Ang Multi EMA with labels (Any timeframe)功能
这个脚本是一个多周期指数移动平均线（EMA）指标，专为 TradingView 设计，可在任意图表周期上同时显示多达 8 条不同周期和时间框架的 EMA 线，并在图表右侧自动生成带有价格标签的标注。它的核心功能包括：
支持自定义每条 EMA 的周期、时间框架（如 5 分钟、1 小时、日线等）和颜色。
当未指定时间框架时，直接计算当前图表周期的 EMA，与原生 EMA 指标完全对齐。
当指定跨周期时，调用对应时间框架的 EMA 数据，并保持与原生指标一致的计算逻辑。
自动生成清晰的标签，显示 EMA 的周期、时间框架和当前价格，便于快速识别。
Function:
This script is a multi-timeframe Exponential Moving Average (EMA) indicator designed for TradingView. It can display up to 8 EMA lines with different periods and timeframes on any chart, and automatically generate labeled annotations on the right side of the chart showing the current price. Its core features include:
Customizable period, timeframe (e.g., 5min, 1H, daily), and color for each EMA line.
When no timeframe is specified, it calculates the EMA for the current chart period, perfectly aligning with the native EMA indicator.
When a cross-timeframe is specified, it fetches EMA data from the corresponding timeframe while maintaining calculation logic consistent with native indicators.
Automatically generates clear labels showing the EMA period, timeframe, and current price for quick identification.
优势
精准对齐：通过统一计算逻辑，确保在当前周期（如 5 分钟）上的 EMA 与 TradingView 原生 EMA 指标完全一致，消除数值偏差。
多周期灵活配置：支持同时监控多达 8 条 EMA，可自由组合不同时间框架（如 5 分钟 EMA20 + 1 小时 EMA50），满足多周期共振分析需求。
直观可视化：自动生成的右侧标签清晰标注每条 EMA 的关键信息，无需频繁切换指标设置或查看数据窗口。
无未来函数风险：默认使用实时数据计算，避免了因使用未来数据导致的指标重绘问题，信号更可靠。
高度可定制：用户可自由调整 EMA 的颜色、线宽、标签距离等参数，打造符合个人交易风格的界面。
Pros
Precise Alignment: By unifying the calculation logic, it ensures that the EMA on the current timeframe (e.g., 5min) is perfectly aligned with TradingView's native EMA indicator, eliminating numerical discrepancies.
Flexible Multi-Timeframe Configuration: Supports monitoring up to 8 EMAs simultaneously, allowing free combinations of different timeframes (e.g., 5min EMA20 + 1H EMA50) to meet multi-timeframe confluence analysis needs.
Intuitive Visualization: Automatically generated labels on the right clearly display key information for each EMA, eliminating the need to frequently switch indicator settings or check data windows.
No Repainting Risk: Uses real-time data by default, avoiding repainting issues caused by lookahead data, resulting in more reliable signals.
Highly Customizable: Users can freely adjust parameters such as EMA color, line width, and label distance to create an interface tailored to their personal trading style.
