<div style="background-color: #E3FBE5;">Note: If 1-Tick resolution is used, only the following chart types are available: Dot on Close, Line on Close, Invisible Bar</div>

<br>

Each bar in a time-based chart is based on a tick group that consists of all ticks over a defined interval of time. The first tick of the group forms the bar's Open component, the tick with the highest price forms the bar’s High component, the tick with the lowest price forms the Low component, and the last tick of the group forms the bar's Close component. The first tick with a time stamp past the original bar’s interval forms the next bar’s Open component.

<br>

The bar's Open component is always one tick above or below the Close component of the previous bar, and the bar’s Close component is always at the High or the Low of the bar. All the bars are of the same height, equal to the range. The next bar is started once the tick with a price outside of the original bar's range has been received. If the price movement is greater than the combined range of two consecutive bars, additional "virtual" bars are inserted between the bars to fill the gap.

A range-based chart can only be created from tick data.

Each bar in a volume-based chart is based on a tick group that consists of successive ticks for a defined number of contracts. The first tick of the group forms the bar's Open component, the tick with the highest price forms the bar's High component, the tick with the lowest price forms the Low component, and the last tick of the group forms the bar's Close component. The bar is closed once a tick, bringing the current bar’s total to the defined number of contracts, has been received. If the last tick’s volume is grater than is required to complete the current bar, the tick is split. The volume required for the current bar is used for that bar, and the balance is used to start the next bar.
