# StockCharts Add-Ons

Add-ons extend the functionality of your StockCharts membership, allowing you to add specialized tools and other features to your account. Please see the StockCharts Marketplace for a complete list of add-ons that are currently available and a sneak peek at new add-ons coming soon.

Some of our add-ons are one-time purchases and some are subscription-based, requiring renewal each year to maintain access to the tools. Please see the [StockCharts Marketplace](https://stockcharts.com/marketplace/) for purchasing details for specific add-ons.

## Installing StockCharts Add-Ons

To add a StockCharts Add-On, visit the Marketplace and choose the add-on you want to purchase. Click the green Buy Now (or Subscribe Now for subscription-based add-ons) button, then install.

A popup window will open, summarizing the payment and billing info for the plug-in. Click the "Confirm and Submit" button to finalize the purchase. Your new add-on functionality will be available immediately afterwards.

You can request a full refund for a StockCharts add-on within the first 10 days of your initial purchase. **After 10 days, the add-ons are no longer refundable.**

{% hint style="warning" %}
Make sure you are logged into your StockCharts account before making a Marketplace purchase. This ensures the add-on is installed on your account.
