Vector Trinity III: Flow [CVD]

**1. Introduction: The Truth Serum**
This indicator is **Part 3** of the "Vector Trinity" trading system. It is the final validator in the decision-making process.
While Part I defines the *Structure* and Part II identifies the *Impulse*, **Part III (Flow)** answers the most critical question in trading: **"Is there real money behind this move?"**
It represents the **Energy Dimension**, analyzing the Cumulative Volume Delta (CVD) to spot true breakouts and expose traps.

* **I: Structure:** Spatial boundaries.
* **II: Impulse:** Momentum timing.
* **III: Flow:** **Capital validation & Divergence detection (Current Indicator).**

**2. Core Logic: CVD Estimation**
True "Delta" requires tick-by-tick data, which is often unavailable or premium-locked. **Vector Trinity III** uses a sophisticated **Intrabar Position Estimation** algorithm to mathematically approximate buying vs. selling pressure:
* **The Math:** It analyzes where the Close sits relative to the High and Low of the candle.
* Close near High = Dominant Aggressive Buying.
* Close near Low = Dominant Aggressive Selling.
* **The CVD:** It accumulates these delta values over time to create a continuous "Flow" line. This reveals the long-term intent of smart money.

**3. The Trend Line & Divergence**
The indicator features a **Grey Trend Line** (EMA of CVD) which serves as the baseline for "Net Flow."
* **Teal Zone (Above Trend):** Net Inflow. Capital is aggressively entering the market, supporting the price.
* **Maroon Zone (Below Trend):** Net Outflow. Capital is leaving the market, suggesting weakness.

**4. The "Trap" Detector (Divergence)**
The primary superpower of this indicator is spotting **Divergences**:
* **The Bull Trap (Fakeout):** Price makes a Higher High, but CVD makes a Lower High (or trends down).
* *Meaning:* The price is rising due to a lack of liquidity, not aggressive buying. **Smart money is selling into the rally.**
* **The Bear Trap (Shakeout):** Price makes a Lower Low, but CVD makes a Higher Low.
* *Meaning:* Smart money is absorbing the selling pressure (buying the dip).

**5. How to Use**
* **The "Trinity" Confirmation:** Before taking a trade based on Part I (Structure) and Part II (Impulse), look at Part III.
* **For a Long Setup:**
1. Price breaks the Structure (Part I).
2. Momentum fires Green/Cyan (Part II).
3. **Flow (Part III) MUST be Teal and rising.**
* **The Veto Rule:** If Price breaks up, but Flow is Maroon/Falling, **CANCEL the trade**. It is likely a trap.

**Settings:**
* **Trend Length:** 20 (Standard trend baseline to determine Net Inflow/Outflow).

### **中文说明**

**1. 简介：市场的“测谎仪”**
本指标是“矢量三位一体”交易系统的 **第三部分**。它是决策过程中最后的验证者。
第一部分 (Structure) 定义了结构，第二部分 (Impulse) 识别了脉冲，而 **第三部分 (Flow)** 则回答了交易中最关键的问题：**“这波行情背后有真钱吗？”**
它代表了系统的 **能量维度**，通过分析累积成交量 Delta (CVD) 来识别真正的突破并揭露市场陷阱。

* **I: Structure 结构：** 空间边界。
* **II: Impulse 脉冲：** 动能时机。
* **III: Flow 流向：** **资金验证与背离侦测（本指标）。**

**2. 核心逻辑：CVD 估算算法**
真正的“Delta”数据通常需要逐笔成交数据 (Tick Data)，这往往需要付费数据源。**Vector Trinity III** 使用了一套精密的 **K线内相对位置估算 (Intrabar Position Estimation)** 算法，在数学上逼近真实的买卖压力：
* **算法原理：** 它分析收盘价在 K 线最高价和最低价之间的相对位置。
* 收盘接近最高价 = 主动买入主导。
* 收盘接近最低价 = 主动卖出主导。
* **CVD (累积值)：** 它将这些 Delta 值随时间累积，形成一条连续的“资金流向”线。这揭示了主力资金的长期意图。

**3. 趋势线与背离**
指标包含一条 **灰色趋势线** (CVD 的均线)，作为“净流量”的基准。
* **青色区域 (趋势线上方)：** 净流入。资金正在积极入场，支撑价格上涨。
* **深红区域 (趋势线下方)：** 净流出。资金正在撤离市场，暗示行情虚弱。

**4. “陷阱”侦测器 (背离)**
本指标的核心超能力是识别 **背离 (Divergence)**：
* **多头陷阱 (诱多/假突破)：** 价格创出新高，但 CVD 却创出新低（或趋势向下）。
* *含义：* 价格上涨是因为缺乏流动性（空涨），而不是因为有主动买盘。**主力资金正在借反弹出货。**
* **空头陷阱 (诱空/洗盘)：** 价格创出新低，但 CVD 却在抬高。
* *含义：* 主力资金正在吸收抛压（在此位置吸筹）。

**5. 使用方法**
* **“三位一体”共振验证：** 在根据第一部分 (结构) 和第二部分 (脉冲) 开单之前，必须查看第三部分。
* **做多设置：**
1. 价格突破结构 (Part I)。
2. 动能点火变绿/青色 (Part II)。
3. **资金流 (Part III) 必须呈现青色且向上攀升。**
* **一票否决权：** 如果价格向上突破，但资金流是深红色/下降的，**立即取消交易**。这极大概率是一个陷阱。

**参数设置：**
* **Trend Length (趋势周期)：** 20 (用于确定净流入/流出的标准基准线)。
