Question

类似于create an OHLC data from Date, time, price using Javascript，人们如何接受将基本交易数据转换为OHLC（或开盘价，最高价，最低价，收盘价）并将其应用于生成1分钟OHLC的理论？除此之外，我还无法通过提供的代码将纪元时间戳适应ISODate。

var data = [{
    "tid": 283945,
    "date": 2018-08-02T04:24:53Z,
    "amount": "0.08180000",
    "price": "501.30"
}, {
    "tid": 283947,
    "date": 2018-08-02T04:24:53Z,
    "amount": "0.06110000",
    "price": "490.66"
},
...
];

function convertToOHLC(data) {
    // What goes here?
}
convertToOHLC(data);

我创建了一个示例，根据您的要求如何将数据转换为ohlc：

TypeError: Using a `tf.Tensor` as a Python `bool` is not allowed. Use `if t is not None:` instead of `if t:` to test if a tensor is defined, and use TensorFlow ops such as tf.cond to execute subgraphs conditioned on the value of a tensor.

在JavaScript中将报价数据转换为1分钟OHLC（打开，高，低，关闭）？
