Standard Deviation API FAQs
How can I retrieve historical intraday price data for more than 1 month?
To retrieve historical intraday price data for more than 1 month, you will need to implement a loop that iterates over day intervals covering the entire desired time range. This approach ensures a suitable response speed for the data being returned. For example, if you require more than 1 month of 30-minute data, you can make queries over day intervals to cover the entire desired time range. Here is an example link for retrieving 1-minute data: https://financialmodelingprep.com/api/v3/historical-chart/1min/AAPL?from=2024-12-04&to=2024-12-06&apikey=YOUR-API-KEY
Why am I not receiving all the data for historical intraday price data on the API?
Due to the size and volume of historical intraday price data, there are limits to the number of records that can be returned in a single query. You may need to make queries over multiple periods to retrieve all the data you need. If you require more data than what is being returned, you can implement a loop to iterate over intervals covering the entire desired time range.
How can I request one particular minute's bar data?
You can use the Intraday chart API endpoint with the specific date and stock symbol to request one particular minute's bar data. For example, you can use the following URL format: https://financialmodelingprep.com/api/v3/historical-chart/1min/AAPL?from=2025-02-28&to=2025-02-28&apikey=YOUR-API-KEY
Does the intraday historical market cover pre-market and after hours?
Yes, the historical market data for pre-market and post-market data can be found here https://financialmodelingprep.com/api/v4/historical-price/AAPL/1/minute/2021-06-11/2021-06-11?apikey=your_api_key or https://financialmodelingprep.com/api/v3/historical-chart/1min/AAPL?from=2021-06-11&to=2021-06-11&extended=true&apikey=your_api_key
How many years of intraday data I can get in one query?
Due to the sheer size and volume of the historical intraday price data there are limits to the number of records that can be returned in a given query. Contact our support team for more information.
Do you provide after-hours financial data through your API?
Yes, you can use the Aftermarket Quote API for after-hours financial data. You can find more information about it in the documentation.
Is the Intraday price adjusted?
Yes, the intraday data is adjusted for split.
