The time series is the visualization of a symbol with its current and historic data. For each point in time, the Open, Close, High and Low prices are plotted on the chart. You can change how the data is compressed (end of day, intraday or tick data see Changing the Data Compression) and how the data is plotted on the screen (for example, as a line chart, bar chart, point and figure chart or else see Changing the Chart Type).

Additionally, you can control how much historic data is displayed in the chart and what trading sessions are used in intraday charts, what styles and colors are used in the chart, and if you want to extend the time line to the future (that means, show an empty area at the right side of the chart to make room for trend lines or similar objects that extend into the future).
