Elder AutoEnvelope 1m/5mOverview
This script is an advanced implementation of Dr. Alexander Elder’s AutoEnvelope, specifically optimized for 1-minute (1m) and 5-minute (5m) low-timeframe trading.
The logic treats the market as a "manic-depressive" entity:
Center Line (26 EMA): Represents the fair value consensus.
Fast Line (13 EMA): Captures short-term price momentum.
Envelopes (Bands): Represent the limits of price "sanity." Under normal conditions, 95% of price action should remain within these bands.
Key Features
Powered by Pine Script V6: Built on the latest engine for maximum precision and performance.
Real-time Coverage Tracker: A dashboard in the top-right corner displays the percentage of price bars contained within the bands over the lookback period. The goal is to adjust the Multiplier until coverage is ~95%.
Dual Smoothing: To combat high-frequency noise on 1m/5m charts, this script applies a secondary smoothing layer to the channel width, preventing the "jagged" lines found in standard indicators.
Recommended Settings
Lookback: Defaulted to 300. On a 1m chart, this represents 5 hours of data, providing a much more robust "normal" range than the standard 100-period setting.
Multiplier: Usually ranges between 2.0 and 3.5 depending on the asset's volatility. Tune this until the Coverage Panel shows ~95%.
SmoothLen: Defaulted to 20. Increase this value for even smoother, more "parallel" bands during high-noise sessions.
Practical Trading Advice
Take Profit Zones: In an uptrend, treat the Upper Band as a primary target. When price pierces the band and closes back inside, it’s often the climax of the move.
Mean Reversion: When price touches the Lower Band while significantly stretched away from the yellow Center Line, look for a bounce back to the value area, especially if the Purple Fast Line begins to flatten.
Trend Filtering:
Price above Fast Line (Purple) + Upward slope: Bullish bias. Only look for Longs or Profit Taking.
Price below Fast Line (Purple) + Downward slope: Bearish bias. Only look for Shorts or Covering.
Asset Calibration: When switching assets (e.g., Gold to BTC), always fine-tune the Multiplier. The bands are only statistically valid when the Coverage Panel stays between 94% and 96%.
指标简介
本脚本是基于亚历山大·爱尔德博士(Dr. Alexander Elder)著名的“自动包络线”(AutoEnvelope)理论开发的进阶版本,特别针对 1分钟(1m)和 5分钟(5m) 等短周期高频交易进行了优化。
该指标的核心逻辑是将市场视为一个“躁郁症患者”:
中心线 (26 EMA):代表市场的平均价值认同。
快线 (13 EMA):代表短期价格动能。
包络线 (Bands):代表价格波动的极端边界(95% 的价格应运行在通道内)。
核心功能
V6 引擎驱动:采用最新的 Pine Script V6 编写,计算更精准,内存占用更低。
实时覆盖率统计:右上角实时显示过去 300 根 K 线中有多少比例落在通道内。目标是手动调整倍数(Multiplier)使该数值维持在 95% 左右。
双重平滑处理:针对短线噪音,对通道宽度进行了二次平滑,避免了传统指标在 1 分钟图上常见的“锯齿状”变形。
参数设置建议
Lookback (回溯周期):默认 300。在 1m 图上代表过去 5 小时,能提供比默认 100 周期更稳定的边界。
Multiplier (偏离倍数):根据不同品种调整(通常在 2.0 - 3.5)。请观察右上角面板,当覆盖率接近 95% 时,该倍数最为准确。
SmoothLen (平滑系数):默认 20。如果觉得轨道太乱,可调高此值。
实际交易建议
波段止盈点:在上升趋势中,当价格刺破上轨且 K 线实体收回上轨下方时,是绝佳的多头平仓位。
均值回归:当价格偏离中心线触碰下轨,且快线(紫色)开始走平时,预示即将反弹回中心线。
趋势过滤:
价格在快线(紫色)上方且快线斜率向上:只做多或平多,不逆势抄顶。
价格在快线(紫色)下方且快线斜率向下:只做空或平空。
覆盖率校准:切换交易品种(如从黄金切换到比特币)后,务必微调 Multiplier,确保覆盖率处于 94%-96% 之间,此时的边界才具有统计学意义。
