Previous Day and Week Ranges

I've designed the "Previous Day and Week Ranges" indicator to enhance your trading strategy by clearly displaying daily and weekly price levels. This tool shows Open-Close and High-Low ranges for both daily and weekly timeframes directly on your trading chart.

Key Features:

• Potential Support and Resistance: The indicator highlights previous day and week ranges that may serve as key support or resistance levels in subsequent trading sessions.
  
• Customizable Display Options: Offers the flexibility to show or hide daily and weekly ranges based on your trading needs.
  
• Color Customization: Adjust the color settings to differentiate between upward and downward movements, enhancing visual clarity and chart readability.
  

This indicator is ideal for traders aiming to understand market dynamics better, offering insights into potential pivot points and zones of price stability or volatility.

Added another Addon:
- session volume profile PoCs (historical Pocs)
- naked / untapped Pocs

版本注释:

Had to revert the nPoc rendering. It will be included in the next update after resolving the issue.

版本注释:

New Addon: Added Session Volume Profile (SVP) and rendering of the Nearest Naked (untapped) Point of Control.

版本注释:

Displays Session Volume Profiles (SVP) with the nearest naked Points of Control (PoC) above and below the current price.

版本注释:

Enhancements:

• markVisitedPocs(): Improved logic to mark Point of Control (PoC) lines as visited. The function now iterates through PoC levels more efficiently, updating the line color and marking the PoC as not naked when it falls within the current bar’s high and low range.
  
• selectNakedPOCs(): Enhanced functionality to select the last two naked PoC levels, one above and one below the current close. The function now handles edge cases and ensures accurate selection of PoC levels, improving overall reliability and performance.
  

版本注释:

Fixed an issue where the Previous Day POC was naked and resulted in two lines being plotted. Now, only a single line is displayed without overlaps.

版本注释:

Resolved overlapping of daily, weekly, and monthly lines.
