指标名称：Gann_S9[color=rgba(0, 0, 0, 0.9)]
版本：MT4 ver. 2.01
[size=16.002px]Gann_S9是基于改进型ZigZag的趋势分析工具，通过自动绘制支撑/阻力线和甘氏角度线，帮助交易者识别潜在的趋势转折点。
[size=16.002px]指标包含以下主要功能： 智能绘制ZigZag折线 自动生成支撑/阻力位 绘制甘氏角度线 标记关键价格水平
1. 核心功能ZigZag折线：自动标记显著的高低点 支撑/阻力线： 蓝色：支撑位 红色：阻力位 角度线：以基准点为中心展开的扇形线
2. 参数调整建议[td]参数组 | 推荐值 | 效果说明 | ZigZag | Depth=21, Deviation=5 | 平衡灵敏度和稳定性 | 角度线 | angle=22.5°, kol_lev=8 | 显示8条不同角度线 | 样式 | Width=2, Style=0 | 使用粗实线提高可视性 |
3. 交易信号解读趋势确认：当价格突破多条角度线时 反转信号：ZigZag出现新折点 + 角度线群集 支撑阻力：水平线密集区为关键价位
