The guy managed to go trough all these hard concepts without an explanation off what they mean, how they behave and their position in the package's structure. Kudos!

Excellent presentation keep making such good videos about dashboards in dash

Instead of iexfinance use yahoo, no token reqired:
1. Import datareader:
import pandas_datareader.data as web
2. instead of: df = get_historical_data('GE', start=start, end=end, output_format='pandas'),
Write: df = web.DataReader("GE", 'yahoo', start, end)

[rodionlim]

This should work as an alternative for those who are having troubles with iex:

import pandas_datareader as pdr
df = pdr.get_data_yahoo('GE', start, end)

[elvisleng]

Also, it took me a couple tries to realize that you need a token from IEX in order to access the information. You can register for free on IEX's website and then add the TOKEN to your environment variable as IEX_TOKEN=<your token>. Thank you for the video

[pedroramonalmeida]

How did you called get_historical_data without parsing the token argument?

[Nnxful]

I get the error:

Out of bounds nanosecond timestamp: 5-11-15 01:38:59


Code:

start = datetime.datetime.today() - relativedelta(year=5)
end = datetime.datetime.today()


How do I resolve this? I Cant find any proper answers.

Couldn't get it to work .. an API token is required and I didn't manage to configure it correctly.

[Runawaygeekchannel]

Seems you need an auth key now for IEX, they do a free one and to add it to the above it works here ( df = get_historical_data("GE", Token="YOURKEY", start-start, end-end, output_format="pandas")

[carstenbecker]

doesnt work for me. Error with Modul get_historical_data and this iexfinance modul is installed with pip in command prompt :-(((

[ryankao]

sadly today the iexfinance requires us to register account to get API token, tried but it was not friendly...

[jasoncprince]

I could not complete the tutorial.
Was able to pull the head info a few times and without changing anything started to get this error:
raise IEXQueryError("The query could not be completed. "
An error occurred while making the query.

[iliasschahly]

j'ai un problème au niveau de la bibliothèque iexfinance je trouve ce type de problème
Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools"

[Programme]

Hello, thank you for this tutorial :) What is the outro music ?

[rajtheo]

also @anna from iexfinance import get_historical_data has been deprecated. so we have to use .from iexfinance.stocks

In any event this is a very useful lesson. Thanks

[jasoncprince]

Was getting, TypeError: 'module' object is not callable, for my datetime.
Changed from, import datetime as datetime
Changed to, from datetime import datetime
Issue resolved.

Not a good level of understanding here.
