MT5 Currency Strength Dashboard With Intraday History & Playback Feature

I am looking for an experienced MQL5 developer to build a currency strength analysis tool for MetaTrader 5, inspired by the functionality shown here:

https://www.livecharts.co.uk/currency-strength.php

The main idea is simple: calculate and display the relative strength of major forex currencies to support better trade decisions.

However, the key feature I want (which is currently missing from most strength meters) is the ability to track and replay currency strength movement during the day.

Most tools only show the current strength snapshot. I want something that also shows how strength evolved during the trading session.

Project Objective:

Build a currency strength dashboard that not only shows current strength but also records data so I can review:

• Which currency has been strongest during the session
• Which currency has been consistently weak
• How strength relationships changed over time
• Momentum shifts between currencies

Functional Requirements:

1. Currency Strength Calculation

The system should calculate strength for:

USD
EUR
GBP
JPY
AUD
CAD
CHF
NZD

Using multiple related forex pairs (developer may suggest best methodology).

Output should include:

• Strength ranking
• Numerical strength values
• Strongest vs weakest identification

2. Intraday Data Storage (Key Requirement)

The system must:

• Continuously record currency strength values
• Store data during the trading session
• Allow historical reference during the day

3. Playback Feature (Core Feature)

I want the ability to:

• Review earlier strength conditions
• Scroll back strength values
• See strength progression
• Optionally replay movement like a timeline
• Identify session leaders/laggards

Developers are free to propose the best UI approach.

4. Visualization

Preferred display options:

• Dashboard panel
• Strength table
• Line graph showing strength evolution
• Color coding for strong vs weak currencies

Clean and professional UI preferred.

Optional Enhancements (Open to ideas):

Developers may propose:

• Strength crossover alerts
• Strong vs weak pair suggestions
• Trend detection logic
• Session statistics
• Data export capability
• Strength momentum signals

Implementation Approach:

I am open to your technical recommendations such as:

• Custom Indicator
• Expert Advisor dashboard
• Hybrid architecture
• Efficient data storage method

Performance and clean code are important.

Deliverables:

• MQ5 source code
• EX5 compiled file
• Installation instructions
• Brief documentation

To Apply Please Include:

• Your proposed calculation approach
• How you would implement the historical playback feature
• Examples of similar tools you have built
• Suggested improvements (if any)
