Benzinga News Feed

Introduction

The Benzinga News Feed dataset by Benzinga tracks US Equity news releases. The data covers about 1,250 articles per day across 8,000 Equities, starts in January 2016, and is delivered on a second frequency. This dataset is created by structuring the content produced by Benzinga's editorial team.

This dataset depends on the US Equity Security Master dataset because the US Equity Security Master dataset contains information on splits, dividends, and symbol changes.

For more information about the Benzinga News Feed dataset, including CLI commands and pricing, see the dataset listing.

About the Provider

Getting Started

The following snippet demonstrates how to request data from the Benzinga News Feed dataset:

self.symbol = self.AddEquity("AAPL", Resolution.Daily).Symbol
self.dataset_symbol = self.AddData(BenzingaNews, self.symbol).Symbol
_symbol = AddEquity("AAPL", Resolution.Daily).Symbol;
_datasetSymbol = AddData<BenzingaNews>(_symbol).Symbol;

Data Point Attributes

The Benzinga News Feed dataset provides BenzingaNews objects, which have the following attributes:

Requesting Data

To add Benzinga News Feed data to your algorithm, call the AddData method. Save a reference to the dataset Symbol so you can access the data later in your algorithm.

class BenzingaNewsDataAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.SetStartDate(2021, 1, 1)
        self.SetEndDate(2021, 6, 1)
        self.SetCash(100000)
        
        self.symbol = self.AddEquity("AAPL", Resolution.Minute).Symbol
        self.dataset_symbol = self.AddData(BenzingaNews, self.symbol).Symbol
namespace QuantConnect.Algorithm.CSharp.AltData
{
    public class BenzingaNewsDataAlgorithm : QCAlgorithm
    {
        private Symbol _symbol, _datasetSymbol;
        
        public override void Initialize()
        {
            SetStartDate(2021, 1, 1);
            SetEndDate(2021, 6, 1);
            SetCash(100000);
            
            _symbol = AddEquity("AAPL", Resolution.Minute).Symbol;
            _datasetSymbol = AddData<BenzingaNews>(_symbol).Symbol;
        }
    }
}

Accessing Data

To get the current Benzinga News Feed data, index the current Slice with the dataset Symbol. Slice objects deliver unique events to your algorithm as they happen, but the Slice may not contain data for your dataset at every time step. To avoid issues, check if the Slice contains the data you want before you index it.

def OnData(self, slice: Slice) -> None:
    if slice.ContainsKey(self.dataset_symbol):
        article = slice[self.dataset_symbol]
        self.Log(f"{self.dataset_symbol} title at {slice.Time}: {article.Title}")
public override void OnData(Slice slice)
{
    if (slice.ContainsKey(_datasetSymbol))
    {
        var article = slice[_datasetSymbol];
        Log($"{_datasetSymbol} title at {slice.Time}: {article.Mentions}");
    }
}

To iterate through all of the dataset objects in the current Slice, call the Get method.

def OnData(self, slice: Slice) -> None:
    for dataset_symbol, article in slice.Get(BenzingaNews).items():
        self.Log(f"{dataset_symbol} title at {slice.Time}: {article.Title}")
public override void OnData(Slice slice)
{
    foreach (var kvp in slice.Get<BenzingaNews>())
    {
        var datasetSymbol = kvp.Key;
        var article = kvp.Value;
        Log($"{datasetSymbol} title at {slice.Time}: {article.Title}");
    }
}

Historical Data

To get historical Benzinga News Feed data, call the History method with the dataset Symbol. If there is no data in the period you request, the history result is empty.

# DataFrame
history_df = self.History(self.dataset_symbol, 100, Resolution.Daily)

# Dataset objects
history_bars = self.History[BenzingaNews](self.dataset_symbol, 100, Resolution.Daily)
var history = History<BenzingaNews>(_datasetSymbol, 100, Resolution.Daily);

For more information about historical data, see History Requests.

Remove Subscriptions

To remove a subscription, call the RemoveSecurity method.

self.RemoveSecurity(self.dataset_symbol)
RemoveSecurity(_datasetSymbol);

If you subscribe to Benzinga News Feed data for assets in a dynamic universe, remove the dataset subscription when the asset leaves your universe. To view a common design pattern, see Track Security Changes.

Example Applications

The Benzinga News Feed enables you to accurately design strategies harnessing real-time news releases. Examples include the following strategies:
