均线交叉ea源码（均线指标源码）
以下是一段关于外汇均线交易的EA代码（适用于MT4平台），满足您提出的交易逻辑：当10日均线和30日均线出现金叉后，价格回落至10日均线时开仓做多，并设置止损和止盈。

double MA30 = SimpleMovingAverage(Symbol(), PERIOD, 30); // Calculate 30-period simple moving average
double price = Close; // Current price
double currentPeriodClose = iBarShift(PERIOD, CLOSE); // Current bar close price shifted to the beginning of the period for comparison with moving averages
if (MA30 > MA10 && MA10 > price && price > currentPeriodClose) { // Crossover and price condition to detect golden cross
if (currentPeriodClose < MA10) { // Price fall to 10-day MA line, enter long position
OrderSend(Symbol(), OP_BUY, Lots, currentPeriodClose, MA10 + Slippage, DateTimePeriodSet(MINUTE), 0); // Buy order with stop loss and take profit (not implemented in this code snippet)
}
} else if (OrderSendDone()) { // If order is filled, add code for stop loss and take profit placement here
// Place stop loss and take profit orders (not implemented in this code snippet)
} else { // If conditions are not met or order is not filled, do nothing or exit the function/expert advisor accordingly
return; // Exit the function or expert advisor if necessary
}
}
