Custom Pine Volume Indicator

I rely on a closed-source TradingView volume study for fast intraday decisions and want its behaviour recreated—then taken a step further—in modern Pine Script (v5). Your task is to match the original indicator bar-for-bar while adding the flexibility the locked script denies me.

What the finished indicator must do
• Plot the same volume-based signals the proprietary study produces so I can switch seamlessly.
• Draw clear visual annotations that flag exceptional buy/sell pressure and colour-code the histogram or overlay for instant recognition.
• Fire fully configurable custom alerts (app, email, webhook) that include dynamic variable values.
• Highlight suspected market-maker activity—think volume spikes relative to recent bars or other logic you propose—so I don’t need to hunt manually.

Essential details
• Optimised for intraday charts; real-time recalculation is critical.
• Parameters (thresholds, colours, alert text) exposed in the settings panel, no code edits required.
• Clean, well-commented Pine v5 code delivered with a short README and a quick screen-capture or Loom clip proving like-for-like performance.

I will confirm parity and new features on several one-minute and five-minute symbols before releasing payment. Quick, clear communication and a tight turnaround will help seal the deal.
