Aftermarket Quote API FAQs

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.

Does real-time stock quote cover pre-market and after hours?

Yes, we have real-time stock quote for pre-market and post-market data. The data can be found here https://financialmodelingprep.com/api/v4/pre-post-market-trade/AAPL?apikey=your_api_key and https://financialmodelingprep.com/api/v4/pre-post-market/AAPL?apikey=your_api_key

Why are after-market and pre-market prices different from other platforms?

After-market and pre-market prices can vary between platforms due to differences in data sources and low trading liquidity during those sessions. We use multiple exchange feeds to provide this data, but some brokers and platforms rely on proprietary or restricted feeds that we can't redistribute due to compliance limitations. As a result, you may notice slight differences in prices—especially for lower-volume stocks or during off-hours trading. If you’re seeing significant discrepancies, feel free to share the sources you're comparing us with, and we’ll be happy to investigate further. Just keep in mind that pre/post-market pricing often varies depending on the exchange and broker used.

What price is displayed after the market closes until it opens again for equities?

For equities, there is no price displayed after the market closes until it opens again. However, you can check this data during pre and post-market hours using the Aftermarket Trade API.

Why does the /stable/aftermarket-quote?symbol=AAPL API return zero volume for the current time?

The volume displayed in the API represents the day volume. If the market is not open yet (pre-market), the volume will be zero. For the volume of the last trade, it is displayed as lastSaleSize.

What is the upper limit of the number of symbols I can give to the batch aftermarket API?

The upper limit for the number of symbols you can give to the batch aftermarket API is 1,000 symbols.

What timezone does the quote API for stocks and forex use?

The timezone for the quote API is aligned with the timezone of the exchange that the symbol trades on.
