True Beats


The True Beats dataset by ExtractAlpha provides quantitative predictions of EPS and Revenues for US Equities. The data covers a dynamic universe of around 4,000-5,000 US-listed Equities on a daily average. The data starts in January 2000 and is delivered on a daily frequency. This dataset is created by incorporating the opinions of expert analysts, historical earnings, revenue trends for the company and its peers, and metrics on company earnings management.

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 True Beats dataset, including CLI commands and pricing, see the dataset listing.

About the Provider

ExtractAlpha was founded by Vinesh Jha in 2013 with the goal of providing alternative data for investors. ExtractAlpha's rigorously researched data sets and quantitative stock selection models leverage unique sources and analytical techniques, allowing users to gain an investment edge.

Getting Started

The following snippet demonstrates how to request data from the True Beats dataset:

from QuantConnect.DataSource import *

self.symbol = self.AddEquity("AAPL", Resolution.Daily).Symbol
self.dataset_symbol = self.AddData(ExtractAlphaTrueBeats, self.symbol).Symbol
using QuantConnect.DataSource;

_symbol = AddEquity("AAPL", Resolution.Daily).Symbol;
_datasetSymbol = AddData<ExtractAlphaTrueBeats>(_symbol).Symbol;

Requesting Data

To add True Beats 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 ExtractAlphaTrueBeatsDataAlgorithm(QCAlgorithm):

    def Initialize(self) -> None:
        self.SetStartDate(2019, 1, 1)
        self.SetEndDate(2020, 6, 1)

        self.symbol = self.AddEquity("AAPL", Resolution.Daily).Symbol
        self.dataset_symbol = self.AddData(ExtractAlphaTrueBeats, self.symbol).Symbol
namespace QuantConnect
    public class ExtractAlphaTrueBeatsDataAlgorithm: QCAlgorithm
        private Symbol _symbol, _datasetSymbol;

        public override void Initialize()
            SetStartDate(2019, 1, 1);
            SetEndDate(2020, 6, 1);

            _symbol = AddEquity("AAPL", Resolution.Daily).Symbol;
            _datasetSymbol = AddData<ExtractAlphaTrueBeats>(_symbol).Symbol;

Accessing Data

To get the current True Beats 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):
        data_point = slice[self.dataset_symbol]
        self.Log(f"{self.dataset_symbol} True beat at {slice.Time}: {data_point.TrueBeat}")
public override void OnData(Slice slice)
    if (slice.ContainsKey(_datasetSymbol))
        var dataPoint = slice[_datasetSymbol];
        Log($"{_datasetSymbol} True beat at {slice.Time}: {dataPoint.TrueBeat}");

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, data_point in slice.Get(ExtractAlphaTrueBeats).items():
        self.Log(f"{dataset_symbol} True beat at {slice.Time}: {data_point.TrueBeat}")
public override void OnData(Slice slice)
    foreach (var kvp in slice.Get<ExtractAlphaTrueBeats>())
        var datasetSymbol = kvp.Key;
        var dataPoint = kvp.Value;
        Log($"{datasetSymbol} True beat at {slice.Time}: {dataPoint.TrueBeat}");

Historical Data

To get historical True Beats 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[ExtractAlphaTrueBeats](self.dataset_symbol, 100, Resolution.Daily)
var history = History<ExtractAlphaTrueBeats>(_datasetSymbol, 100, Resolution.Daily);

For more information about historical data, see History Requests.

Remove Subscriptions

To remove a subscription, call the RemoveSecurity method.


If you subscribe to True Beats 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 True Beats dataset enables you to predict EPS and revenue of US-listed Equities for trading. Examples include the following strategies:

  • Finding surprise in EPS or revenue for sentiment/arbitrage trading
  • Stock or sector selections based on EPS or revenue predictions
  • Calculate expected return by valuation models based on EPS or revenue predictions (e.g. Black-Litterman)
