Language: MQL5
Deliverables:

Well-structured and commented code

User-defined input parameters for customization

On-screen panel display with status checks

✅ 1. HTF Alignment – Market Structure Detection
Objective:
Detect whether the current price on the Daily Timeframe is in Premium or Discount zone based on the latest Swing High and Swing Low.

Requirements:

Automatically detect swing high/low on the Daily chart using fractal logic or price structure.

Define the range: Latest Swing High to Swing Low.

Calculate current price position relative to this range.

Premium: Price > 0.5 (midpoint of the range)

Discount: Price < 0.5

Display output on panel: HTF: Premium or HTF: Discount.

✅ 2. Liquidity Sweep Detection
Objective:
Identify liquidity sweeps in relation to market structure and trade direction.

Key Concepts:

Liquidity Sweep: When price briefly breaks a swing high/low with a wick and reverses.

Sweep + Break of Structure (BOS) confirmation:

Bullish Scenario:

Sweep below recent swing low

Followed by a close above recent swing high → Confirm Bullish BOS

Bearish Scenario:

Sweep above recent swing high

Followed by a close below recent swing low → Confirm Bearish BOS

Detection Rules:

A sweep must have a candle wick breach a previous swing point.

Price must close back inside or reverse sharply.

BOS must be body close-based, not just wick.

Display on Panel:

"Sweep + BOS: Bullish Confirmed" or "Sweep + BOS: Bearish Confirmed"

Show both if detected on different legs.

✅ 3. BOS + Imbalance (Fair Value Gap Detection)
Objective:
Detect when a Break of Structure (BOS) is followed by a Fair Value Gap (FVG).

Definitions for Developer:

BOS:

Bullish = Body closes above last swing high

Bearish = Body closes below last swing low

FVG / Imbalance: A price gap between candles where the middle candle’s low > next candle’s high (or vice versa)

Logic:

Detect BOS

Immediately check for nearby FVGs

If both exist → Mark it as a valid setup

Display on Panel:

“BOS + FVG: Bullish/ Bearish Detected”

Option to highlight FVG zones visually on chart (optional)

✅ 4. Fibonacci Retracement Overlay
Objective:
Draw Fibonacci retracement between latest Swing High and Swing Low

Levels to be marked:

0.62

0.71

0.79

Display Options:

Optional toggle to show/hide Fib levels

Use different colors for each level (e.g., 0.62 - Green, 0.71 - Orange, 0.79 - Red)

✅ 5. On-Chart Panel
Position: Top-right corner (user adjustable)
Panel Displays:

HTF Alignment: Premium / Discount

Liquidity Sweep Detected: Yes / No

BOS Detected: Bullish / Bearish

BOS + FVG: Confirmed / Not Confirmed

Fib Levels: Optional toggle

Customization Inputs:

Swing sensitivity (number of bars for swing detection)

Timeframe to assess HTF alignment (default: D1)

Colors and fonts

Toggle display elements (fib, panel, labels)

📌 Notes for Developer
Use modular code: separate functions for BOS, Sweep, FVG, etc.

Make logic compatible with both live and historical bars

Prioritize performance and avoid repainting for historical values

Ensure proper debugging and provide test cases if possible
