TA-Lib仅返回1个周期的结果

Question

我想计算14个24小时周期的MFI。 我正在加载15个24小时时段。 在输出中，我只有1个MFI值，所有其他行的值均为0。Ta-Lib返回“成功”。 我究竟做错了什么？ 例如，当我尝试计算其他内容（例如atr）时，也会发生相同的情况。

Answer 1

如果我对MFI有误解，请纠正我，但请按照以下说明进行操作： http : //www.chart-formations.com/indicators/mfi.aspx? cat = momentum资金流量指数是一个汇总指数，如果您给出输入14个周期。

如果更改周期，例如2，则将填充阵列，但是，看起来14天是迄今为止最常见的。 所得的MFI 51表明，它在给定的时期内既没有超卖也没有超买。

看起来这是与C＃远程链接的，可以放在https://quant.stackexchange.com/中 。
