These charts are a graphical representation of the asset that indicate the price movements over a given timeframe. Candlestick dates back to the 17th century Japan but in the early 20th century, it has been redefined. It comprises candlesticks and each candlestick represents the same period of time. For example, a 1-minute chart shows candlesticks representing a period of one minute while a 1-day chart shows candlesticks representing a period of one day and so on.
They are made up of four data points: High, Low, Open and Close (also known as OHLC values). The High and Low represent the highest and the lowest recorded price respectively while Open and Close represent the first and the last price respectively over a particular time frame. These charts are widely used in analysing financial data and for performing technical analysis of Bitcoin.
