Session Highs and Lows Indicator

This indicator marks the high and low levels for key trading sessions, allowing traders to identify significant price zones across different markets. The default session times are defined in UTC and will automatically adjust to your local timezone:
- **London Session (07:00-09:00 UTC)**: Tracks intraday liquidity zones for potential highs/lows.
- **New York Session (12:00-14:00 UTC)**: Highlights volatility during market overlaps with Europe.
- **Asia Session (23:00-01:00 UTC)**: Confirms trend continuation and retracement opportunities.
- **New York Close Session (19:00-21:00 UTC)**: Focuses on reversals and breakout tests during global transitions.

The script dynamically updates session highs and lows with clear labels and dashed horizontal lines for better visualization. **Time ranges can be adjusted to suit your trading preferences.** This makes the indicator flexible and effective for liquidity hunting, trend trading, and breakout strategies.
