这段MQL4代码实现了一个简单的自动交易策略，它包含以下功能：

• 使用魔术码 (MAGIC_NUMBER) 来区分不同的订单。
• 如果没有持仓，则分别挂多单和空单，两者价格与当前价格相差100点。
• 多单成交后，每上涨100点就加仓，最多加仓5次；如果价格下跌超过100点，则开仓反向0.5手空单进行锁仓，并随着下跌不断加仓空单。
• 空单成交后的逻辑与多单类似，只是方向相反。
• 当所有订单的总利润达到预设目标 (PROFIT_TARGET) 时，自动平掉所有订单。

请注意，这只是一个简单的示例，您需要根据自己的需求和风险承受能力进行修改和优化，并在模拟账户上充分测试后再进行实盘交易。
