Create a MACD Expert Advisor for MetaTrader 5

Overview: We are seeking a skilled and experienced developer to create a custom Expert Advisor (EA) for MetaTrader 5 (MT5) that is based on the Moving Average Convergence Divergence (MACD) indicator. The EA should be capable of executing trades based on specific conditions involving MACD histogram crossings, MACD line and signal line crossings, and Smoothed Moving Average (SMMA) crossovers. Additionally, it should provide options for setting Stop Loss (SL) and Take Profit (TP) levels based on either the Average True Range (ATR) or fixed points, and also allow for a risk management feature for position size. The EA should also have the capability to set a unique Magic Number for identifying its trades and provide comments for user reference.

Functional Requirements:

1. MACD Histogram Crossing Zero Line:

   • The EA should activate a trade when the MACD histogram crosses the zero line, specifically when it changes the color from red to green or green to red.

2. MACD Line Crossing Signal Line:

   • The EA should activate a trade when the MACD line crosses the signal line.

3. SMMA Crossover:

   • The EA should activate a trade based on the crossover of a Smoothed Moving Average (SMMA) with an Exponential Moving Average (EMA) with a specified period of 50.

4. Stop Loss (SL) and Take Profit (TP) Options:

   • The EA should allow users to set SL and TP levels based on either the Average True Range (ATR) or fixed points.
   • If ATR-based SL and TP are enabled, the following parameters should be provided:
     • ATRPeriod: The ATR period (default: 14).
     • ATRMultiplierSL: The ATR multiplier for SL (default: 1.5).
     • ATRMultiplierTP: The ATR multiplier for TP (default: 3.0).
     • ATRTimeframe: The timeframe for calculating ATR (default: 1 Day).
     • ATRCandle: The candle to get ATR value from (e.g., Current candle).
   • If fixed points for SL and TP are enabled, the following parameters should be provided:
     • SL: Default stop-loss value in broker's points (default: 0).
     • TP: Default take-profit value in broker's points (default: 0).

5. Risk Management:

   • The EA should include a risk management feature allowing users to set the initial risk tolerance in percentage points (default: 0.5).

6. Magic Number:

   • The EA should provide an option to assign a unique Magic Number to identify its trades.

7. Comment:

   • Users should be able to add a comment for reference on the trades executed by the EA.

8. Position Management:

   • Buy positions should be closed at Sell signals.
   • Sell positions should be closed at Buy signals.

9. Position Management Tools:

   • The EA should include Position Management features such as Trailing Stop and Break-even options.

Additional Information:

• The EA should be compatible with MetaTrader 5 and developed in MQL5.
• It should be user-friendly, allowing traders to easily configure the parameters mentioned above.
• The EA should be capable of running on different currency pairs and timeframes.

Interested developers should submit proposals with details on their experience and expertise in creating custom Expert Advisors for MT5. Additionally, please provide a timeline for development and any other relevant information.
