Asia & London Session High/Lows by Erdi

his script identifies and plots the highest high and lowest low of the Asian and London trading sessions based on the UTC+2 timezone. Unlike typical session indicators, the horizontal lines start exactly at the bar where these extreme points occurred and extend forward, allowing traders to visually track key session levels throughout the day.

Sessions defined:

Asian Session: 02:00 – 09:00 (UTC+2)

London Session: 09:00 – 15:30 (UTC+2)

Features:

Detects and fixes the highest high and lowest low within each session.

Draws horizontal lines from the exact bar where the extreme occurred, extending into the future.

Uses gray color for Asian session levels and green for London session levels.

Automatically resets at the start of a new trading day.

This indicator helps traders easily visualize important session levels for potential support and resistance, improving intraday decision-making.
