Vector Trinity I: Structure [VWAP-DBB]

vor 5 Stunden

This indicator is **Part 1** of the "Vector Trinity" trading system—a comprehensive, data-driven framework designed to analyze market behavior through three distinct physical dimensions:
* **I: Structure (Space):** Defines the battlefield and volatility boundaries (Current Indicator).
* **II: Impulse (Time):** Identifies momentum ignition and energy release.
* **III: Flow (Energy):** Validates the move via volume and capital flow.

**2. Core Logic: Why Rolling VWAP?**
Most standard Bollinger Bands use a Simple Moving Average (SMA) as the centerline. The flaw in SMA is that it treats every candle equally, regardless of trading activity.
**Vector Trinity I** replaces the SMA with a **Rolling VWAP (Volume-Weighted Average Price)** over a rolling window (default 20).
* **Data Logic:** Price combined with Volume represents the true "cost basis" of the market.
* **Behavior:** The centerline becomes "sticky" during high-volume nodes and moves faster when real capital enters. It represents the *True Mean* of the market structure.

**3. The Dual-Band "Highway" Structure**
Instead of a single channel, this system utilizes a Double Bollinger Band (DBB) architecture based on Standard Deviations (StdDev) from the VWAP:
* **The Noise Zone (Basis to 1.0 StdDev):** The empty space in the middle. Price action here is often choppy and directionless.
* **The Acceleration Zone (1.0 to 2.0 StdDev):** The filled "Cloud." When candles close and stay within this zone, it indicates a strong trend (The Highway).
* **The Reversion Zone (> 2.0 StdDev):** Price is statistically extended and may revert to the mean.

**4. Volatility Squeeze Detection**
The indicator integrates a mechanical "Squeeze" detection based on the relationship between the Bollinger Bands (Variance) and Keltner Channels (ATR).
* **Squeeze ON (Orange Cloud & Dots):** Daily variance is at extreme lows. Energy is compressing. Do not trade direction; prepare for a breakout.
* **Squeeze OFF (Grey Cloud):** Expansion phase. Volatility is returning to the market.

**5. How to Use**
* **Step 1:** Observe the **Purple Line (VWAP)**. Its slope dictates the dominant trend structure.
* **Step 2:** Look for **Orange Zones**. This indicates a "Squeeze." Wait for the cloud to turn Grey.
* **Step 3:** Trade the breakout when price closes inside the "Acceleration Zone" (between the inner and outer bands) accompanied by Volume.

**Settings:**
* **Rolling Length:** 20 (Standard for swing/day trading).
* **Inner/Outer Bands:** 1.0 / 2.0 (The standard trend definition).
* **Squeeze Sensitivity:** 1.5 (Standard KC Multiplier).

### **中文说明**

**1. 简介：矢量三位一体系统 (Vector Trinity)**
本指标是“矢量三位一体”交易系统的 **第一部分**。这是一套基于数据逻辑的综合分析框架，旨在通过三个物理维度解构市场行为：
* **I: Structure 结构 (空间)：** 定义价格运行的战场边界与波动率结构（本指标）。
* **II: Impulse 脉冲 (时间)：** 识别动能的点火与能量释放。
* **III: Flow 流向 (能量)：** 通过成交量与资金流验证突破的真伪。

**2. 核心逻辑：为什么要用 Rolling VWAP？**
传统的布林带使用简单移动平均线 (SMA) 作为中轨。SMA 的缺陷在于它平等地对待每一根 K 线，而忽略了成交量的权重。
**Vector Trinity I** 使用 **Rolling VWAP (滚动成交量加权平均价)** 替代了 SMA。
* **数据逻辑：** 只有结合了成交量的价格，才代表市场真实的“平均持仓成本”。
* **表现特征：** 在放量交易区，中轨会表现出更强的支撑/阻力特性；在缩量区则表现平滑。它代表了市场结构的*真实均值*。

**3. 双通道“高速公路”结构**
本系统不使用单条轨道，而是基于 VWAP 的标准差 (StdDev) 构建了双重布林带 (DBB) 架构：
* **噪音区 (中轨 到 1.0 标准差)：** 中间的空白区域。在此区域内的价格通常是无方向的震荡。
* **加速区 (1.0 到 2.0 标准差)：** 填充颜色的“云带”。当 K 线收盘并运行于此区域时，代表趋势确立，价格进入了“高速公路”。
* **回归区 (> 2.0 标准差)：** 价格在统计学上过热，可能面临均值回归。

**4. 波动率挤压监测 (Squeeze)**
指标内置了基于布林带（方差）与肯特纳通道（ATR）对比的机械化“挤压”监测。
* **挤压状态 (橙色云带 & 底部圆点)：** 每日方差处于极低值 (Variance at extreme lows)。市场正在积蓄能量。此时不应猜测方向，而应等待爆发。
* **扩张状态 (灰色云带)：** 挤压结束，波动率回归，趋势展开。

**5. 使用方法**
* **第一步：** 观察 **紫色中轨 (VWAP)**。它的倾斜方向决定了主要的结构趋势。
* **第二步：** 寻找 **橙色区域**。这代表“挤压”正在发生。耐心等待云带变回灰色。
* **第三步：** 当价格突破并收盘在“加速区”（内轨与外轨之间）时，配合成交量介入交易。

**参数设置：**
* **Rolling Length (周期)：** 20 (波段/日内交易的标准设置)。
* **Inner/Outer Bands (内外轨)：** 1.0 / 2.0 (经典的趋势定义范围)。
* **Squeeze Sensitivity (敏感度)：** 1.5 (标准肯特纳通道倍数)。
