This simple indicator is to show the impact of given dates on the chart: The dates need to be entered in a yyyy-MM-dd format, separated by comma (,) or space+comma ( ,). The event can be shown on the chart with a vertical highlighting. The midpoint of the price action that day can be shown as a vertical line.
Hint: If you load a lot of dates into it, best disable the "Indicator Arguments" in "Chart Settings" -> "Status line" to not have the chart littered with these date arguments.
