部强度分
+- **收敛分只衡量"形状收窄"，不衡量"价格是否贴近边界"**
+
+### 解决方案
+
+新增**边界利用率**分数，衡量价格走势对三角形通道空间的利用程度。
+
+### 新增函数
+
+```python
+def calc_boundary_utilization(
+    high, low,
+    upper_slope, upper_intercept,
+    lower_slope, lower_intercept,
+    start, end,
+) -> float:
+    """
+    计算边界利用率 (0~1)
+    
+    对窗口内每一天：
+    1. 计算价格到上下边界的距离
+    2. 空白比例 = (到上沿距离 + 到下沿距离) / 通道宽度
+    3. 当日利用率 = 1 - 空白比例
+    
+    返回平均利用率
+    """
+```
+
+### 新权重配置
+
+| 分量 | 原权重 | 新权重 | 说明 |
+|------|--------|--------|------|
+| 突破幅度 | 50% | **50%** | 不变 |
+| 收敛分 | 20% | **15%** | 降低 |
+| 成交量分 | 15% | **10%** | 降低 |
+| 拟合贴合度 | 15% | **10%** | 降低 |
+| **边界利用率** | - | **15%** | 新增 |
+
+### 空白惩罚（新增）
+
+为避免“通道很宽但价格很空”的误判，加入空白惩罚：
+![](images/2026-01-27-18-49-33.png)
+![](images/2026-01-27-18-49-17.png)
+```
+UTILIZATION_FLOOR = 0.20
+惩罚系数 = min(1, boundary_utilization / UTILIZATION_FLOOR)
+最终强度分 = 原强度分 × 惩罚系数
+```
+
+当边界利用率明显偏低时，总分会被进一步压制。
+
+### 结果字段
+
+`ConvergingTriangleResult` 新增字段：
+```python
+boundary_utilization: float = 0.0  # 边界利用率分数
+```
+
+### 效果
+
+- 价格贴近边界（空白少）→ 利用率高 → 强度分高
+- 价格远离边界（空白多）→ 利用率低 → 强度分被惩罚
+- 当边界利用率 < 0.20 时，强度分按比例衰减（空白惩罚）
+- 解决"形状收敛但空白多"的误判问题
+
+# 上/下沿线，有些点没有碰到线的边缘
