talib.DX

talib.DX()函数用于计算Directional Movement Index (动向指数)。

talib.DX()函数的返回值为：一维数组。 array

talib.DX(inPriceHLC) talib.DX(inPriceHLC, optInTimePeriod)

inPriceHLC参数用于指定K线数据。 inPriceHLC true {@struct/Record Record}结构数组 optInTimePeriod参数用于设置周期，默认值为14。 optInTimePeriod false number

function main() {
    var records = exchange.GetRecords()
    var ret = talib.DX(records)
    Log(ret)
}

import talib
def main():
    records = exchange.GetRecords()
    ret = talib.DX(records.High, records.Low, records.Close)
    Log(ret)

void main() {
    auto records = exchange.GetRecords();
    auto ret = talib.DX(records);
    Log(ret);
}

DX()函数在talib库文档中的描述为：DX(Records[High,Low,Close],Time Period = 14) = Array(outReal)
