核心逻辑
该指标是一个**趋势跟踪系统**，主要通过画线来识别股价的支撑位和压力位，并判断趋势的转折点。具体原理： 1. **AB线（黄色）**：连接短期高点形成的下降趋势线，作为短期压力参考 2. **CD线（浅蓝色）**：连接60日周期内的高低点形成的趋势线，作为中长期趋势参考 3. **蓝色/红色粗线**：分别标记长期（8日周期）和短期（3日周期）的高低点 4. **粉色/黄色斜线**：辅助判断趋势的阶段性高点 5. **压力/支撑线**：通过VAR1111-VAR4444计算出的关键价位，用彩色横线标注
买卖信号
- **买入信号（B）**：当股价从下往上突破AB线时，显示"买入"标记 - **卖出信号（注）**：当CD线从下往上突破股价时，显示"卖出"标记
用法
1. **看趋势方向**：观察CD线的倾斜方向，向上则多头趋势，向下则空头趋势 2. **买入时机**：股价上穿AB线时考虑买入，AB线可作为止损参考 3. **卖出时机**：当CD线被上穿时考虑卖出或减仓 4. **支撑压力**：粉色横线为压力位，蓝色横线为支撑位
