what is the use of candlestick patterns in trading ?

What is a candlestick? A candlestick is a way of displaying information about an asset's price movement. Candlestick charts are one of the most popular components of technical analysis, enabling traders to interpret price information quickly and from just a few price bars.

Traders use candlestick charts to determine possible price movement based on past patterns. Candlesticks are useful when trading as they show four price points - open, close, high, and low - throughout the period the trader specifies. Many algorithms are based on the price information shown in candlestick charts.
