Support & Resistance Detector [PRO]

Professional Support & Resistance Detector [PRO] 🟠

Executive Summary 🟠

The **Professional Support & Resistance Detector [PRO]** is an institutional-grade technical analysis instrument built for precision traders. It automates the complex task of identifying significant market structure by detecting valid Swing Highs (Resistance) and Swing Lows (Support) using a customizable dynamic lookback algorithm. Unlike basic indicators that clutter the chart with irrelevant lines, this tool employs smart filtration and FIFO (First-In, First-Out) logic to present only the most actionable price levels.

Whether you are a scalper needing real-time feedback or a swing trader looking for confirmed structural levels, this indicator adapts to your workflow with "Confirmed Only" and "Realtime" calculation modes.

Why Standard Indicators Fail 🟠

Most Support & Resistance indicators suffer from two major problems:
1. **Noise**: They identify too many insignificant levels, making the chart unreadable.
2. **Rigidity**: They fail to account for "Role Reversal" (where old Resistance becomes new Support).

The Solution: Advanced Feature Set 🟠

This script addresses these issues with a suite of advanced features designed for the modern market environment:

1. **Dynamic Algorithmic Detection**:
* The core engine uses a user-defined `Left` and `Right` bar lookback system. This allows you to differentiate between "Major" structural pivots (high lookback) and "Minor" intraday levels (low lookback).
* **Zone Visualization**: Prices rarely turn at an exact micro-level. The indicator draws a transparent "Zone" around the key level to visualize the area of liquidity, helping you avoid premature entries during wick tests.

2. **Smart Breakout Logic (The "Brain" of the Indicator)**:
* **History Mode (Faded)**: When a level is broken, it doesn't just vanish. It stays on the chart but fades out. This is critical for backtesting to see how price reacted to past levels.
* **Role Reversal (Flip) Mode**: This is for active trading. When price breaks Resistance, the line automatically flips color to Support (and vice versa). This allows you to trade the "Break & Retest" strategy effortlessly.

3. **Active Chart Management**:
* Markets evolve. Old levels become irrelevant. The built-in **FIFO Memory System** ensures that you never have more than your specified limit (e.g., 25 lines) on the chart. As new structure forms, the oldest irrelevant data is recycled, keeping your workspace pristine.

4. **Multi-Mode Calculation Engine**:
* **Confirmed Only (Default)**: The professional standard. Levels are only drawn/updated when the candle closes. This guarantees zero repainting and reliable signals.
* **Realtime (Tick-by-Tick)**: Designed for aggressive scalpers who need to see potential pivots forming before the candle closes.

Comprehensive Settings & Customization 🟠

Every aspect of the indicator is customizable to fit your trading style.

Logic & Calculation 🟠
* **Max Active Lines**: Set the buffer size for active levels. Recommended: 20-30 for clean analysis.
* **Line Extension**: Choose "Right" (standard), "Both" (chart-wide context), or "Segment Only" (local structure).

Pivot Identification 🟠
* **Lookback Left/Right**: The sensitivity dial.
* *Scalping Setup*: Left 10 / Right 5.
* *Swing Setup*: Left 50 / Right 25.
* **Zone Width**: Controls the vertical thickness of the S/R zone.

Visual Aesthetics 🟠
* **Markers**: Select from a library of professionally designed Unicode symbols (Diamonds ◈, Arrows ⯅/⯆, Stars ★, etc.) to mark the exact pivot candle.
* **Breakout Markers**: Visual confirmation icons (Crosses ✖, Checks ✔) appear exactly where the breakout occurred.

Professional Trading Strategies 🟠

**Strategy 1: The S/R Flip (Break & Retest)**
1. Set **Breakout Behavior** to "Role Reversal (Flip)".
2. Wait for price to break a **Red Resistance Zone**.
3. Watch the Zone turn **Blue (Support)**.
4. **Entry**: Wait for price to pull back and touch the new Blue Support zone. Look for a rejection wick.
5. **Stop Loss**: Just below the zone.

Strategy 2: Range Containment
1. Identify a market moving sideways between a parallel Blue Support and Red Resistance.
2. **Sell** at the Red Zone touch (Resistance).
3. **Buy** at the Blue Zone touch (Support).
4. **Filter**: Use the "Confirmed Only" mode to ensure the candle closes inside the range before taking a trade.

Alert System 🟠

Never miss a move. The indicator offers fully integrated alerts for automation:
* **New Level Found**: Instant notification when fresh structure is identified.
* **Breakout Alert**: When a level is breached.
* **Flip Alert**: Specific notification when Resistance becomes Support (or vice versa).
