Candlestick

Candlestick charts are used by traders 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 of time the trader specifies.
Many algorithms are based on the same price information shown in candlestick charts.
Trading is often dictated by emotion, which can be read in candlestick charts.
