What Session Opening Lines Does
Session Opening Lines is a TradingView indicator that marks the opening price of key market sessions directly on the chart.
It shows the Day Open, London Open, and US Open using Europe/Athens time. This helps traders quickly see where each important trading period started.

Why These Levels Matter
Session opens often act as important reference levels during intraday trading. Price may react around them, reclaim them, reject from them, or use them as support or resistance later in the session.
The indicator does not generate buy or sell signals. Its purpose is to keep clean session-based levels on the chart so the trader can read price action with better context.
Customization
The user can adjust the London and US session times, line colors, line thickness, line style, and labels. This makes it easy to adapt the indicator to different chart styles and trading workflows.
Overall, Session Opening Lines keeps the chart simple while highlighting the opening levels that matter most for intraday analysis.
