OHLCV
OHLCV stands for Open, High, Low, Close, Volume—the five data points that summarize price action over a time period. It's the standard format for candlestick data.
Understanding the Concept
Every candle on your chart is OHLCV data. Open: first trade price in the period. High: highest price reached. Low: lowest price. Close: last trade price. Volume: total amount traded.
This compression is brilliant. Instead of storing millions of individual trades, you store 5 numbers per time period. A year of daily data is just 365 candles. You lose granularity but gain practicality.
OHLCV is available in different timeframes: 1-minute, 5-minute, hourly, daily, weekly. Shorter timeframes = more data, more noise, more storage. Longer timeframes = smoother trends, less detail.
Real-World Example
Bitcoin's hourly OHLCV at 2pm: Open $50,000, High $50,500, Low $49,800, Close $50,200, Volume 1,500 BTC. This single candle tells you the hour started at $50k, peaked at $50.5k, bottomed at $49.8k, ended at $50.2k, with 1,500 BTC traded.
