#chart {

}
Open and close prices are displayed as left and right tick marks. To specify these prices, use the openValueField and closeValueField properties.
To reflect changes on the market, the Chart component compares the price of every point with the price of the previous point. The Chart paints the points whose price has decreased in a specific reduction color. To switch between high, low, open or close prices of points as sources for data comparison, use the series.reduction.level property.
Additionally, use the tooltip.contentTemplate property to declare a custom tooltip that shows prices. You can also enable the argumentAxis.workdaysOnly property to display only the work days on the argument axis.
