Darwas box long short HHT

Darvas Box Long/Short EA - Version 3.2

Overview
The Darvas Box Long/Short EA is a robust, automated trading robot built for MetaTrader 4 (MT4), inspired by Nicolas Darvas' legendary breakout strategy from the 1950s. It scans for momentum-driven breakouts (long) and breakdowns (short) using dynamic "boxes" formed from recent price highs and lows, enhanced with an ATR-based buffer for volatility filtering. This EA is fully universal—compatible with any currency pair (e.g., EURUSD, GBPUSD, XAUUSD) and any timeframe (M1 to Daily)—with no hardcoded restrictions. Simply attach it to a chart, and it adapts automatically.

With built-in risk management, position limits, and visual charting, it's ideal for traders seeking a hands-free, trend-following system that balances opportunity with capital protection. It executes trades 24/7, focusing on high-probability setups while logging results to CSV for easy analysis.

Key Advantages and Features

• Universal Adaptability: Seamlessly works across all symbols and timeframes without modifications—perfect for diversified portfolios or scalping to swing trading.

• Long and Short Trades: Captures upside momentum with buys on upper box breakouts and downside with sells on lower breakdowns, enabling balanced exposure in any market direction.

• ATR-Enhanced Entries: Adds a flexible buffer (ATR value × multiplier) to box edges, filtering out noise and adjusting to volatility for more reliable signals.

• 1:2 Risk-Reward Ratio: Automatically sets take-profit at twice the stop-loss distance, promoting positive expectancy where winners can outweigh losers.

• Smart Risk Management: Dynamically calculates lot sizes to risk only a user-defined percentage of account balance per trade, protecting against large drawdowns.

• Position Control: Enforces a strict one-position limit (long or short) to prevent over-trading and compounded risk.

• Visual Feedback: Draws the active Darvas Box on your chart in real-time for transparent monitoring of trade zones.

• CSV Trade Logging: Exports detailed trade history (ticket, type, lots, times, profit) to a CSV file upon EA removal, for post-analysis in tools like Excel.

• Efficient and Reliable: Low CPU usage, no martingale or grid risks—pure breakout logic with predefined rules for consistent performance.
