A candlestick chart is a type of financial chart that graphically represents the price moves of an asset for a given timeframe. As the name suggests, it’s made up of candlesticks, each representing the same amount of time. The candlesticks can represent virtually any period, from seconds to years.
Collectively, this data set is often referred to as the OHLC values. The relationship between the open, high, low, and close determines how the candlestick looks.
The distance between the open and close is referred to as the body, while the distance between the body and the high/low is referred to as the wick or shadow. The distance between the high and low of the candle is called the range of the candlestick.
