Open-High-Low-Close (OHLC) charts display price action using vertical bars with horizontal tick marks. A left tick marks the open price, a right tick marks the close price, and the vertical bar spans the high-to-low range. They convey the same information as candlestick charts but with a more compact, traditional aesthetic preferred by many professional traders.
