FX Sessions & Killzones EDT [Spring/Summer]

Just another sessions indicator. Among all the many existing ones, I didn't find anything simple that would cover my needs and that would actually be correct.
New York time is forced here for plotting the stripes so you don't need to worry about the time zone currently set on your chart. The indicator will be accurate during Daylight Saving Time (which, in 2023 for example, started on Sunday, 12 March , 02:00:00 and will be in effect until Sunday, 5 November, 02:00:00).

Versionshinweise:

UPDATE: Fixed the Asian Open Killzone.

Versionshinweise:

Asian range added.

Versionshinweise:

UPDATE: Added ICT Silver Bullet (range from 10:00 AM – 11:00 AM)

Versionshinweise:

UPDATE: Added the option to add / define one custom session (not displayed by default).

Versionshinweise:

When you like to be precise, as I do, you may find yourself frustrated with the level of inconsistency on this topic on the Internet.
I did my best to double check the relevant sources again, reconsile the time zones and get it right. Hence the necessaity of the update.

Release notes:
Start of Sydney session corrected.
Asian session added / split from Tokyo as they are technically not exactly the same thing.
Tokyo session corrected.
End of London (and Frankfurt) session(s) corrected.
End of New York session corrected.
London open killzone shifted backward.
London close killzone shifted forward.
New York open killzone extended backward.
Equities range (and equities closing / power hour) added for those who trade ES, NQ, etc.

Plus I have adjusted the default settings as I presume that most people would generally only want the Asian range and killzones.

Note: If you're wondering why ICT killzones generally start one hour earlier than the starts of the official FX sessions, then I guess that it's just extended to account for pre-market trading.

Here's an overview of the hours:

• Sydney Session = 5:00 PM – 2:00 AM EDT = 9:00 PM – 6:00 AM UTC
• Asian Session = 7:00 PM – 4:00 AM EDT = 11:00 PM – 08:00 AM UTC
• Tokyo Session = 8:00 PM – 5:00 AM EDT = 12:00 AM – 9:00 AM UTC
• Frankfurt Session = 2:00 AM – 11:00 PM EDT = 6:00 AM – 3:00 PM UTC
• London Session = 3:00 AM – 12:00 PM EDT = 7:00 AM – 4:00 PM UTC
• New York / North American Session = 8:00 AM – 5:00 PM EDT = 1:00 PM – 10:00 PM UTC
• ICT Asian Open Killzone = 7:00 PM – 9:00 AM EDT
• ICT Asian Range = 7:00 PM – 12:00 AM EDT
• ICT London Open Killzone = 2:00 AM – 5:00 AM EDT
• ICT London Close Killzone = 10:00 AM – 12:00 PM EDT
• ICT New York Open Killzone = 7:00 AM – 10:00 AM EDT
• Equities = 9:30 AM – 4:00 PM EDT
• Equities Closing / Power Hour = 3:00 PM – 4:00 PM EDT

Versionshinweise:

Complete overhaul for better user experience.
Start and end of all sessions now fully customizable.
Numbers removed from status line, cleaned up.
Sydney weekdays corrected.
Colors now a bit more distinct for better visibility on Mobiles.
Now includes all 3 time windows for the Silver Bullet setup.
An unobtrusive message will now appear on higher time frames (starting from the 2h) that "Some of the sessions may require lower time frames to appear."
I've done this primarily for myself but hopefully it can serve others as well.

Versionshinweise:

I noticed the script was not resetting to default values. Now fixed.

Versionshinweise:

A couple more adjustments to the colors so that it's better visible in light mode as well.

Versionshinweise:

I've added an option to set a custom session box showing the high and low of the given sesssion which can be useful for certain strategies.

And one more note: The time zone is hard set to New York which means that the start and end time of the sessions should actually be correct throughout the whole year, not just during summer / daylight saving time.
