Specification - Multi-timeframe Supply and Demand indicator

looking for a highly experienced mql5 developer to build a professional trading ea based on multi timeframe top down analysis and market structure concepts

the system should combine higher timeframe context with lower timeframe execution and provide both precise logic and clean visual representation on chart

⸻

core requirements

 • implementation of multi timeframe logic higher timeframe bias combined with lower timeframe execution

 • detection of supply and demand zones across higher timeframes

 • market structure confirmations including bos choch or similar concepts

 • trend filtering using ema or equivalent logic

 • structured and modular code allowing future adjustments and optimization

 • stable performance in both backtesting and live conditions

⸻

ui and visualization requirements

 • clean and user friendly on chart interface

 • clear visualization of supply and demand zones

 • display of market structure events bos choch

 • visual indication of trend bias

 • ema displayed on chart

 • ability to enable disable specific visual elements

 • well organized input parameters for easy customization

⸻

additional expectations

 • code must be clean well structured and easy to maintain

 • no hardcoded values all logic should be configurable

 • support for optimization in strategy tester

 • proper logging for debugging and validation

⸻

developer requirements

preference for developers with proven experience in

 • smart money concepts

 • supply and demand trading systems

 • multi timeframe logic

 • building advanced mql5 indicators or eas with visual interfaces

please explain briefly how you would approach
