Creating Expert Advisors in MQL5

How to Build a Basic Expert Advisor

To kickstart your journey into MQL5 development, let’s create a simple EA that executes trades based on moving averages. Here’s a sample code snippet to illustrate the structure:

//+------------------------------------------------------------------+
//|                                               Moving Average EA   |
//|                        Copyright 2023, MetaQuotes Software Corp. |
//|                                             https://www.mql5.com |
//+------------------------------------------------------------------+
input int shortMA = 10; // Short MA period
input int longMA = 30;  // Long MA period
double shortMovingAverage, longMovingAverage;

void OnTick() {
    shortMovingAverage = iMA(NULL, 0, shortMA, 0, MODE_SMA, PRICE_CLOSE, 0);
    longMovingAverage = iMA(NULL, 0, longMA, 0, MODE_SMA, PRICE_CLOSE, 0);

    if (shortMovingAverage > longMovingAverage) {
        // Check if no open buy orders
        if (PositionsTotal() == 0) {
            // Open a buy order
            double lotSize = 0.1;
            double price = NormalizeDouble(Ask, _Digits);
            OrderSend(Symbol(), OP_BUY, lotSize, price, 3, 0, 0, "MA Buy", 0, 0, Green);
        }
    } else if (shortMovingAverage < longMovingAverage) {
        // Check if no open sell orders
        if (PositionsTotal() == 0) {
            // Open a sell order
            double lotSize = 0.1;
            double price = NormalizeDouble(Bid, _Digits);
            OrderSend(Symbol(), OP_SELL, lotSize, price, 3, 0, 0, "MA Sell", 0, 0, Red);
        }
    }
}

This EA utilizes two simple moving averages (SMAs) as entry signals and executes buy or sell orders based on their crossovers. It’s a basic illustration that can be expanded with more features, such as risk management and trailing stops.

Trailing Stop Strategies in MQL5

Understanding Trailing Stops

Trailing stops are a dynamic risk management tool that locks in profits while allowing a trade to continue benefiting from favorable market movements. Implementing trailing stops in your EAs can enhance their performance significantly.

How to Implement Trailing Stops

Here’s how you can add a trailing stop function to your EA:

// Function to set trailing stop
void SetTrailingStop(double trailingStopOffset) {
    for(int i = PositionsTotal() - 1; i >= 0; i--) {
        if(PositionGetSymbol(i) == Symbol()) {
            double newStopLoss = PositionGetDouble(POSITION_PRICE_OPEN) + trailingStopOffset;
            if(PositionGetDouble(POSITION_SL) < newStopLoss) {
                OrderModify(PositionGetInteger(POSITION_TICKET), 0, newStopLoss, 0, 0, clrNONE);
            }
        }
    }
}

In this example, the function checks all open positions and adjusts the stop loss level if the market price moves favorably. You can call this function in the OnTick handler of your EA.

Gold Trading Techniques Using MQL5

Why Trade Gold?

Gold has long been a coveted asset for traders due to its reliability as a safe-haven investment. With MQL5, traders can automate their gold trading strategies efficiently while profiting from market volatility.

Implementing Gold Trading Strategies

input double riskPercentage = 1.0; // Risk per trade in percentage
input int takeProfit = 50; // Take profit in pips
input int stopLoss = 50; // Stop loss in pips

void OnTick() {
    double price = SymbolInfoDouble(Symbol(), SYMBOL_BID);
    double lotSize = CalculateLotSize(price, riskPercentage);

    if (ConditionsToBuy()) {
        OrderSend(Symbol(), OP_BUY, lotSize, price, 3, price - stopLoss * _Point, price + takeProfit * _Point, "Gold Buy", 0, 0, clrGold);
    } else if (ConditionsToSell()) {
        OrderSend(Symbol(), OP_SELL, lotSize, price, 3, price + stopLoss * _Point, price - takeProfit * _Point, "Gold Sell", 0, 0, clrGold);
    }
}

This EA uses a risk-based lot size calculation while managing take profit and stop loss levels. You can further refine the entry conditions (ConditionsToBuy and ConditionsToSell) based on your analysis.

Backtesting Strategies in MQL5

Significance of Backtesting

Backtesting is an essential part of MQL5 development, allowing traders to validate their strategies against historical data. A robust backtesting process can uncover potential flaws in a trading strategy before it is deployed in a live environment.

Example of Backtesting an EA

Utilizing the built-in backtesting capabilities in MT5, you can analyze the performance of your EA meticulously. Ensure you:

• Use a diverse dataset covering various market conditions.
• Evaluate performance metrics like the Sharpe ratio, drawdown, and profit factor.

// Backtesting in MQL5
input double step = 0.1; // Step for optimization

void OnTester() {
    double totalProfit = 0;
    for (int i = 0; i < OrdersHistoryTotal(); i++) {
        ulong ticket = OrderGetTicket(i);
        totalProfit += OrderGetDouble(ORDER_PROFIT);
    }
    Print("Total Profit from Backtest: ", totalProfit);
}
