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 are fields in the income statement 1,000 or 1,000,000 times larger than reported in their SEC filings?
Firstly, check if the financial statements are denominated in thousands or millions in their SEC statement. If this is not the case it is likely that our pull from the SEC is not denominated properly, which can affect just the shares outstanding (and diluted), or the entire statement. If you run into a rare instance of this please reach out to us here and we can get it fixed for you in a timely manner.
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.
