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 | Minimum trade volume required to place an ActivityBar cell |
The Volume Distribution ActivityBar study shows the prices of the ActivityData only when the volume of that ActivityData equals or exceeds a volume threshold.
Cells are added when the volume of an ActivityData interval meets the volume specified in the BlockSize input. Only ActivityBars that meet the minimum volume specified by the BlockSize input will add ActivityBar cells to the chart. The cells represent the range of each ActivityData bar that meets the volume qualifier.
This study draws letters in each cell, beginning with the letter "A" and ending with "Z." The letter in the cell is changed to the next letter with each interval of the ActivityData. When all 26 letters in the alphabet are used, the numbers 1-9 are displayed. When these are used, an asterisk (*) is displayed in the rest of the cells. The cells added by this study use a cycle of colors or the color specified by the DefaultColor input as per the inputs listed above.
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.
