How to Retrieve CBOE Vix Volatility OHLC Data for Developing Trading Algorithms with Indices-API

Introduction

In the world of trading, having access to accurate and timely data is crucial for developing effective trading algorithms. One of the most sought-after data points is the Open, High, Low, Close (OHLC) data for various indices, particularly the CBOE Vix Volatility Index (VVIX). This blog post will guide you through the process of retrieving OHLC data using the Indices-API, providing you with the necessary tools to enhance your trading strategies.

About CBOE Vix Volatility (VVIX)

Retrieving OHLC Data

To retrieve OHLC data for the CBOE Vix Volatility Index (VVIX), you will use the Open/High/Low/Close price endpoint. This endpoint allows you to query the API for the open, high, low, and close prices for a specific date or date range.

Sample Request

To make a request for OHLC data, you will need to format your API call as follows:

GET https://api.indices-api.com/open-high-low-close/{date}?access_key=YOUR_API_KEY&symbol=VVIX

In this request, replace {date} with the desired date in the format YYYY-MM-DD and YOUR_API_KEY with your actual API key.

Sample Response

Upon a successful request, you will receive a JSON response containing the OHLC data. Here is an example response:

{
"success": true,
"timestamp": 1766798173,
"base": "USD",
"date": "2025-12-27",
"rates": {
"VVIX": {
"open": 0.00028,
"high": 0.00029,
"low": 0.00027,
"close": 0.00029
}
},
"unit": "per index"
}

This response provides the open, high, low, and close prices for the VVIX on the specified date, allowing you to analyze market movements effectively.
