import macd from 'macd'

macd(data)

// which returns:

//   MACD: <Array>,
//   signal: <Array>,
//   histogram: <Array>
// }

• data Array.<Number> the collection of prices
• slowPeriods Number=26 the size of slow periods. Defaults to 26
• fastPeriods Number=12 the size of fast periods. Defaults to 12
• signalPeriods Number=9 the size of periods to calculate the MACD signal line.

Returns MACDGraph

• MACD Array.<Number> the difference between EMAs of the fast periods and EMAs of the slow periods.
• signal Array.<Number> the EMAs of the MACD
• histogram Array.<Number> MACD minus signal

In some countries, such as China, the three series above are commonly known as:

MACD       -> DIF
