Basic Code Example for Creating an EA in MQL5

Here is a simple example of how to create an EA that executes a basic buy trade when the conditions are met:

//+------------------------------------------------------------------+
//|                                                     SampleEA.mq5 |
//|                        Copyright 2023, MetaQuotes Software Corp. |
//|                                             http://www.metaquotes.net/ |
//+------------------------------------------------------------------+
input double LotSize = 0.1;      // Lot size for each trade
input int TakeProfit = 100;       // Take Profit in points
input int StopLoss = 100;         // Stop Loss in points

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
  {
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
   double price = SymbolInfoDouble(_Symbol, SYMBOL_BID);
   double takeProfitPrice = price + TakeProfit * _Point;
   double stopLossPrice = price - StopLoss * _Point;

   if(OrderSelect(0, SELECT_BY_POS) == false)  // Check if no open orders
     {
      OrderSend(_Symbol, OP_BUY, LotSize, price, 3, stopLossPrice, takeProfitPrice);
     }
  }
//+------------------------------------------------------------------+

Testing and Optimizing EAs

Through the strategy tester in MT5, you can simulate trades over historical data to analyze the performance of your EA. Make sure to follow best practices for backtesting strategies:

Use Quality Historical Data: The more accurate the data, the better the results will reflect future performance.
Optimize Parameters: Adjust parameters and retest multiple times to refine strategy execution.
Run Forward Tests: After backtesting, conduct forward tests with a small account to validate real-time performance.

Trailing Stop Strategies in MQL5

What are Trailing Stops?

A trailing stop is a dynamic stop-loss order that moves with the market price. Unlike fixed stop-loss orders, trailing stops adjust the stop-loss price as the market moves favorably, allowing traders to lock in profits while mitigating risks.

Implementing a Trailing Stop in MQL5

To implement a trailing stop strategy in MQL5, consider the following code snippet:

double distance = 20 * _Point; // Distance in points

// Function to modify existing orders with trailing stops
void ManageTrailingStop()
{
    for(int i = OrdersTotal() - 1; i >= 0; i--)
    {
        if(OrderSelect(i, SELECT_BY_POS))
        {
            if(OrderType() == OP_BUY)
            {
                double newStopLoss = OrderOpenPrice() + distance;
                if(Bid >= newStopLoss && OrderStopLoss() &lt; newStopLoss)
                {
                    OrderModify(OrderTicket(), OrderOpenPrice(), newStopLoss, OrderTakeProfit(), 0, clrYellow);
                }
            }
            else if(OrderType() == OP_SELL)
            {
                double newStopLoss = OrderOpenPrice() - distance;
                if(Ask  newStopLoss)
                {
                    OrderModify(OrderTicket(), OrderOpenPrice(), newStopLoss, OrderTakeProfit(), 0, clrYellow);
                }
            }
        }
    }
}

Backtesting Trailing Stops

Conducting backtests on trailing stops is critical for understanding their impact on overall trading success. By analyzing large datasets, you can determine optimal trailing distances that yield the highest profitability while managing risk.

Gold Trading Techniques Using MQL5

Understanding the Gold Market

Gold trading is often favored by traders due to its safe-haven status during economic uncertainty. It requires a unique approach, as gold exhibits different behavior compared to currency and stocks.

Strategies for Successful Gold Trading

Trend Following: Utilize moving averages to identify and ride extensions of prevailing trends.

Using MQL5 for Gold Trading

You can create EAs specifically tailored for trading gold:

input double GoldLotSize = 0.05;      // Lot size for gold trades
input double GoldTakeProfit = 50;      // Take Profit in points for gold
input double GoldStopLoss = 50;        // Stop Loss in points for gold

void TradeGold()
{
    double price = SymbolInfoDouble("XAUUSD", SYMBOL_BID);
    double takeProfitPrice = price + GoldTakeProfit * _Point;
    double stopLossPrice = price - GoldStopLoss * _Point;

    if(OrderSelect(0, SELECT_BY_POS) == false)
    {
        OrderSend("XAUUSD", OP_BUY, GoldLotSize, price, 3, stopLossPrice, takeProfitPrice);
    }
}
