Expected behavior

Actual behavior

It appears that some endpoints (such as get_earnings are returning incorrectly-formatted data)

from iexfinance import Stock

aapl = Stock("AAPL", output_format='pandas')
aapl.get_earnings()

#                                                                            AAPL
# earnings [{'fiscalPeriod': 'Q4 2017', 'announceTime': '...
# symbol                                                                     AAPL

This is incorrect. In addition, odd behavior is that get_earnings sometimes returns with a symbol index, and sometimes does not. This would cause calls like aapl.get_earnings()["totalDebt"] to fail.

Date/time of issue

Expected behavior

It should handle empty state for finances more gracefully and return an empty dictionary

Actual behavior

On bulk entry for get_financials(), it breaks and shows the KeyError exception

IEX now supports cryptocurrency quotes for a limited number of symbols.

Expected behavior

Actual behavior

Currently only JSON is supported. Changing outputFormat to pandas does not do anything.

Very minor and quick fix, but in __init__.py, Stock() throws a ValueError when a lot size of 100 is used, even though the API is capable of handling it. I've made this change myself on a forked version and can confirm that it works.

Line 40:
elif isinstance(symbols, list) and 0 < len(symbols) < 100:
should be:
elif isinstance(symbols, list) and 0 < len(symbols) <= 100:

self = <tests.test_stock.TestHistorical object at 0x7fda905e40f0>

def test_single_historical_json(self):

    f = get_historical_data("AAPL", self.good_start, self.good_end)
    assert isinstance(f, dict)
    assert len(f["AAPL"]) == 73

    expected1 = f["AAPL"]["2017-02-09"]

  assert expected1["close"] == 132.42

E assert 130.3577 == 132.42

I was making sure I had everything installed properly, but ran into this test failure. As I started to chase down the fail, I get another fail as the historical high seems to be different. I was ok with the close, as it could be adjusted close, but when high was different, I started to question what it 'should' be.

Hi there,

Can you please change the batch request to not request 10 different api endpoints by default and instead make the user specify which requests they are making?

We are seeing lots of users leave the defaults and add thousands of symbols which isnt ideal from our end. In addition, many of the endpoints being requested return duplicate data that is returned in other ones in the same request. Thanks.

Summary (include Python version)

Python 3.6.4

Date/time of issue

25th September 2018

Expected behavior

to get empty dictionary or empty dataframe

Actual behavior

When calling get_historical_data for symbol 'ZNWAA' I get an keyerror 'date'. This happens on setting index od 'Date'. As long as IEX do not provide any data for this symbol the index can not be set on empty dataframe.

IEX made major updates to v1.0 of their api on 1/30/2018, per its CHANGELOG. Would like to add integration to most of these features for RLS 0.3.0 of iexfinance. Thinking of pushing back RLS 0.3.0 to integrate all features cleanly.

Stock

Add endpoints

• OHLC
  - [ ] IEX Short Interest List
  - [ ] IEX Regulation SHO Threshold Securities List
• Time Series

Update Chart endpoint and historical data

• Add chartReset, chartSimplify, and chartInterval parameters

Reference Data

Add endpoints

• IEX Corporate Actions
• IEX Dividends
• IEX Next Day Ex Date
• IEX Listed Symbol Directory

IEX Market Data

- [ ] Add sector and securityType to TOPS

Is get_dividends not implemented yet ? Python 3

Date/time of issue

09/19/2018 12:57 pm

Expected behavior

Docs says get_dividends is a top level function that can be used

Actual behavior

When I add "from iexfinance import get_dividends as div" to a script , I get an error:
ImportError: cannot import name 'get_dividends'

RLS 0.3.0 adds codecov support for code coverage.

As of now codecov does not automatically upload coverage reports when commits are made

TODO

• Repair .travis.yml configuration
• Verify code coverage

Per the docs, the chart endpoint parameter values also include:

date: IEX-only data by minute for a specified date in the format YYYYMMDD if available

The following script

from iexfinance import IexFinance as iex

aapl = iex("AAPL", chartRange="date")

aapl.get_chart()

returns:

[]

when it should return IEX's intra-day prices from a specified date.

A few things need to be cleaned up involving iexfinance's setup as a package.

Docstrings

• Clean and verify all necessary docstrings

Docs

• Create CONTRIBUTING section of readme and docs
  • Repair flake8 requirements
• Test and verify all hyperlinks and images in docs

Github

• Create issue template
• Create pull request template

Summary (include Python version)

python 3.6.4
stock.StockReader.get_time_series returns '1m' lookback date regardless of lookback parameter passed (e. g. pass '6m' still returns '1m' data

Date/time of issue

2018/11/03

Expected behavior

data from 2018/06/03 to 2018/11/03 returned

Actual behavior

data from 2018/10/03 to 2018/11/03 returned

get_market_tops and get_market_last should restrict their results to a single symbol or list of symbols if they are passed, else return data for all listed symbols. Thus we would expect:

from iexfinance import get_market_tops
len(get_market_tops("AAPL"))

to be 1. But as of now both this function and get_market_last return the entire list (~8600 tickers) each time.

Currently in setup.py:

 'Programming Language :: Python',
 'Programming Language :: Python :: 2',
 'Programming Language :: Python :: 2.6',
 'Programming Language :: Python :: 2.7',
 'Programming Language :: Python :: 3',
 'Programming Language :: Python :: 3.3',
 'Programming Language :: Python :: 3.4',
 'Programming Language :: Python :: 3.5',

Travis only runs tests for Python 3.5, per travis.yml

TODO*

• Update TravisCI to test all listed compatible Python versions
  • If problems arise with tests, patch compatibility issues if able, else remove version from compat list

In similar style to Pandas Datareader's _sanitize_dates, we should probably have the date period for functions such as get_historical_data and get_stats_daily default to somthing like 1/1/2015 for start and today for end. This would allow null start and end parameters to make valid requests for those methods...docs will also need to indicate the same.

Still thinking about this.

Hello,

I'm having trouble getting this to work all of a sudden. I was testing some of the code last night and it was working perfectly fine, but now I get the following traceback. I have included a sample of the code I'm using.

The traceback led me to this part in iexretriever.py:

    def _validate_response(response):
        if response.text == "Unknown symbol":
            raise IEXSymbolError(self.symbolList[0])

        json_response = response.json()
        if not json_response:
            raise IEXQueryError()
        elif "Error Message" in json_response:
            raise IEXQueryError()
        return json_response

When I had the response.text printed to console it said:

"Maximum of 10 types allowed." Hopefully, that helps. I have no idea what that means.

Code sample:

import iexfinance as iex
batch = ['AAPL', 'GOOGL', 'TSLA']
for symbol in batch:
    print(iex.Share(symbol))
print(iex.Batch(batch))

The following request will fail:

from iexfinance imort Stock

aig = Stock("aig+")

# iexfinance.utils.exceptions.IEXSymbolError: Symbol AIG+ not found.

per the IEX docs:

Be sure to url-encode the values you pass to your parameter.
(i.e. ?symbols=AIG+ encoded is ?symbols=AIG%2b.)

since we are not doing so now, we are essentially passing:

symbols=AIG+

which will not work. Need to url-encode all symbol names to force percent-encodings of non-alphanum characters.

Consider the following get_open result

{"open":{"price":178,"time":1520346600658},"close":{"price":176.67,"time":1520370000495},"high":178.25,"low":176.13}

price will be cast as an int at some point. this should remain a float (and possibly display 178.00). Returning an int is incorrect behavior.

Does this module aim to create a way to make multiprocessing easier? If somebody is trying to run get_historical_data() on thousands of tickers, this would save a lot of time (if you are running four or eight processes at once, that could take time down from 30 seconds to 5 seconds).

Below, I've attached some code that I've made for receiving requests from IEX, but it is not nearly as clean as the format given by the iexfinance module:

import os
import multiprocessing
import requests
iex_url_base = "https://api.iextrading.com/1.0"


def batch_get(batch, url_end):
    """
    Note: This function is only intended to be used for get_pool_response() function in start module,
    but SHOULD NOT be embedded into get_pool_response to avoid pickling problems.
    :param batch: Give a single batch of tickers (ex: 'A,AA,AAPL,...,MSFT')
    :param url_end: Add the query that you will be using  (ex: "&types=dividends&range=5y")
    :return: all the data necessary to make multiple get requests at once
    """
    batch_url = f"{iex_url_base}stock/market/batch?symbols={batch}{url_end}"
    response = requests.get(batch_url).json()
    return response


def get_pool_response(batch_data, url_end, num_processes=os.cpu_count()):

    """
    :param batch_data: List of concatenated symbols -- use get_symbols() and set_batches()
    functions to set batch_data
    :param url_end: Add the query that you will be using  (ex: "&types=dividends&range=5y")
    :param num_processes: Defaults to # of computer cores, but it is possible to have more.
    Increase this as your computer capacity allows for faster multiprocessing.
    :return: Returns all batch GET requests from API for given url_end.
    """
    pool = multiprocessing.Pool(processes=num_processes)
    outputs = []
    outputs.append(pool.starmap(batch_get, [[batch, url_end] for batch in batch_data]))
    pool.close()
    pool.join()
    return outputs

I keep getting a TimeoutError for everything I try. Not entirely sure what I'm doing wrong here. The code for this has worked sporadically before but it all seems very intermittent.

from iexfinance import Stock
s = Stock("AAPL")
print(s.get_book())

Migration from .md/mkdocs to .rst/sphinx has left some hyperlinks broken.

TODO

• Verify all hyperlinks when docs structure completed.

Installed the package using

pip install iexfinance

When I try to import the package, in Python 3.6

from iexfinance import Stock

I get the error

ImportError: cannot import name 'Stock'

Did I miss out something?

There is a function to pull out current debt but not current liabilities. Current liabilities is a more useful feature for finance people to calculate current ratio.

Please consider adding it in.

Thanks,
Fabelsady

Pandas dataframe output, specifically the index.

This call returns a dataframe with the date as an 'Index'

In [20]: df = get_historical_data(stock_symbol, start=start, end=end, output_format='pandas')

In [21]: df.info()
<class 'pandas.core.frame.DataFrame'>
Index: 73 entries, 2017-02-09 to 2017-05-24
Data columns (total 5 columns):
open      73 non-null float64
high      73 non-null float64
low       73 non-null float64
close     73 non-null float64
volume    73 non-null int64
dtypes: float64(4), int64(1)
memory usage: 3.4+ KB

I believe the more proper thing to do is return the date as a DatetimeIndex, which means that plotting, sampling, interpolation, etc... all 'do the right thing'

In [22]: df.index = pandas.to_datetime(df.index)

It seems that the Sphinx iPython for the docs is not loading correctly.

Hi,
First of all, thank you for hard work.
I have a quick question.
Is there any method to get list(gainers, losers, etc)? I couldn't find it.
( IEX document link is https://iextrading.com/developer/docs/#list )
Please let me know.

Summary (include Python version)

I am using the library to develop a component for Home Assistant. When I try to fetch a quote with get_quote() for a non-existing symbol (for example 'AAA'), an error is raised (see below). A try/except does not catch this.

Date/time of issue

Expected behavior

sample code:

        from iexfinance import Stock
        symbol = 'AAA'
        stock = Stock(symbol)
        try:
            quote = stock.get_quote()
            _LOGGER.debug("Received new values for symbol %s", symbol)
        except ValueError as error:
            _LOGGER.error(
                "Unknown symbol '%s'", self._symbol)

Thanks Aaron Gonzalez for reporting this issue. Seems to only effect Python 2 via pip install.

Per documentation, batch requests include "Comma delimited list of symbols limited to 100.". Currently accepting only 50.

Wrapper does not conform to PEP8 styling

0.3.0 will be the first official release of iexfinance. Changes are currently being merged into the master branch with a projected release date of 2/5/2018.

Python 2.7+ install errors (#44), test case failures (#45), and errors with the IEX Market Data Functions (#46) will trigger a new minor release 0.3.2

Default options

aapl = iex("AAPL")
aapl.get_chart()
