Expert Advisor (EA) for XAUUSD (Gold) Trading

Platform: MetaTrader 5 (MT5)
Symbol: XAUUSD (Gold)
Type: Fully automated trading system

Core Trading Logic

The EA should execute trades based on a multi-strategy approach, ensuring a high probability of success. It must incorporate:
✅ Trend Confirmation on Higher Timeframes – Uses H4, Daily, or Weekly charts to confirm the trend before executing trades on lower timeframes (M5, M15, or M30).
✅ Risk-Reward Optimization – Every trade should risk 5% of the account balance with a minimum 1:2 risk-reward ratio (i.e., 10% potential reward).
✅ Stop-Loss Protection – All trades must be secured with a stop loss to prevent large drawdowns.
✅ No Risky Strategies – Martingale, Grid, Averaging, and similar high-risk strategies are NOT allowed.
✅ Multiple Strategies Combined – The EA should use a mix of the following strategies:

• Moving Average Crossovers for trend identification
• Price Action & Breakout Trading (support/resistance, candlestick patterns)
• Momentum Indicators (RSI, MACD, or ADX for strength confirmation)
• ATR-based Volatility Filter to avoid low-volatility conditions

Risk & Money Management

✅ Fixed or Dynamic Lot Sizing – The EA should allow selecting between a fixed lot size or dynamic lot size based on account balance.
✅ Risk Per Trade – The EA must calculate lot size dynamically to ensure that only 5% of the balance is at risk per trade.
✅ Trailing Stop Feature – Once in profit, a trailing stop should be used to maximize gains.
✅ Break-even Mechanism – The EA should secure partial profits by moving the stop loss to break even when the trade reaches a certain percentage of the target.

Trading Timeframes & Flexibility

✅ Higher Timeframe Confirmation – The EA must allow users to select a higher timeframe (H1, H4, D1) for trend validation before placing trades on lower timeframes.
✅ Lower Timeframe Execution – Trades should be executed based on signals from M5, M15, or M30, with a confirmation filter from the higher timeframe.
✅ User-Controlled Parameters – Users should be able to choose which timeframes to use for confirmation and execution.

News Filter Integration

✅ The EA must include a news filter to avoid trading before and during high-impact news events.
✅ It should pull real-time news from an economic calendar (e.g., Forex Factory, Investing.com, or MQL5 news API).
✅ Adjustable settings for news impact level (High, Medium, Low) and minutes before & after news events to pause trading.

🔹 Number of Trades: Limit the maximum open trades at a time.
