able bigtrades dom + liquidity sweep

This Pine Script is a sophisticated **Order Flow and Liquidity analysis tool** designed for TradingView. It combines volume analysis, multi-exchange data, and price action to identify where institutional "whales" are entering the market.

Below is a detailed guide on how to interpret and use the **BigTrades DOM** indicator.

---

## 1. Core Concept: Big Trades Detection

Instead of looking at raw volume, this indicator uses **Z-Scores** (Standard Deviations). It compares current volume to the average of the last 30 bars (customizable).

* **Tier 1 (Small Circles):** Significant volume, slightly above average.
* **Tier 2 (Medium Circles):** High volume ( by default). These often act as local support/resistance.
* **Tier 3 (Large Circles):** Extreme volume. These represent institutional "Big Trades" that usually lead to trend reversals or major continuations.

---

## 2. Initiative (INIT) vs. Absorbed (ABS)

This is a powerful feature located in the **Confirmation** settings. It looks at what happens *after* a Tier 3 big trade occurs:

* **Initiative (Purple Circle `●`):** High volume occurs, and price **moves strongly** in that direction within bars. This confirms aggressive "Initiative" buying or selling.
* **Absorbed (Yellow Cross `✕`):** High volume occurs, but price **fails to move**. This indicates "Absorption"—where a large limit order (passive seller) is soaking up all the aggressive market buys, often leading to a reversal.

---

## 3. Liquidity Sweep Detection

The script tracks "Pivots" (old highs and lows) and watches for **Stop Runs**.

* **Bullish Sweep (LTL-SWEEP):** Price dips below a previous Low (Liquidity) but immediately closes back above it, usually accompanied by a Big Trade. This is a classic "Stop Hunt" before a move up.
* **Bearish Sweep (LTH-SWEEP):** Price spikes above a previous High but closes below it. This indicates "trapped longs" and potential downside.
* **Visuals:** The script draws a **Dotted Box** and a **Horizontal Line** to mark the swept liquidity zone.

## 4. The Mini DOM & Volume Profile

On the right side of your chart, you will see a real-time table:

* **Profile:** A visual histogram of volume distributed at specific price levels.
* **Bid/Ask:** Shows the estimated volume of sellers (Bid) and buyers (Ask) at those specific levels.
* **Delta (Δ):** The net difference. Green means more aggressive buyers; Red means more aggressive sellers.
* **Current Price:** Highlighted in Green to help you see where the "Value" is currently sitting.

## 5. Multi-Exchange Aggregation (Crypto Only)

If you are trading a crypto pair (e.g., BTCUSD), the script can fetch volume data from **Binance, Bybit, OKX, Coinbase, and Kraken** simultaneously.

> **Why it matters:** It gives you a "Global" view of volume. If you see a Big Trade on your chart, but the Multi-Exchange data shows high volume across all 5 exchanges, the signal is much more reliable.

## 6. How to Trade with this Indicator

### **Strategy A: The Liquidity Reversal**

1. Look for a **Liquidity Sweep** (LTL-SWEEP).
2. Wait for a **Big Trade (Tier 2 or 3)** to appear at the bottom of the sweep.
3. **Entry:** Long when the bar closes back above the sweep level.
4. **Target:** The opposite Liquidity High.

### **Strategy B: Following Initiative**

1. Wait for an **INIT (Purple Circle)** signal.
2. This confirms that the "Big Trade" has successfully pushed the market.
3. **Entry:** Enter in the direction of the INIT signal on the next pullback.

### **Strategy C: Fading Absorption**

1. Price reaches a resistance level.
2. An **ABS (Yellow Cross)** appears.
3. This means buyers are exhausted and being "absorbed" by a large seller.
4. **Entry:** Short on the break of the Absorption candle's low.

## 7. Recommended Settings

* **Sensitivity (Sigma):** Set to `2.5` for volatile markets (Crypto) or `2.0` for slower markets (Forex/Stocks).
* **Normalize by ATR:** Keep this **ON**. it ensures that "Big Trades" are calculated relative to current market volatility.
* **Require Big Trade (Sweep):** Keep this **ON** to filter out "fake" sweeps that don't have institutional backing.
