A candlestick chart is a type of price chart used in technical analysis that displays the high, low, open, and closing prices of a security for a given time period.
Candlestick price action requires forex traders to identify the location where the price opened for a period, where the price closed for a period, and the price highs and lows for a specific period. A price action analysis is useful because it can provide traders with insight into trends and reversals.
Traders use candlestick charts to forecast price movements based on past patterns. Candlesticks are useful in trading because they display four price points (open, close, high, and low) over the time period the trader specifies.
