What this script says

Opening Range Dashboard is an indicator drawn over the price chart.

You can change 2 inputs: `range_start` (default 09:30) and `range_end` (default 10:00).

It remembers `or_high` and `or_low` from one bar to the next.

It calculates `in_range` as whether the time of day is between `range_start` and `range_end`.

On each bar, it checks whether the time of day is `range_start` and, if so, sets `or_high` to the high and sets `or_low` to the low; otherwise, if `in_range`, sets `or_high` to the max (a `or_high`, b the high); it also sets `or_low` to the min (a `or_low`, b the low).

On the chart, it shades the background when `in_range`, draws a horizontal line at `or_high`, draws a horizontal line at `or_low` and shows a dashboard.
