How to get the same CSV data as the sample file of the book?

Takeshi.Matsuda

Please tell me the contents of the following csv file introduced in this book and the EIKON API Code to get the same data. This book does not describe how to obtain the data, but instead provides EIKON data as a sample file. With "get_timeseries" I couldn't reproduce the exact same data.

• Book Name : Python for Finance, 2nd Edition [Book] - O'Reilly
• CSV : tr_eikon_eod_data.csv (Data excerpt)

• Code I created (The date data is slightly different from the sample.)

data = ek.get_timeseries(['AAPL.O', 'MSFT.O', 'INTC.O', 'AMZN.O', 'GS.N',' SPY', '.SPX', '.VIX', 'EUR=', 'XAU=', 'GDX', 'GLD'],
                         ['CLOSE'],
                         '2010-1-1','2020-10-1')
data

• Result (Where should I modify the code to get the same result as this?)

ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

@Takeshi.Matsuda You should be aware of the API limits - you can find these in this document. You will notice that the get_timeseries API call has a limit of '3,000 data points (rows) for interday intervals and 50,000 data points for intraday intervals. This limit applies to the whole request, whatever the number of requested instrument.'

Please try this code which iterates across the instrument list to get the correct data without truncation due to limits.

import eikon as ek
import pandas as pd
import numpy as np

instruments = ['AAPL.O', 'MSFT.O', 'INTC.O', 'AMZN.O', 'GS.N',' SPY', '.SPX', '.VIX', 'EUR=', 'JPY=', 'GDX', 'GLD']

s = '2010-01-01'
e = '2020-10-1'
inv = 'daily'
data1 = pd.DataFrame()
for i in instruments:
    df1 = ek.get_timeseries(i,  # RICs
              fields=['CLOSE'],  # fields to be retrieved
              start_date=s,  # start time
              end_date=e,  # end time
              interval=inv)
    df1.rename(columns = {'CLOSE': i}, inplace = True)
    if len(data1):
        data1 = pd.concat([data1, df1], axis=1)
    else:
        data1 = df1

data1

I hope this can help.
