예를 들어, GetRecords() 는 K선 데이터를 얻고, TA.EMA는 평균선 데이터를 얻고, 그러면
var records = exchange.GetRecords(PERIOD_M15)
if (records && records.length > 12) {
var ema = TA.EMA(records, 12)
}
왜 15분 K 선은 12일 평균선에 쓰일 수 있을까요?

15分钟周期的K线, 这话没毛病. 但是那个12 不是12天, 哥们, 是12根K线, 一根K线代表15分钟. 没有足够的K线, 无法算EMA, var ema = TA.EMA(records, 12)
这个代码的变量名该改改,你就不容易疑惑了. 真正的意思是: var ema12 =TA.EMA(records, 12) // 这句代码就是算出EMA12 均线的值.
