移动平均线,Moving Average,简称MA,MA是用统计分析的方法,将一定时期内的证券价格(指数)加以平均,并把不同时间的平均值连接起来,形成一根MA,用以观察证券价格变动趋势的一种技术指标。

//MA计算公式
function calculateMA(dayCount, data) {

var result = [];
for (var i = 0, len = data.values.length; i < len; i++) {
    if (i < dayCount) {
        result.push('-');
        continue;
    }
    var sum = 0;
    for (var j = 0; j < dayCount; j++) {
        sum += data.values[i - j][1];
    }
    result.push(+(sum / dayCount).toFixed(3));
}
return result;

需要注意数据模型的格式,不同的数据模型的计算大同小异,注意数据对应就好
