OPEN-SOURCE SCRIPT
Updated IST Trading Sessions

Session ranges plotted in Indian Standard Time (UTC+5:30).
This is for traders trading forex in IST hours.
WHAT IT DRAWS
- A live box around each session's high and low, labelled inside the box
with the session name and its current range in dollars. No floating
labels cluttering the chart.
- Two dotted lines carrying the last completed session's high and low
forward, so you can see whether price is reacting to the Tokyo high or
the London low without scrolling back.
- Killzone shading over the first 90 minutes of the London and New York
opens.
- Previous day high and low.
- A summary table with each session's range in dollars and pips, and a
marker showing which session is currently live.
DEFAULT TIMES (IST)
Tokyo 05:30 – 14:30
London 12:30 – 21:30
New York 17:30 – 02:30
DAYLIGHT SAVING
India does not observe daylight saving, but London and New York do. The
defaults above are set for summer (BST / EDT), roughly mid-March to late
October. During winter, add one hour to the London and New York session
inputs. All three sessions are editable, so you can also set them to
whatever windows you actually trade.
KEEPING IT READABLE
Boxes are only drawn for the last N days, adjustable, which stops the
chart filling up on long scrollbacks. Carry-forward lines extend a set
number of bars and older ones are removed automatically. Background tint
is off by default; turn it on if you prefer shading over boxes.
NOTES
This is a visual reference tool. It generates no signals and makes no
suggestion about direction. Works on any intraday timeframe, though
session boxes are most useful on 5m to 1h.
