mql语言macd日金叉报警 日死叉报警

以下是MQL语言中MACD日金叉和日死叉报警的示例代码：

MACD日金叉报警：

// 定义MACD参数
input int fastEMA = 12;
input int slowEMA = 26;
input int signalEMA = 9;

// 定义变量
double macdCurrent, macdPrevious;
double signalCurrent, signalPrevious;

// 初始化指标
int OnInit() {
   // 计算MACD指标
   ArraySetAsSeries(true);
   SetIndexBuffer(0, macdBuffer);
   SetIndexBuffer(1, signalBuffer);
   SetIndexStyle(0, DRAW_LINE);
   SetIndexStyle(1, DRAW_LINE);
   SetIndexLabel(0, "MACD");
   SetIndexLabel(1, "Signal");

   // 计算初始值
   int limit = Bars - IndicatorCounted();
   for (int i = limit; i >= 0; i--) {
      macdCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i);
      macdPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i + 1);
      signalCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i);
      signalPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i + 1);
      macdBuffer[i] = macdCurrent;
      signalBuffer[i] = signalCurrent;
   }
   return INIT_SUCCEEDED;
}

// 循环计算
void OnCalculate(const int rates_total, const int prev_calculated, const datetime &time[],
                 const double &open[], const double &high[], const double &low[], const double &close[],
                 const long &tick_volume[], const long &volume[], const int &spread[]) {
   int limit = rates_total - prev_calculated;
   for (int i = limit; i >= 0; i--) {
      macdCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i);
      macdPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i + 1);
      signalCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i);
      signalPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i + 1);
      macdBuffer[i] = macdCurrent;
      signalBuffer[i] = signalCurrent;

      // 判断金叉
      if (macdCurrent > signalCurrent && macdPrevious < signalPrevious) {
         Alert("MACD日金叉");
      }
   }
}

MACD日死叉报警：

// 定义MACD参数
input int fastEMA = 12;
input int slowEMA = 26;
input int signalEMA = 9;

// 定义变量
double macdCurrent, macdPrevious;
double signalCurrent, signalPrevious;

// 初始化指标
int OnInit() {
   // 计算MACD指标
   ArraySetAsSeries(true);
   SetIndexBuffer(0, macdBuffer);
   SetIndexBuffer(1, signalBuffer);
   SetIndexStyle(0, DRAW_LINE);
   SetIndexStyle(1, DRAW_LINE);
   SetIndexLabel(0, "MACD");
   SetIndexLabel(1, "Signal");

   // 计算初始值
   int limit = Bars - IndicatorCounted();
   for (int i = limit; i >= 0; i--) {
      macdCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i);
      macdPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i + 1);
      signalCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i);
      signalPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i + 1);
      macdBuffer[i] = macdCurrent;
      signalBuffer[i] = signalCurrent;
   }
   return INIT_SUCCEEDED;
}

// 循环计算
void OnCalculate(const int rates_total, const int prev_calculated, const datetime &time[],
                 const double &open[], const double &high[], const double &low[], const double &close[],
                 const long &tick_volume[], const long &volume[], const int &spread[]) {
   int limit = rates_total - prev_calculated;
   for (int i = limit; i >= 0; i--) {
      macdCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i);
      macdPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_MAIN, i + 1);
      signalCurrent = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i);
      signalPrevious = iMACD(NULL, 0, fastEMA, slowEMA, signalEMA, PRICE_CLOSE, MODE_SIGNAL, i + 1);
      macdBuffer[i] = macdCurrent;
      signalBuffer[i] = signalCurrent;

      // 判断死叉
      if (macdCurrent < signalCurrent && macdPrevious > signalPrevious) {
         Alert("MACD日死叉");
      }
   }
