What's Range interval and how do I select it?

Range bars allow users to analyze the price movement of financial instruments, while also reducing market noise. Range bars don’t take time into consideration and are therefore able to create the so-called 'clean chart effect.' A new bar is formed when prices reach a certain value set by the user.

How are Range bars built?

• A Range bar has an opening price (Open). The price movement is recorded when the bar is being formed. During that time, the size of the bar grows from the Open point either up or down, depending on the price.
• The difference between the highest (High) and the lowest (Low) bar value is considered as price movement.
• Whenever the High — Low point reaches Range interval, the formation of the bar finishes.
• If the price moves in the [Low, High] range, the closing point (Close) of the bar changes.
• When the price crosses the [Low, High] range, the bar closes and the new bar starts to form.

How do I select Range bars on the chart?

There are two ways.

• Select Range bars in the chart type menu in the top panel.

• Select Range interval in the interval menu in the top panel.

What does Range interval mean?

Range interval sets the range in which the price moves, which in turn initiates the formation of a new bar.

1 Range equals one minimum price change. This value can be presented with the following formula.

1 Range = Tick Size

The values Tick Size are displayed in the Symbol Info menu (Right click on the chart series -> Symbol Info...).  

Please note that the time parameter does not affect Range bars, therefore when you choose the Range chart type, the interval of the chart will be automatically switch to Range interval by default or to the last used Range interval.
