Td Ameritrade 下载历史数据 endDate startDate

Question

我不知道如何获取特定日期的数据。在我的代码中使用年线，我知道给定日期的毫秒值。

1612159200000.00 AAPL 2/1/2021 6:00

1612418400000.00 AAPL 2/4/2021 6:00

但是将这些值放入代码中是行不通的

data=get_price_history(symbol=i, endDate=1612418400000 , startDate=1612159200000,  frequency=1, frequencyType='daily')

import requests
import pandas as pd
import time
import datetime

# tickers_list= ['AAPL', 'AMGN', 'AXP']
# print(len(tickers_list))

key = '****'

def get_price_history(**kwargs):

    url = 'https://api.tdameritrade.com/v1/marketdata/{}/pricehistory'.format(kwargs.get('symbol'))
    params = {}
    params.update({'apikey': key})

    for arg in kwargs:
        parameter = {arg: kwargs.get(arg)}
        params.update(parameter)

    return requests.get(url, params=params).json()

tickers_list= ['AAPL', 'AMGN','WMT']
for i in tickers_list:

    # get data 1 year 1 day frequency -- good
    # data=get_price_history(symbol=i, period=1, periodType='year', frequency=1, frequencyType='daily')
    
    data=get_price_history(symbol=i, endDate=1612418400000 , startDate=1612159200000,  frequency=1, frequencyType='daily') 

    historical['date'] = pd.to_datetime(historical['datetime'], unit='ms')
    info=pd.DataFrame(data['candles'])

    historical=pd.concat([historical,info])

historical

来自the Ameritrade Price History API documentation：

6 Months / 1 Day, including today's data:

https://api.tdameritrade.com/v1/marketdata/XYZ/pricehistory?periodType=month&frequencyType=daily&endDate=1464825600000

Note that periodType=month is specified because the default periodType is day which is not compatible with the frequencyType daily

所以您的代码中的这一行似乎是：

data=get_price_history(symbol=i, endDate=1612418400000 , startDate=1612159200000,  frequency=1, frequencyType='daily')

缺少有效的 periodType 参数。尝试：

data=get_price_history(symbol=i, endDate=1612418400000 , startDate=1612159200000, frequency=1, periodType='month', frequencyType='daily')
