✅ Job Advert: MQL5 Developer – News Event Dashboard Indicator & API Class

Project Summary
I’m seeking a professional MQL5 developer to create a modern, stylish news event indicator and a supporting class API for integration into Expert Advisors. The indicator will pull high-impact news events (e.g., from Forex Factory) and display them visually on the chart, with colour-coded severity and time proximity. It must work across all relevant currencies or assets, based on a JSON config file, aggregating across multiple symbols news as per config file.

🧩 What You’ll Build

🧾 1. News Indicator (MQL5)

A chart indicator that:

• Appears in Chart Window 1 (subwindow at bottom)
• Displays a horizontal traffic-light line:
• 🟢 Green = No news in ±30 minutes
• 🟠 Orange = Upcoming or just past red news event (±30 minutes)
• 🔴 Red = High-impact news right now
• Uses JSON config to define the list of currencies/symbols of interest
• Annotates the timeline visually with:
• Event name, time, currency
• Impact level (must show "Red" ones at a minimum)
• Optional: clicking annotation opens the related news URL (if supported by MT5)

🧑‍💻 2. Supporting News Class API (MQL5)

This class (e.g. Class_NewsManager.mqh) must allow EA code to easily query:

// Called in EA code

bool IsHighImpactNewsNow();

bool IsWithinNewsBufferWindow();

datetime TimeOfNextHighImpactNews();

CArrayObj *GetUpcomingNews(string symbol);  // Returns event objects

It should parse the same JSON file as the indicator and share a unified logic.

⚙️ Config File (news_config.json)

Example:

json

{

  "symbols": ["USD", "EUR", "GBP", "AUD", "CAD", "JPY"],

  "impact": ["high"],

  "buffer_minutes": 30,

  "news_source": "forexfactory"

}

  Used for filtering symbols/currencies

  Used for deciding blackout window timing

  May include URLs if the news source supports them

🔗 News Source Integration

You may use:

• ForexFactory (preferred)
• Investing.com
• JBlanked.com
• Polygon.io

Requirements:

• Use WebRequest to retrieve and parse JSON or HTML
• Auto-refresh data periodically (e.g., every 30–60 minutes)
• Include fallback/default offline cache if news is temporarily unavailable

✨ Visual Requirements

• Modern look, clean fonts
• Subwindow chart element like a timeline bar with news markers
• Hover/click to display more info
• Optional: click-through to browser URL if possible

🔐 Requirements

• Must be MQL5-native with full source code provided
• Must be EA-compatible (allowing cross-calls to the class from an EA)
• Must be efficient (minimal CPU/memory)
• Clean, well-documented code

📦 Deliverables

• NewsDashboardIndicator.mq5
• Class_NewsManager.mqh
• news_config.json (with sample file)
• Example .mq5 EA or script showing API class usage
• All source code in plain MQL5

📆 Timeline & Budget

• Timeline: ~1–5 days ideal
• Budget: Flexible depending on complexity (news parsing & click support)

📝 To Apply

Please provide:

• Your approach to parsing Forex Factory or equivalent
• Example MQL5 indicators using WebRequest or subwindow visualisations
• Confirmation you’ll deliver both the indicator and class, with full MQL5 source code
