## Formula

Each window runs from the start to the end of its hours (asia_hours, london_open_hours, new_york_open_hours, london_close_hours) in its own time zone (asia_tz, london_open_tz, new_york_open_tz, london_close_tz). A bar is inside a window when it opens at or after the start and before the end; hours that end before they start run past midnight.

in_asia, in_london_open, in_new_york_open and in_london_close are true on the bars inside each window.
