1BullBear™ - Sessions

1BB Sessions — Multi-session high/low tracker for the four major global trading windows, with automatic DST handling.

What it shows

For each of Tokyo, London, Premarket (US), and New York, the indicator draws:

• A top line tracking the running session high
• A bottom line tracking the running session low
• A single-character open marker above the first bar (T / L / P / N)

Each session is evaluated in its own local time, and DST is handled automatically — US sessions follow EDT/EST (2nd Sunday March → 1st Sunday November), London follows BST/GMT (last Sunday March → last Sunday October), Tokyo is fixed JST year-round.

Default windows (city local time)

• Tokyo 09:00 – 15:00
• London 08:00 – 11:00
• Premarket 07:00 – 09:00
• New York 09:30 – 16:00

Inputs

• Show / hide each session independently
• Pick a custom color per session

Notes (V1)

First port of the Sessions module from the Pine Script v6 indicator "1BullBear" by KweeBoss_ (TradingView, MPL 2.0).

LipiScript doesn't currently expose drawing primitives (no box.new, line.new, or label.new), so the original Pine boxes are approximated using paired plots for the top/bottom and per-bar character markers for the opens. If LipiScript adds those primitives — or relaxes some of the parser constraints around float math and typing inside functions — a V2 with editable times, background fills, and proper labels becomes straightforward.
