ICU AVG Line[MIT]

ICU AVG Line [MIT]
Overlay indicator (overlay=true), drawn directly on the price chart
Main Functionality:
Plots a dynamic line called “ICU Prediction Line” based on confirmed historical bars, representing a special form of “predicted central level”.
The line changes color in real-time based on the current price’s position relative to the ICU line:
Price above ICU → Green (bullish bias)
Price below ICU → Red (bearish bias)

1. Uses only closed bar data for calculation, ensuring the line remains stable during the current open bar (no repainting or jumping).
   
2. Displays a small label on the right side of the latest bar showing the current ICU value (“ICU: xxx.xx”), with color matching the line.
   
3. Includes commented alert conditions (ready to enable):
   
4. Price crosses above ICU → Potential buy signal
   
5. Price crosses below ICU → Potential sell/exit signal
   

Visual Elements:

1. Green/Red dynamic line: ICU Prediction Line (main line), width 2, broken line style, color flips based on price position.
   
2. Small label: Shows current ICU value on the right of the latest bar, colored to match the line.
   
3. Maximum 500 line segments preserved (max_lines_count=500) for smooth long-term chart performance.
   

Typical Usage Scenarios:

1. Trend Following: Price consistently stays above the ICU line and the line is sloping upward → Strong bullish trend, consider holding long or adding.
   
2. Dynamic Support/Resistance: ICU line often acts as moving support/resistance; multiple tests without breaking → Strong level.
   
3. Crossover Signals: Price crosses above ICU from below (color turns green) → Potential bullish entry; crosses below (color turns red) → Potential bearish or exit signal.
   
4. Range Filter: Price repeatedly crosses ICU with the line flattening → Choppy market, better to stay aside or scalp.
   

Parameter Description:
window: Default 5, controls smoothness and responsiveness of the ICU line. Larger values = smoother (better for swing/mid-term); smaller values = more sensitive (better for intraday).
主要功能：

1. 在价格图表上绘制一条名为“ICU 预测线”的动态曲线，该曲线基于历史已确认K线数据计算得到，代表一种特殊的“预测中心位置”。
   
2. 曲线颜色会根据当前价格与ICU线的相对位置实时变化：
   
3. 价格在ICU线上方 → 绿色（偏多头）
   
4. 价格在ICU线下方 → 红色（偏空头）
   
5. 使用历史闭合数据计算，确保指标在未闭合K线期间保持稳定（不跳动），避免未来函数干扰。
   
6. 在图表最后一根K线右侧显示实时数值标签（“ICU: xxx.xx”），方便快速查看预测值。
   
7. 支持设置警报条件（已注释，可自行开启）：
   
8. 价格上穿ICU线 → 潜在买入信号
   
9. 价格下穿ICU线 → 潜在卖出信号
   

图表呈现：

1. 绿色/红色动态折线：ICU预测线（主线），宽度2，断线显示（style=plot.style_linebr），颜色随价格位置变化。
   
2. 小标签：在最新K线右侧显示当前ICU数值，颜色与主线同步。
   
3. 线条最多保留500段（max_lines_count=500），保证长期图表不卡顿。
   

使用场景建议：

1. 趋势跟随：价格持续运行在ICU线上方且ICU线向上倾斜 → 强势多头，可考虑持多或加仓。
   
2. 支撑/阻力参考：ICU线常作为动态支撑或阻力，价格多次测试不破 → 强支撑位。
   
3. 穿越信号：价格从下方上穿ICU线（绿色变色）→ 多头启动信号；从上方下穿（红色变色）→ 空头启动或离场信号。
   
4. 震荡过滤：价格在ICU线附近反复穿越且ICU线走平 → 震荡行情，适合观望或短线高抛低吸。
   

参数说明：
window（窗口长度）：默认5，控制ICU线的平滑度和反应速度。数值越大越平滑，适合中长线；数值越小越敏感，适合短线。
