Time Sessions – Asia/London/New York

Hi all, forgive me for using LLMs to create this but as mentioned in my first post I am not a programmer nor do I have any real programming skills to speak of.

I did however want to share this session box indicator I vibe coded that imitates the one on the Bloomberg Terminal (by memory, its been a very long time since I used it).

I did look around the forum and the other ones didn’t quite match this one. If it is too iterative to an existing indicator someone else has posted I am more than happy to take this down.

The default time zones are configured assuming you are using New York as the baseline – feel free to edit the code to match your desired or local time zone.
