An open-high-low-close chart (also known as OHLC chart) is a
type of chart typically used to illustrate movements in the price
of a financial instrument over time. Each vertical line on the
chart shows the price range (the highest and lowest prices) over
one unit of time, e.g. one day or one hour. Tick marks project from
each side of the line indicating the opening price (e.g. for a
daily OHLC chart this would be the starting price for that day) on
the left, and the closing price for that time period on the
right.
The Japanese Candlestick chart is another way of displaying
market price data, with the opening and closing prices defining a
rectangle within the range for each time unit. The rectangles have
different colours depending on whether prices rose or fell in that
period.
Both charts show the exact same data, i.e. the opening, high,
low, and closing prices during a particular time frame. Some
traders find the candlestick chart easier to read.
OHLC/Candlestick chart may contain single series or multi
series. These charts use four values, so you need to pass opening,
high, low and closing price values. Also you need to select
Label field.
