Retrieving OHLC Data

To retrieve OHLC data for the Nasdaq Composite Index, you will use the Open/High/Low/Close (OHLC) Price Endpoint. This endpoint allows you to query the API for the open, high, low, and close prices for a specified date or date range. The data returned can be used for various analytical purposes, including technical analysis and trading strategy development.

Sample Request

To make a request for OHLC data, you would structure your API call as follows:

GET https://api.indices-api.com/open-high-low-close/NASDAQ/YYYY-MM-DD?access_key=YOUR_API_KEY

Replace YYYY-MM-DD with the desired date for which you want to retrieve the OHLC data.

Sample Response

The response from the API will be in JSON format, providing you with the necessary OHLC data:

{
"success": true,
"timestamp": 1756515964,
"base": "USD",
"date": "2025-08-30",
"rates": {
"NASDAQ": {
"open": 0.00038,
"high": 0.0004,
"low": 0.00037,
"close": 0.00039
}
},
