This listing offers a single free dataset: one month (2020) of US Equity Standard Adjusted Daily OHLC data, delivered as CSV. It carries no cost and no commitment. You get market-hours-only daily open, high, low, close, and volume figures, adjusted for corporate actions like splits and dividends, and derived from SIP trades. Because pricing has one dimension at no charge, there are no tiers, usage add-ons, or scaling options to compare. This is a fixed, self-contained data sample rather than a recurring subscription or metered product.
Top-of-mind questions for buyers
What exactly is one record in this daily OHLC dataset?
Each row represents one US equity for one trading day in 2020. It carries market-hours-only open, high, low, close, and volume figures. Prices are adjusted for corporate actions like splits and dividends, and derived from SIP trades. The file covers one calendar month and arrives as CSV.
Does the free CSV carry any exchange fees or later charges?
No. This is historical daily data, and historical US equity data carries no exchange fees. The listing is free with no cost and no commitment. Exchange fees apply only to real-time or delayed streaming feeds, which this sample is not.
How does the "adjusted" version differ from the standard daily OHLC?
The adjusted dataset recalculates open, high, low, close, and volume for corporate events such as splits and dividends. The non-adjusted standard version reports the same market-hours-only figures without those corrections. Adjustment gives a continuous view of returns across events. Both derive from SIP trades.
