Price Data

Price data is provided in multiple formats: NumPy recarray, NumPy ndarray or Pandas DataFrame. This is determined through the format parameter. If not specified, the default is NumPy recarray.

Dates are determined by passing in any (or none) of the following named parameters:

# start_date and end_date can be provided as a string (YYYY-MM-DD or YYYYMMDD format), 
# datetime, Pandas Timestamp, or NumPy datetime64.  All types work!
start_date = '1990-01-01'   
end_date = '2000-01-01'   # If not specified, the end date is today
limit = 50  # This provides the last X records
interval = 'D' # D=Daily, W=Weekly, M=Monthly - the date given is the last date of the interval 

Price & Volume adjustment allows you to adjust historical stock prices and volumes to account for the effect of capital events and dividends.

priceadjust = norgatedata.StockPriceAdjustmentType.NONE
priceadjust = norgatedata.StockPriceAdjustmentType.CAPITAL
priceadjust = norgatedata.StockPriceAdjustmentType.CAPITALSPECIAL
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN # Default

Date padding allows you to repeat the prior close on days where no price record would otherwise exist.

padding_setting = norgatedata.PaddingType.NONE  # Default
padding_setting = norgatedata.PaddingType.ALLMARKETDAYS
padding_setting = norgatedata.PaddingType.ALLWEEKDAYS
padding_setting = norgatedata.PaddingType.ALLCALENDARDAYS

Columns returned include Date, Open, High, Low, and Close. For certain instruments, additional columns are provided where applicable including: Volume (Stocks, some Indices, some Indicators, Futures), Turnover (Stocks, some Indices, some Indicators), Unadjusted Close (Stocks), Dividend (Stocks), Open Interest (Futures, ASX Exchange Traded Options), Delivery Month (Continuous Futures).

Examples

import norgatedata
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN 
padding_setting = norgatedata.PaddingType.NONE   
symbol = 'AAPL'
start_date = '1990-01-01'
timeseriesformat = 'numpy-recarray'

# Provides data on GOOG from 1990 until today in 
# a NumPy recarray format, with explicitly set stock price 
# adjustment and padding settings
pricedata_recarray = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    start_date = start_date,
    timeseriesformat=timeseriesformat,
)

# Now in a Pandas-compatible format
import pandas as pd
timeseriesformat = 'pandas-dataframe'
start_date = pd.Timestamp('1900-01-01') # we can also provide dates as a Pandas Timestamp
pricedata_dataframe = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    start_date = start_date,
    timeseriesformat=timeseriesformat,
)

# Weekly data instead
timeseriesformat = 'pandas-dataframe'
start_date = pd.Timestamp('1900-01-01') # we can also provide dates as a Pandas Timestamp
pricedata_dataframe = norgatedata.price_timeseries(
    symbol,

    interval='W'
)

# Now in a Numpy Ndarray
import numpy as np
timeseriesformat = 'numpy-ndarray'
start_date = np.datetime64('1900-01-01') # we can also provide dates as a Numpy datetime64
pricedata_ndarray = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    start_date = start_date,
    timeseriesformat=timeseriesformat,
)

# Now limiting results to final 500 bars
pricedata_dataframe = norgatedata.price_timeseries(

    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    limit=500,
    timeseriesformat=timeseriesformat,
)

# Now limiting results to a specific date range
end_date='1999-12-31'

    padding_setting = padding_setting,
    start_date = start_date,
    end_date = end_date,
    timeseriesformat=timeseriesformat,
)

# Now using a numerical unchanging assetid instead of a symbol
timeseriesformat = 'pandas-dataframe'
assetid = 136817
pricedata_dataframe = norgatedata.price_timeseries(
    assetid,
    limit=500,
    timeseriesformat=timeseriesformat,
)

Datetime formats

By default, NumPy ndarray and recarray provides datetime64 formattted as '<M8[D]' (daily dates) as timezone naive. Pandas dataframes default to use datetime64 formattted as '[ns]' to match Pandas Timestamp, as timezone naive.

These can be altered with the following parameters:

datetimeformat='<desired format>'

allowed values are:

• 'datetime' : Provides Python datetime.datetime objects
• 'date' : Provides Python datetime.date objects
• 'datetime64ns': Provides timezone-naive NumPy datetime64 in 'datetime64[ns]' format
• 'datetime64ms': Provides timezone-naive NumPy 'datetime64[ms]' format
• 'm8d': Provides timezone-naive NumPy datetime64 in '<M8[D]' format

timezone='<desired timezone>'

This will allocate the dates into the timezone as shown on any of the time series functions. Times will still be shown as 00:00:00. Accepts a string with valid timezones such as 'UTC', 'US/Eastern' etc.

Dividend Notes

Dividends shown in the price_timeseries Dividend column depending on whether or not they have already been accounted for in the data by the "Price Adjustment" method.

• If the data is adjusted for capital reconstructions only, then the sum of both special and ordinary dividends for that day are shown.
• If the data is adjusted for capital reconstructions and special dividends, then only the sum of ordinary dividends for that day are shown.
• If the data is adjusted for capital reconstructions, special dividends and ordinary dividends, then no information is shown.

Dividend/Distribution information is shown as of the day before the ex-date - i.e. if you are holding the security at the close, you will be entitled to the dividend/distribution.

Time Series Data

Index Constituents

To determine whether a stock was an index constituent on a particular date, you can use the index constituent timeseries function. You can also pass in an existing NumPy ndarray or Pandas Dataframe and a new column will be added and returned

symbol = 'AAPL'
indexname = 'Russell 3000'
indexname = 'S&P 500'  # Can also be an index symbol, such as $SPX, $RUI etc.

idx = norgatedata.index_constituent_timeseries(
    symbol,
    indexname,
    timeseriesformat = "numpy-recarray",
)

idx = norgatedata.index_constituent_timeseries(
    symbol,
    indexname,
    padding_setting = padding_setting,
    start_date = start_date,
    limit = -1,
    timeseriesformat  = "numpy-ndarray",
)

idx = norgatedata.index_constituent_timeseries(
    symbol,
    indexname,
    padding_setting = padding_setting,
    start_date = start_date,
    limit = -1,
    timeseriesformat  = "pandas-dataframe",
)

# Let's pass in data from a recarray for TWTR

import norgatedata
import pandas as pd
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN
padding_setting = norgatedata.PaddingType.NONE
symbol='TWTR'
timeseriesformat = 'numpy-recarray'
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN
padding_setting = norgatedata.PaddingType.NONE
pricedata_recarray = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    timeseriesformat = timeseriesformat,
)

# and now make the call to index_constituent_timeseries
pricedata_recarray2 = norgatedata.index_constituent_timeseries(
    symbol,
    indexname,
    padding_setting = padding_setting,
    limit = -1,
    numpy_recarray = pricedata_recarray,
    timeseriesformat = timeseriesformat,
)

# Alternative using pandas dataframes instead:

import norgatedata
import pandas as pd
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN
padding_setting = norgatedata.PaddingType.NONE
symbol='TWTR'
timeseriesformat = 'pandas-dataframe'
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN
padding_setting = norgatedata.PaddingType.NONE
pricedata_df = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    timeseriesformat = timeseriesformat,
)

# and now make the call to index_constituent_timeseries
pricedata_df2 = norgatedata.index_constituent_timeseries(
    symbol,
    indexname,
    padding_setting = padding_setting,
    limit = -1,
    pandas_dataframe = pricedata_df,
    timeseriesformat = timeseriesformat,
)

Major Exchange Listed

majexch = norgatedata.major_exchange_listed_timeseries(
    symbol,
    timeseriesformat = "numpy-recarray")

Provides indication about US stocks on whether they are listed on a major exchange (e.g. NYSE, Nasdaq, NYSE American, NYSE Arca, Cboe BZX, IEX) (value = 1) or as an OTC/Pink Sheet stock (value = 0) for each trading date is available for all Equities and ETPs.

Note: Data is only available for this item from 2000 onwards.

Capital Event

capevent = norgatedata.capital_event_timeseries(
    symbol,
    timeseriesformat = "numpy-recarray")

This indicator will show when a capital event occurred. Effective on holding the security at the close on the day prior to the ex-date. Events include splits, reverse splits, bonus issues, stock dividends (dividends paid as stock) and complex reorganizations of capital (value = 1, otherwise if there is no event, value = 0)

Dividend Yield

divyield = norgatedata.dividend_yield_timeseries(
    symbol,
    timeseriesformat = "numpy-recarray",
)

This indicator uses a trailing 12 month sum of all split-adjusted ordinary dividends and is calculated daily against the close price. New dividends are incorporated on the entitlement date (the trading day prior to the ex-dividend date) after which the trailing 12 month sum of dividends is recalculated. Special dividends, distributions and spin-offs are not included. The lookback period is adaptive to take into account slight variations in ex-dividend dates from year-to-year.

Padding Status

paddingstatus = norgatedata.padding_status_timeseries(
    symbol,
    timeseriesformat = "numpy-recarray",
)

This indicator will show when a price record has been padded in accordance with the Date Padding setting. If the Date Padding is set to "No padding" then this indicator will not return any values.

Unadjusted Close

This is not normally needed, as Unadjusted Close is provided in the price timeseries.
It is provided here to be used as a helper routine for other Python libraries such as zipline-norgatedata.

unadjclose = norgatedata.unadjusted_close_timeseries(
    symbol,
    timeseriesformat = "numpy-recarray",
)

Security lists

Watchlists

Python can retrieve the contents of any watchlist that exists in NDU's WatchList Library

When you create a watchlist, you can make it as broad or narrow as you like. To have a dynamic watchlist for the entire "Stock Market", don't apply any filters.

The symbols of a watchlist can be retrieved into a Python list using the watchlist_symbols() and watchlist() functions.

Watchlist Symbols

watchlistname = 'S&P 500'
symbols = norgatedata.watchlist_symbols(watchlistname)

watchlistname = 'Russell 3000 Current & Past'
symbols = norgatedata.watchlist_symbols(watchlistname)

Watchlist Securities

If you want the symbol, assetid and name of each security, use the watchlist function

watchlistname = 'Russell 3000 Current & Past'
wlcontents = norgatedata.watchlist(watchlistname)

Available Watchlists

To retrieve the names of all of the watchlists within Norgate Data's watchlist library, use the watchlists() function

allwatchlistnames = norgatedata.watchlists()

Databases

Python can retrieve the contents of any database available in a subscription. You can see which databases are available by opening NDU and clicking on the "Database" tab.

As an example, a subscriber to US Stocks at the Platinum level should see the following databases in the "Database List": 'US Equities', 'US Equities Delisted', 'US Indices', 'World Indices','Economic', 'Forex Spot', and 'Futures Continuous'.

Database Symbols

databasename = 'US Equities'
symbols = norgatedata.database_symbols(databasename)

databasename = 'World Indices'
symbols = norgatedata.database_symbols(databasename)

Database Securities

If you want the symbol, assetid and name of each security provided, use the database function:

databasename = 'AU Equities'
databasecontents = norgatedata.database(databasename)

Available Databases

To retrieve the names of all available databases, use the databases() function.

alldatabasenames = norgatedata.databases()

Futures Symbols

See Futures Market Symbols and Futures Market Session Symbols above.

---

Other informational functions

• norgatedata.last_database_update_time(database) - returns a datetime object when information was updated for a given database, where database is the shortened form for each database. Database names include au, aueto, auwarrant, auindex, ca, caindex, us, usindex, cashcommodity, economic, future, forex, contfuture, worldindex

• norgatedata.last_price_update_time(symbol) datetime when price was last updated for the given symbol

• norgatedata.status() - shows whether NDU is running (returns True if running, or False if not)

---

Additional notes

Accessing data by assetid instead of symbol

Instead of using a security's symbol, you can obtain its unique Norgate-provided identity known as assetid. This is an unchanging number and is therefore useful when storing positions/orders into data files where the symbol may change in the future.

All of the calls above that reference 'symbol' (as a string) can also take an assetid (as an integer). For example, symbol MSFT = assetid 134016. symbol AMZN = assetid 129769.

Error Handling

If an invalid symbol or invalid parameters are specified, then the ValueError exception will be raised.

The logger module will also output human-interpretable detail relating to the error.

If there is no data available (for example, a informational or fundamental field that is not reported for that company), then None is returned, except in the case where multiple values are expected eg. (None, None).

Multithreading / Multiprocessing compatibility

The norgatedata package is compatible with multithreading and multiprocessing libraries/packages, to take advantage of multiple CPU cores. This can result in a significant reduction in runtime by running operations in parallel, depending upon workload.

Python Quant/Backtesting Package Integration

All of the routines developed in this module provide the data that can be used for backtesting/scanning of data. There are many backtesting packages developed that use Python. In this section, we provide more information about how to use with popular backtesting python packages with sample code and/or links to Norgate-developed integration packages.

Zipline

The package: zipline-norgatedata provides a tight integration between Zipline and Norgate Data

Key Features

• Survivorship bias-free bundles
• Incorporates time series data such as historical index membership and dividend yield into Zipline's Pipeline mechanism
• No modifications to the Zipline code base (except to fix problems with installation and obsolete calls that crash Zipline)
• Simple bundle creation
• Easy ingestion of equities data into Zipline with a simple list of symbols you want to incorporate and/or import your own symbol lists and/or use pre-built or user-created watchlists from Norgate Data
• Easy ingestion of futures data into Zipline with a simple list of symbols you want to incorporate, futures market sessions you want to incorporate, and/or use pre-built or user-created watchlists from Norgate Data

Backtrader

Backtrader is a Python framework for backtesting and trading.

To create a "data feed" of a given symbol:

import backtrader as bt
import norgatedata

# ... your code here ...
cerebro = bt.Cerebro()  # create a "Cerebro" engine instance
# ... your code here ...

# Obtain a Pandas dataframe for a given security from Norgate Data
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN 
padding_setting = norgatedata.PaddingType.NONE   
symbol = 'AAPL'
start_date = '2010-01-01'
timeseriesformat = 'pandas-dataframe'
pricedata_dataframe = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    start_date = start_date,
    timeseriesformat=timeseriesformat,
)

# Rename columns to suit Backtrader
pricedata_dataframe.rename(
    columns={ 'Open':'open',  'High':'high', 'Low':'low', 'Close':'close', 'Volume':'volume', 'Open Interest':'open interest'},
    inplace=True)

# Backtrader can convert this dataframe into its own internal format with:
data = bt.feeds.PandasData(dataname=pricedata_dataframe)
cerebro.adddata(data)  # Add the data feed
# ... your code here ...

pybacktest

pybacktest is a backesting package for simple backtests against a single security. It is no longer maintained by its author but it is still functional.

Pre-requisites:

• Python 3.5-3.9
• Git
• Virtual Environment (e.g. Anaconda)

Here's how we installed it:

Install the 64 bit MiniConda or Anaconda Distribution.

Install the 64 bit version of Git and used all default options at install time.

Start an Anaconda (base) prompt, create an environment and install the appropriate versions of packages as follows:

conda create -n pybacktest39 python=3.9
conda activate pybacktest39
pip install git+https://github.com/ematvey/pybacktest.git
pip install pandas_datareader
pip install norgatedata

Here's a sample piece of code that uses data from Norgate data.

import norgatedata
import pybacktest
import pandas

# Obtain data from Norgate Data first, in Pandas dataframe format
priceadjust = norgatedata.StockPriceAdjustmentType.TOTALRETURN 
padding_setting = norgatedata.PaddingType.NONE   
symbol = 'AAPL'
start_date = '2010-01-01'
timeseriesformat = 'pandas-dataframe'
ohlc = norgatedata.price_timeseries(
    symbol,
    stock_price_adjustment_setting = priceadjust,
    padding_setting = padding_setting,
    start_date = start_date,
    timeseriesformat=timeseriesformat,
)

# Change column names
ohlc.rename(
    columns={'Open':'O', 'High':'H', 'Low':'L', 'Close':'C', 'Volume':'V'},
    inplace=True)

# sample pybacktest code:
ms = ohlc.C.rolling(50).mean()
ml = ohlc.L.rolling(100).mean()
buy = cover = (ms > ml) & (ms.shift() < ml.shift())
sell = short = (ms < ml) & (ms.shift() > ml.shift())

backtestresults = pybacktest.Backtest(locals())
