Analysis Techniques & Strategies
| Name | Expression | Default | Description |
| ApproxNumRows | Numeric | 10 | Approximate number of rows of cells to generate per bar. |
| CycleColors | True/False | True | Determines if cell colors should change on a rotating basis (minute-based Activity Data only). |
| DefaultColor | Numeric | DarkGreen | Color used for cells when CycleColors is set to False. |
| BlockSize | Numeric | 1000 | Volume divisor used to determine the number of cells to add. |
| MaxWeight | Numeric | 5 | Maximum number of cells to add for any one price range. |
The Volume Strength ActivityBar study displays a column of cells representing the price range of each ActivityData bar; additional columns of cells are added for each ActivityData bar representing multiples of the volume specified in the input BlockSize.
In this way, each ActivityData bar is given more weight (width or columns) based on its volume.
When the CycleColors input is set to True, the cells change color after a certain number of minutes, which is specified by the Interval setting on the Data Settings tab of the Format ActivityBar dialog box. When it is set to False, the color specified in the DefaultColor input is used for all cells.
The ApproxNumRows input determines the approximate number of cell rows placed between the high and low of the ActivityBar. The setting is approximate because the number of rows is dependent, in part, on the price range of that bar with respect to the range of other bars on the chart. This input controls the resolution of cells; if greater resolution is needed, , increase the ApproxNumRows input. Increasing the resolution also increases the system time required to update a chart.
By default, no alert criteria are included in this ActivityBar study.
