OHLC chart (stock)

An OHLC (Open, High, Low, Close) chart shows the price changes over time for stocks, bonds, currencies, commodities, and other types of financial instruments. Each bar corresponds to a time unit, for example, one day, hour, or minute. This chart type is frequently used in the technical analysis of financial market trends.

The following table shows the main elements of a typical OHLC bar.

Image	Item	Explanation
	Low	The lowest price traded in the time unit represented.
	Open	The price at the beginning of the time unit represented.
	Close	The price at the end of the time unit represented.
	High	The highest price traded in the time unit represented.

When to use

OHLC charts can help you detect, predict, and monitor the trends of the stock prices, assisting you in the stock buying or selling decisions. For example, you can compare the low and high prices (or the opening and closing prices) for adjacent OHLC bars. A series of three successive bars with higher high prices and higher low prices may indicate an ascending trend of the price.
