Data Providers

IEX Cloud

Introduction

Instead of using the live data from your brokerage, you can also use IEX Cloud. This tutorial demonstrates how to set up the IEX Cloud data provider with the QuantConnect Paper Trading brokerage.

To use IEX Cloud, you need an account subscribed to one or more data bundles. You also must select either the Launch, Grow, or Enterprise subscription tier; this dictates your maximum requests per second. If you don't have an account, register today and get your API key. Pricing information can be found here.

Upon registration, your account will automatically start a 7-day free trial. This trial has access to all API endpoints and a rate limit of 5 requests per second. If you have any questions regarding IEX Cloud's API service, please contact them here: support@iexcloud.io.

To view the implementation of the IEX Cloud integration, see the Lean.DataSource.IEX repository.
