Candlestick charts show the evolution of a stock market symbol price over a period of time. Each "point" illustrates the opening price at the start of the day (or month, or year), the closing price at the end of the day (month, year), the highest and lowest variation during this time. The body is like a candle, between the open and close values. It may use alternative colors - or black and white, as a filled or empty candle - to show a positive or negative variation. Outer sticks show the highest and lowest trade value for each point.
Our Stock Variation single-series demo charts illustrate open and close, high and low values at the end of each year. All our candlestick and OHLC charts, and their variations, use the same main data: open, close, high and low stock values for some random XPSW stock symbol, every year between 1999 and 2016.
