Here is a simple example of an MQL4 robot using a candlestick pattern to open trades. This robot will enter a BUY trade if the current candle is bullish (green) and enter a SELL trade if the current candle is bearish (red):
int start()
{
// Get the closing price of the current candle
double currentClose = Close[0];
// Get the opening price of the current candle
double currentOpen = Open[0];
// Check if the current candle is bullish or bearish
bool isBullish = currentClose > currentOpen;
// If the current candle is bullish, open a BUY trade
if (isBullish) {
int ticket = OrderSend(Symbol(), OP_BUY, 0.1, Ask, 0, Bid - StopLoss * Point, Bid + TakeProfit * Point, "Buy Order", 0, 0, Green);
if (ticket > 0) {
Print("Buy order opened successfully. Ticket:", ticket);
} else {
Print("Buy order failed to open. Error code:", GetLastError());
}
}
// If the current candle is bearish, open a SELL trade
else {
int ticket = OrderSend(Symbol(), OP_SELL, 0.1, Bid, 0, Ask + StopLoss * Point, Ask - TakeProfit * Point, "Sell Order", 0, 0, Red);
if (ticket > 0) {
Print("Sell order opened successfully. Ticket:", ticket);
} else {
Print("Sell order failed to open. Error code:", GetLastError());
}
}
return 0;
}
In this example, we use two variables
currentClose and
currentOpen to retrieve the closing and opening prices of the current candle. Then, we check whether the current candle is bullish or bearish by comparing the closing price and the opening price.
+ If the current candle is bullish, we utilize the OrderSend() function to open a BUY trade. The OP_BUY parameter is used to specify the order type as BUY. The Ask parameter is employed to set the current buying price of the currency pair. The Bid - StopLoss * Point parameter is used to define the Stop Loss price for the BUY trade. The Bid + TakeProfit * Point parameter is used to determine the Take Profit price for the BUY trade.
+ If the current candle is bearish, we employ the OrderSend() function to open a SELL trade. The OP_SELL parameter is used to specify the order type as SELL. The Bid parameter is utilized to set the current selling price of the currency pair. The Ask + StopLoss * Point parameter is employed to set the Stop Loss price for the SELL trade. The Ask - TakeProfit * Point parameter is used to define the Take Profit price for the SELL trade.
+ You can modify the values of Stop Loss and Take Profit by changing the values of the StopLoss and TakeProfit variables. Additionally, you can add other conditional checks to determine the opening and closing of trades in your own robot.
