Intraday Liquidity Sweep Indicator Upgrade

I already have a Pine Script dashboard that flags higher-time-frame liquidity sweeps, but I now need that logic refined for intraday work. The new version should track and display whether price has run the current session low or high in real time, broken down by the three key sessions I trade:

• New York Session
• London Session
• Asian Session

You can either modify my existing code or start from scratch as long as the finished indicator keeps the same clean dashboard style and remains fully compatible with TradingView’s latest Pine Script version.

Core requirements
• Detect and mark each session’s low and high as they form, then highlight any subsequent sweep of those levels.
• Show an at-a-glance dashboard panel that turns green when a high is swept and red when a low is swept, with optional alerts.
• Session times must be editable so I can fine-tune the exact open and close windows.
• Code needs to be commented clearly so I can maintain it later.

Acceptance test
I will add the script to a chart, apply it to at least three symbols, and confirm that the dashboard updates correctly through one full trading day, accurately identifying every sweep of the defined session highs and lows.

If any part of the brief is unclear, feel free to ask before coding so we can keep revisions to a minimum.
