Market Value

FreeValueStandardPro

Get the latest market value snapshot for one or more stocks.

• Returns a real-time market value derived from the last BBO quote from the Nasdaq Basic feed if the account has a stocks standard or pro subscription.
• Returns a 15-minute delayed market value derived from an NBBO quote from the UTP & CTA feeds if the account has the stocks value subscription subscription.

• Theta Data resets its snapshot cache at midnight ET every day. This endpoint may not work on a weekend where there were no eligible messages sent over exchange feeds. We recommend using historic requests during the weekend.
