High-Performance MQL4 Expert Advisor for Advanced Trading Techniques

You are to generate a fully integrated, high-performance Expert Advisor (EA) coded in MQL4 for MetaTrader 4 that implements all the advanced trading techniques and features outlined below.
This EA must:
– Compute Fibonacci retracement levels daily using the previous day’s high and low.
– Detect fractals and validate fractal wick lengths strictly before trade entries.
– Monitor volatility in real-time using:
– ATR
– Bollinger Bands width
– Spread analysis
– Optimize trade timing and frequency based on the above metrics.
– Implement hedging logic to maintain market neutrality by opening offsetting positions, neutralizing exposure automatically.
– Include institutional-style high-frequency scalping strategies such as:
– Mean reversion
– Order flow scalping
– Fibonacci and fractal signals
– Arbitrage opportunities
– Dynamically adjust trade frequency based on current market volatility:
– More trades during stable, low volatility periods
– Fewer trades during high volatility
– Use adaptive trailing stops that respond dynamically to evolving market conditions to protect profits and limit losses.
– Employ adaptive risk management ensuring losses do not exceed $0.50 per lot per trade by:
– Dynamically adjusting stop-loss levels
– Using pending orders
– Implementing trailing stops
– Setting immediate break-even when appropriate
– Use BuyStop/SellStop orders configured for ultra-fast market execution and automatic, intelligent order management.
– Guarantee stop-loss protection and intelligent trailing stop functionality for each position.
– Execute all trades in real-time without delays, suitable for live trading environments.
Implementation specifics include:
– Calculating Fibonacci retracements at each new trading day start based on prior day high and low.
– Strict fractal detection using wick length validation.
– Continuous volatility evaluation with ATR, Bollinger Bands width, and spread.
– Automatic hedging to maintain market neutrality.
– Integration of scalping and HFT strategies with:
– Mean reversion
– Order flow analysis
– Fibonacci/fractal signals
– Arbitrage
– Dynamic trailing stop adjustments based on volatility and price movement.
– Risk per trade capped at $0.50 per lot through dynamic stop-loss sizing.
– Robust handling of volatility spikes, market gaps, and spread widening.
– Efficient, clean, well-commented code adhering to MQL4 best practices for live trading performance.
– Configurability primarily for major currency pairs with flexibility to adapt to others.

4. Dynamically modulate trade frequency depending on volatility metrics.
5. Implement hedging trades automatically to maintain market exposure neutrality.
6. Apply trailing stops that update dynamically with market moves.
7. Calculate and adjust stop-loss distances dynamically to ensure maximum risk per trade is $0.50 per lot.
8. Place, modify, and close trades instantly without delay.
