What does OHLC stand for?
Open, High, Low, Close: the four prices that describe a market interval. Add volume and you have the basic building block of stock market analysis. What is OHLC data?
Is OHLC a trading platform?
No. OHLC is a stock market data API. It does not execute trades, manage portfolios or provide investment advice. Bring the data into your own product or workflow.
Is there a free stock market data API?
Yes. The Free plan includes 12,500 credits a day for AAPL, NVDA, JNJ, PEP, MSFT, SPY and QQQ, with end-of-day prices, delayed quotes, fundamentals and SEC filings, and needs no credit card. Developer adds every U.S. stock and ETF, and Pro adds listings in Canada, the UK, France, the Netherlands and Australia. Compare plans.
Is the data real-time?
No. Exchange quotes are delayed at least 15 minutes (international listings refresh hourly), crypto and currency pairs are snapshotted every few minutes, and end-of-day bars publish after the close. OHLC does not offer real-time or consolidated SIP data. The figures on this page are illustrative samples.
Which markets does OHLC cover?
U.S.-listed stocks and ETFs; on Pro and above, seven exchanges outside the U.S. (Toronto, TSX Venture, Cboe Canada, London, Euronext Paris and Amsterdam, and the ASX), U.S. options, crypto and currency pairs, and index levels; and on Commercial and Scale, U.S. and Canadian mutual funds and U.S. corporate bonds. Browse every dataset.
Can I use OHLC with Claude or ChatGPT?
Yes. The OHLC MCP server gives an assistant one tool per dataset plus the API documentation, on Developer and above. Connect Claude.
