Data Coverage

Q: Where does the real-time data come from? Is it sourced directly from the exchanges?

For stocks, spreadsheet users receive real-time quotes directly from the IEX exchange, covering all actively traded U.S. stocks including those listed on Nasdaq and NYSE. API users receive Smart Mid, a proprietary price model derived from IEX data that estimates fair value based on top-of-book depth, recent trades, and quote activity. While not consolidated across all exchanges, it provides a fast, liquidity-aware view of the market for non-commercial use. For options, real-time data is delivered directly from OPRA, aggregating feeds from all U.S. options exchanges including Cboe, NYSE, and Nasdaq. This ensures pricing is fully aligned with official exchange prices.

Q: Do you offer delayed data for cost savings?

Yes, we offer a low-cost Starter Plan that includes 15-minute delayed data—ideal for users who don’t need real-time access and want to keep costs down. It includes access to a wide range of asset classes, including stocks, options, and mutual funds, making it a great entry point for personal projects or casual research.

Do you offer pre-market and after-hours data?

Yes, we include both pre-market and after-hours trading data for all the stocks we support. You can access it through the API or directly in Google Sheets using our add-on.

How far back does your historical data go?

We offer historical stock and options data and going back to 2010. For some stocks, data may be available further back, depending on the symbol.

Can I use your data for commercial or display purposes?

No—our self-service plans are for personal, internal use only. Commercial use, redistribution, or any kind of public display requires a separate agreement. Please contact our sales team if you’re interested in licensing data for commercial purposes.

What’s the difference between your free and paid data access?

All plans use the same high-quality data sources, but access levels vary.

Free plans are limited to historical data only. You can’t access today’s data, and yesterday’s data becomes available after the market opens the following trading day at 9:30 a.m. Eastern Time. Historical access is also limited to a maximum of one year.

Paid plans include access to real-time and/or 15-minute delayed data, depending on the plan you choose. You’ll also get access to the current day’s data and historical coverage beyond one year.

Example: If today is Tuesday, free users can access Monday’s data starting at 9:30 a.m. ET on Tuesday.

Do you offer delayed data for cost savings?

Yes, we offer a low-cost Starter Plan that includes 15-minute delayed data—ideal for users who don’t need real-time access and want to keep costs down.
