An Open High Low Close (OHLC) chart is a common type of financial chart used to display price movements of a security or asset over a specific time period, such as a day, week, month, or even intraday intervals. The OHLC chart provides a comprehensive visual representation of four key data points for each period: the opening price, the highest price, the lowest price, and the closing price.

The opening price is represented by a short horizontal line extending to the left, the closing price by a short horizontal line extending to the right, the highest price by the top end of a vertical line, and the lowest price by the bottom end of the vertical line. The length of the vertical line indicates the price range (high to low) for that specific period, while the position of the horizontal lines in relation to the vertical line reveals whether the closing price was higher (bullish) or lower (bearish) than the opening price.

OHLC charts are widely used in technical analysis to identify price patterns, trends, and potential reversal points. Traders and analysts often use these charts to make informed decisions about buying or selling securities based on price action and historical patterns. OHLC charts can be combined with various technical indicators to gain further insights into market behavior and improve trading strategies. The OHLC format is the foundation for other types of financial charts, such as candlestick charts, which offer similar information in a more visually appealing way.

An Open-High-Low-Close (OHLC) chart is a type of financial chart used to represent price movements of assets like stocks, currencies, or commodities over a specific period. Each vertical bar on the chart displays four key data points: the opening price (O), the highest price (H), the lowest price (L), and the closing price (C) for that period. The top of the bar indicates the high, the bottom shows the low, and small horizontal ticks mark the open (left) and close (right).

OHLC charts help traders analyze market trends, volatility, and price patterns. They are widely used in technical analysis to identify support/resistance levels, breakouts, and potential reversals, making them a fundamental tool for decision-making in trading.
