Description

A simple Python API for Investopedia's stock simulator games.

Features

Currently you can programmatically:

  • Read all positions in your stock, and short portfolios and get quotes for each position
  • Fetch and cancel pending/open trades
  • Buy/Sell long positions
  • Short sell/cover short positions
  • Buy/sell options
  • Perform option chain lookups
  • Buy/sell options

Dependencies

To use this API, there are a few dependencies that you will need to install. See the below sections for an explanation of each.

Python

This API is intended to be used for writing Python programs to automate trades in the Investopedia Stock Simulator, therefore you should have Python installed on your system. I recommend using Python 3.12.2 or later to avoid running into issues or other problems. You can download Python here.

Git (optional)

This API is not currently hosted as a package anywhere, so you'll need to download the code directly from GitHub to use it. Download and install the latest version of Git on your system and run the following in a terminal to download a copy of this repository:

git clone https://github.com/dchrostowski/investopedia_simulator_api.git/

Alternatively, you can just download a zipped archive of the source code directly from this project's GitHub page and unzip it somewhere on your filesystem. To do this, click on the green Code button and select Download ZIP.

Node.js

Node.js is utilized to facilitate logging in to the simulator with a virtual web browser and fetching authentication tokens. Download and install the latest version of Node.js on your system here..

Usage

Once all dependencies are installed, you will need to use pip to install supplementary Python packages to run your code with the API. Open a terminal on your system and navigate to where you downloaded this code:

cd path/to/investopedia_simulator_api

Next run the following command to install the supplementary packages:

pip install -r ./requirements.txt

Once all the required packages are installed, you will need to provide your login credentials for the Investopedia Stock Simulator. Rename the credentials_example.json file to credentials.json, open it, and replace the username and password values with your actual username and password for logging in to Investopedia. Make sure you leave the double quotes intaact.

Finally, try running the provided example.py file. This example.py file is a usage example of the API. Feel free to modify it as you see fit for your needs:

python example.py
