MACD金叉做多策略：自动交易补仓与锁仓

本策略使用魔术码'92133'，在MACD金叉时开仓多单，初始手数为0.5手。

• 价格上涨100微点以上，以持仓第一个订单手数的0.6倍进行补仓做多。
• 如果当前价格低于第一个订单100微点以下，则以0.5手数进行锁仓做空。
• 价格下跌100微点，以持仓第一个订单手数的0.6倍进行补仓做空。
• 当多空总盈利达到40美金时，自动平仓。

以下是将您的设定转换为MQ4（MetaQuotes 4的编程语言）的示例代码：

// 定义常量
#define MAGIC_NUMBER 92133
#define INITIAL_LOTS 0.5
#define PROFIT_TARGET 40
#define MIN_FLUCTUATION MarketInfo(Symbol(), MODE_POINT) * 100

// 定义变量
double currentLots = 0;
double totalProfit = 0;

void OnTick()
{
    // 检查当前魔术码下的持仓是否为0
    bool hasPosition = false;
    for (int i = OrdersTotal() - 1; i >= 0; i--)

        {
            hasPosition = true;
            break;
        }
    }

    // MACD金叉做多
    if (!hasPosition && iMACD(NULL, 0, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, 0) > iMACD(NULL, 0, 12, 26, 9, PRICE_CLOSE, MODE_SIGNAL, 0))
