talib.MACD

```talib.MACD()```函数的返回值为：二维数组。
array

talib.MACD(inReal)
talib.MACD(inReal, optInFastPeriod)
talib.MACD(inReal, optInFastPeriod, optInSlowPeriod)
talib.MACD(inReal, optInFastPeriod, optInSlowPeriod, optInSignalPeriod)

```inReal```参数用于指定K线数据。
inReal
true
{@struct/Record Record}结构数组、数值数组
```optInFastPeriod```参数用于设置快周期，默认值为12。
optInFastPeriod
false
number
```optInSlowPeriod```参数用于设置慢周期，默认值为26。
optInSlowPeriod
false
number
```optInSignalPeriod```参数用于设置信号周期，默认值为9。
optInSignalPeriod
false
number

```javascript
function main() {
    var records = exchange.GetRecords()
    var ret = talib.MACD(records)
    Log(ret)
}

import talib
def main():
    records = exchange.GetRecords()
    ret = talib.MACD(records.Close)
    Log(ret)

void main() {
    auto records = exchange.GetRecords();
    auto ret = talib.MACD(records);
    Log(ret);
}

MACD()函数在talib库文档中的描述为：MACD(Records[Close],Fast Period = 12,Slow Period = 26,Signal Period = 9) = [Array(outMACD),Array(outMACDSignal),Array(outMACDHist)]
