1. BAR CHART
The chart is created with the use of bars where each bar has a high (top) and a low (bottom) with a line on either side; right side being the opening price and the left side being the closing price for the selected time period (4 hours intervals selected in the example chart above).
Different colours can be used to identify bars that close higher than the open (bull or up bars) or lower than the open (bear or down bars). The example above has green lines for up bars and red bars for down bars. The following section will show you how to make such customisations as colour and gridlines.
