About 3 minutes 2 steps Checked October 2026

Before you start

  • An email address

Create your Nasdaq Data Link API key

  1. 1

    Sign up

    Create an account at data.nasdaq.com.

  2. 2

    Copy the key

    Open Account settings and copy the API key. Save it as NASDAQ_DATA_LINK_API_KEY.

Test the key

Before wiring the key into a strategy, make one request by hand. It separates “the key is wrong” from “my code is wrong”.

curl -s "https://data.nasdaq.com/api/v3/datatables/NDAQ/USEDHOL.json?api_key=$NASDAQ_DATA_LINK_API_KEY&qopts.per_page=1"
A datatable object means the key works; product codes vary by subscription.

Add the key to your AlgoGP project

  1. 1

    Open your project’s APIs & keys tab

    Open the strategy project and select APIs & keys in the workspace tabs.

  2. 2

    Paste each value

    Paste the values into NASDAQ_DATA_LINK_API_KEY and click Save. Values are encrypted at rest, never shown again and never written into code or exports.

  3. 3

    Run locally with the same names

    Exported projects read the same names from .env (copy .env.example). Keep .env out of version control.

NASDAQ_DATA_LINK_API_KEY=paste-your-value-here
.env for local runs

Add Nasdaq Data Link signals to a strategy

Combine price rules with news and sentiment filters, test them point-in-time so nothing leaks from the future, and export the code.

  • Sentiment filters that block entries on bad news
  • Point-in-time replay in every backtest
  • Exported Python reads the same feed live
