Precision Limit Zone Expert Advisor (MT4/MT5)

I am looking to develop a custom Expert Advisor (EA) for MetaTrader (MT4/MT5) based on a defined technical analysis strategy and flexible risk management rules.

The EA should operate on a chart and timeframe that I manually specify, with the ability to adapt its behavior dynamically when the timeframe is changed.

Core Strategy Logic

The EA will execute trades based on predefined technical analysis zones, specifically:

• Identification of buy limit and sell limit zones
• Entries triggered when price reaches these zones
• Logic can be based on a combination of price action and selected indicators

Risk & Trade Management

The EA must include:

• Fixed Stop Loss (SL) and Take Profit (TP) levels
• Advanced Trailing Stop functionality (precise and customizable)
• Configurable risk management system, including:
• Fixed lot size
• Automatic lot sizing based on account equity (user-defined rules)

Indicators & Analysis

• Ability to integrate and use built-in or custom indicators directly within the EA
• Indicator parameters must be fully configurable
• Signals can be combined (e.g., confluence-based entries)

Execution & Filters

• Trading time filter (only trade during specific sessions/hours)
• Ability to enable/disable trading on certain days
• Optional filters (spread, volatility, etc.)

Flexibility & Inputs

• All key parameters must be externally configurable (inputs)
• EA must adapt when switching between timeframes without needing reinstallation
• Adjustable limits and behavior depending on selected timeframe

Additional Requirements

• Clean and efficient code
• Optimized for backtesting and forward testing
• Detailed logging for trade decisions (for debugging and optimization)
• Stable performance across different market conditions

If needed, I can provide:

• Exact definition of entry zones
• Indicator combinations and parameters
• Example scenarios / backtest expectations
