Create an Expert Advisor for XAUUSD that opens and closes trades based on MACD signals, while skipping all trades when ADX indicates weak trend conditions.

Functional Requirements

1. Trading Instrument and Timeframe

• The EA must operate on XAUUSD.

• Timeframe should be configurable (default: 5‑minute depending on your scalping style).

2. Entry Logic (MACD-Based)

The EA must generate trade entries using MACD conditions:

• Buy Entry

  • MACD line crosses above the Signal line.

  • Optional: MACD histogram flips from negative to positive.

  • Optional: Price above a trend filter (e.g., 20 EMA).

• Sell Entry

  • MACD line crosses below the Signal line.

  • Optional: MACD histogram flips from positive to negative.

  • Optional: Price below a trend filter.

MACD parameters must be user‑configurable (Fast EMA, Slow EMA, Signal).

3. ADX Filter (Skip Trades in Weak Trends)

The EA must not open any trades when ADX is below a user‑defined threshold.

• ADX period must be configurable.

• ADX threshold must be configurable (e.g., skip trades when ADX < 20).

• When ADX is below threshold:

  • No new trades are allowed.

  • Existing trades continue normally.

This prevents entries during sideways or low‑momentum conditions.

4. Exit Logic

The EA must support multiple exit methods:

• MACD Exit

  • Opposite MACD cross closes the trade.

• Stop‑Loss and Take‑Profit

  • User‑defined SL and TP in points.

• Optional Trailing Stop

  • Can be ATR‑based or fixed‑point trailing.

  • Parameters must be configurable.

• Optional Breakeven

  • Move SL to entry after X points in profit.

5. Risk Management

• Lot size must be configurable (fixed or percentage‑based).

• Maximum number of open trades must be configurable.

• Only one trade per signal unless user enables multiple entries.

• Stop trading when Loss reach to maximum % of the equity.

6. Additional Requirements

• EA must avoid duplicate entries on the same candle.

• EA must handle spread, slippage, and news filters if enabled.

• All parameters must be adjustable from the EA settings.
