名称: MIG and MC — 微缺口与微通道识别

概述:

自动识别价格中的微缺口（Micro Gaps, MIG）与微通道（Micro Channels, MC）。
提供“连续同向微缺口合并（CC MIG）”、强收盘过滤、忽略日内开盘跳空、以及灵活显示与样式控制。
缺口参考线（FPL）会在首次被触及时停止延伸，便于观察“触及/回补”行为。
判定逻辑:

微缺口（MIG）
看涨 MIG: high[2] <= low[0]（启用“零高度 MIG”时为 <=，否则为 <）。
看跌 MIG: low[2] >= high[0]（启用“零高度 MIG”时为 >=，否则为 >）。
绘制内容：以缺口边界价构建盒形区间与一条 FPL 参考线（看涨用绿色、看跌用红色）。
连续 MIG（CC MIG）启用时：同向连续缺口将被合并，绘制“主 FPL”与可选“次 FPL”（次 FPL 为起始价与当前极值的均值），两者在首次被触及时“钉住”并停止延伸。
微通道（MC）
看涨通道：一段连续“低点不破低”的序列，长度 ≥ 最小长度。
看跌通道：一段连续“高点不破高”的序列，长度 ≥ 最小长度。
严格过滤（可选）：要求通道内至少出现一次强收盘（IBS > 69 为强阳，IBS < 31 为强阴）且包含至少一个同向 MIG。
可视化：通道进行中绘制动态趋势线；通道结束后固定最终线段。
主要参数（Inputs）

Micro Gap
Enable Micro Gap Detection: 是否启用 MIG 识别
Lookback Period: 回看范围（默认 200），超出范围的缺口自动清理
Enable Gap Closing: 开启“自动关闭”逻辑（缺口持续状态满足关闭条件时自动移除）
Show ZH MIG: 显示“零高度”缺口（包含等号的判定）
Show CC MIG: 合并连续同向 MIG，并绘制主/次 FPL
Ignore Opening Gaps: 日内忽略开盘跳空
Display
颜色与线型：看涨/看跌缺口颜色、FPL 颜色、线型（实线/虚线/点线）、线宽
Micro Channel
Enable Micro Channel Detection: 启用 MC 识别
Minimum Length: 最小通道长度（默认 3）
Trend Line Width / Opacity: 趋势线宽度与不透明度
Bullish/Bearish Channel Color: 多/空通道颜色
Require Strong Close & Micro Gap: 严格过滤（强收盘+内含 MIG）
使用建议:

任何周期均可用；日内建议开启“Ignore Opening Gaps”以排除日间开盘跳空干扰。
“Lookback Period”平衡画图数量与性能；默认 200 较为稳妥。
CC MIG 适合评估同向推进与层层推进的回补路径；FPL 被触后不再延伸，有助于直观看到“触及/回补”。
说明:

本指标不提供交易建议，仅供学习与研究。
未包含报警条件；如需提醒，可根据 FPL 触及或通道结束逻辑自行添加 alert 条件。

English Description

Name: MIG and MC — Micro Gaps & Micro Channels

Overview:

Detects Micro Gaps (MIG) and Micro Channels (MC) on any timeframe.
Supports merging consecutive same-direction gaps (CC MIG), strict filters for channels, ignoring intraday opening gaps, and rich display controls.
Fair Price Line (FPL) stops extending after first touch, helping visualize “touch/fill” behavior.
Logic:

Micro Gaps (MIG)
Bullish MIG: high[2] <= low[0] (inclusive when “Show ZH MIG” is on; otherwise strict <).
Bearish MIG: low[2] >= high[0] (inclusive when “Show ZH MIG” is on; otherwise strict >).
Visualization: a gap box plus one FPL at the gap boundary (green for bullish, red for bearish).
With CC MIG enabled: merges consecutive same-direction MIGs and draws a primary FPL and an optional secondary FPL (secondary = average of start price and current extreme). Both lines get “pinned” (stop extending) on first touch.
Micro Channels (MC)
Bullish channel: a run of non-decreasing lows, length ≥ minimum.
Bearish channel: a run of non-increasing highs, length ≥ minimum.
Strict filter (optional): requires at least one strong close inside the channel (IBS > 69 for bull, IBS < 31 for bear) and at least one same-direction MIG.
Visualization: dynamic line while active; final segment is fixed once the channel ends.
Key Inputs

Micro Gap
Enable Micro Gap Detection
Lookback Period (default 200): auto-cleans older items
Enable Gap Closing: auto-remove gaps that meet the closing condition
Show ZH MIG: allow zero-height gaps (inclusive inequalities)
Show CC MIG: merge consecutive same-direction MIGs with primary/secondary FPLs
Ignore Opening Gaps: ignore intraday session opens
Display
Colors and styles for gaps and FPLs: line style (solid/dashed/dotted) and width
Micro Channel
Enable Micro Channel Detection
Minimum Length (default 3)
Trend line width and opacity
Bullish/Bearish channel colors
Require Strong Close & Micro Gap (strict filter)

# MIG and MC - Version 8.0 Release Notes

## 📊 Intelligent FPL Drawing with Z-Score Analysis

---

## 🇺🇸 English Version

### 🎯 What's New

**Smart Dual-FPL System**
This major update introduces a statistical approach to FPL (Fill Price Level) drawing. Instead of simply counting consecutive gaps, the indicator now uses **Z-Score analysis** to intelligently determine when a gap is statistically significant enough to warrant drawing two FPLs (boundary + midpoint).

### ✨ Key Features

#### 1. **Z-Score Based Gap Analysis**
- Gaps are now measured against historical data using statistical Z-Score
- Large gaps (Z-Score > threshold) automatically draw 2 FPLs for better precision
- Small gaps draw only 1 FPL to avoid chart clutter
- **Unified logic**: Same intelligent decision-making for both single and consecutive MIGs

#### 2. **New Settings**

**Z-Score for FPL** section in indicator settings:
- `Gap Z-Score Lookback` (default: 20)
Number of historical gaps used to calculate average and standard deviation

- `Gap Z-Score Threshold` (default: 1.05)
Gaps with Z-Score above this threshold will draw 2 FPLs

**Recommended Settings:**
- **Conservative**: Threshold = 1.5 (fewer dual-FPLs, only very large gaps)
- **Balanced**: Threshold = 1.05 (default)
- **Aggressive**: Threshold = 0.5 or 0.8 (more dual-FPLs)

#### 3. **Debug Dashboard** 📈

Six new data window indicators help you understand the decision-making:

| Indicator | Description |
|-----------|-------------|
| **History Size** | Number of gaps in historical database (builds up to 20) |
| **Gap Avg** | Average gap size over lookback period |
| **Gap StdDev** | Standard deviation of historical gaps |
| **Last Gap Size** | Size of most recent gap (in price points) |
| **Last Gap Z-Score** | Z-Score of most recent gap ⭐ |
| **Threshold** | Current threshold setting (1.05) |

**How to use:** Open the Data Window (right panel) and hover over a gap bar to see these values.

### 🔧 Technical Improvements

#### Gap Size Calculation
- **Fixed**: Bullish gaps now correctly calculate as `currentLow - previousHigh`
- **Fixed**: Bearish gaps now correctly calculate as `previousLow - currentHigh`
- All gap sizes are now positive values

#### Consecutive MIG Logic
- **Fixed**: Continuous gaps now measure total sequence size, not individual bar gaps
- **Enhanced**: Z-Score updates dynamically as sequences extend
- **Optimized**: Historical data only updated at sequence start to prevent pollution

### 🎨 Usage Tips

1. **For volatile markets**: Lower the threshold to 0.5-0.8 to see more dual-FPLs
2. **For ranging markets**: Keep default 1.05 or increase to 1.5
3. **Testing**: Disable "Show CC MIG" to see debug data for individual gaps
4. **Best practice**: Wait for bar confirmation before analyzing debug values

### 📈 Why Z-Score?

Traditional methods treated all gaps equally. The Z-Score approach:
- ✅ Adapts to market volatility automatically
- ✅ Identifies truly anomalous gaps statistically
- ✅ Reduces noise in low-volatility periods
- ✅ Provides objective, data-driven FPL decisions

### 🐛 Bug Fixes

- Fixed negative gap size calculations for bullish MIGs
- Fixed Z-Score calculation for consecutive gap sequences
- Fixed historical array updating timing issues
- Improved debug variable updates for real-time visibility

## 🇨🇳 中文版本

### 🎯 更新内容

**智能双FPL系统**
此次重大更新引入了统计学方法来绘制FPL（填充价格水平线）。指标不再简单地计算连续缺口数量，而是使用**Z-Score分析**来智能判断缺口是否具有统计显著性，从而决定是否绘制两条FPL（边界+中点）。

### ✨ 核心功能

#### 1. **基于Z-Score的缺口分析**
- 使用历史数据的Z-Score统计方法衡量缺口大小
- 大缺口（Z-Score > 阈值）自动绘制2条FPL，提供更精细的价格参考
- 小缺口只绘制1条FPL，避免图表混乱
- **统一逻辑**：单个MIG和连续MIG使用相同的智能判断标准

#### 2. **新增设置参数**

在指标设置中新增**Z-Score for FPL**部分：
- `Gap Z-Score Lookback`（默认：20）
用于计算均值和标准差的历史缺口数量

- `Gap Z-Score Threshold`（默认：1.05）
Z-Score超过此阈值的缺口将绘制2条FPL

**推荐设置：**
- **保守型**：阈值 = 1.5（只对非常大的缺口绘制双FPL）
- **平衡型**：阈值 = 1.05（默认值）
- **激进型**：阈值 = 0.5 或 0.8（更多双FPL）

#### 3. **调试仪表板** 📈

6个新增数据窗口指标帮助您理解决策逻辑：

| 指标名称 | 说明 |
|---------|------|
| **History Size** | 历史数据库中的缺口数量（逐渐增长至20） |
| **Gap Avg** | 回看期内的平均缺口大小 |
| **Gap StdDev** | 历史缺口的标准差 |
| **Last Gap Size** | 最近缺口的大小（价格点数） |
| **Last Gap Z-Score** | 最近缺口的Z-Score值 ⭐ |
| **Threshold** | 当前阈值设置（1.05） |

**使用方法：** 打开数据窗口（右侧面板），将鼠标悬停在有缺口的K线上查看这些数值。

### 🔧 技术改进

#### 缺口大小计算
- **修复**：看涨缺口现在正确计算为 `当前低点 - 之前高点`
- **修复**：看跌缺口现在正确计算为 `之前低点 - 当前高点`
- 所有缺口大小现在均为正值

#### 连续MIG逻辑
- **修复**：连续缺口现在测量整个序列的总大小，而非单个K线的缺口
- **增强**：Z-Score随着序列延伸动态更新
- **优化**：历史数据仅在序列开始时更新，防止数据污染

### 🎨 使用技巧

1. **高波动市场**：降低阈值至0.5-0.8以看到更多双FPL
2. **震荡市场**：保持默认1.05或提高至1.5
3. **测试**：关闭"Show CC MIG"选项可查看单个缺口的调试数据
4. **最佳实践**：等待K线确认后再分析调试数值

### 📈 为什么使用Z-Score？

传统方法对所有缺口一视同仁。Z-Score方法的优势：
- ✅ 自动适应市场波动性
- ✅ 统计学识别真正的异常缺口
- ✅ 在低波动期减少噪音
- ✅ 提供客观的、数据驱动的FPL决策

### 🐛 Bug修复

- 修复了看涨MIG的负值缺口大小计算错误
- 修复了连续缺口序列的Z-Score计算逻辑
- 修复了历史数组更新时机问题
- 改进了调试变量的实时更新可见性
