Golden Ratio Levels: Static Range Anchor

核心功能
本指标基于指定历史区间（可偏移）的最高点和最低点，在图表右侧绘制静态的黄金分割支撑/阻力位。所有数值仅在最后一根K线确定，永不重绘，信号稳定可靠。

特点与优势

✅ 不重绘：只在图表最新K线计算一次，避免未来函数影响，适合交易决策。
✅ 偏移周期：可跳过最近若干K线，剔除未完成K线或短期噪声，使区间更具代表性。
✅ 视觉清晰：不同颜色和线型区分各分割位（23.6%、38.2%、50%、61.8%、80.9%），右侧标签显示百分比和精确价格。
✅ 起点修正：垂直线和“起点”标签精确对齐计算区间的第一根K线，无视觉偏移。
✅ 内存优化：自动清理旧图形，保持图表简洁。

参数说明

统计周期：用于寻找高点和低点的K线数量。
偏移周期：将计算窗口向后移动的K线数（从当前K线往前推）。
显示比例标签：控制右侧百分比标签的显隐。

适用场景

识别趋势中的回调支撑（上涨后回调至38.2%、50%、61.8%）
判断反弹阻力（下跌后反弹至上述位置）
结合K线形态、成交量或其他指标提高胜率

注意事项

本指标为静态工具，只在最新K线显示当前周期的分割线，切换K线或滚动历史时旧线不保留。
黄金分割位是概率性位置，需配合市场确认信号使用。

Core Function
This indicator calculates static Fibonacci retracement levels based on the highest and lowest points of a user-defined historical range (with an optional offset). Values are anchored only on the last bar, ensuring no repainting for reliable signals.

Features & Benefits

✅ No Repaint: Calculated once on the latest bar, eliminating future data bias.
✅ Offset Parameter: Skip recent bars to avoid incomplete candles or short-term noise.
✅ Clear Visualization: Distinct colors and line styles for each level (23.6%, 38.2%, 50%, 61.8%, 80.9%), with right-side labels showing percentages and exact prices.
✅ Accurate Start Point: The vertical dotted line and "Anchor Point" label exactly mark the first bar of the calculation window.
✅ Memory Efficient: Old drawings are automatically deleted to keep charts tidy.

Input Parameters

Lookback Period: Number of bars to search for high/low values.
Offset Bars: Shift the calculation window backward from the current bar.
Display Labels: Toggle percentage labels on/off.

Use Cases

Identify pullback supports in uptrends (38.2%, 50%, 61.8%)
Spot rebound resistances in downtrends
Combine with candlestick patterns, volume, or other indicators for higher accuracy

Note

This is a static tool; levels are shown only for the current period on the last bar. Historical periods are not retained when scrolling.
Fibonacci levels are probabilistic—always confirm with market context.
