Multi-Period Previous Value Area & POC [High Precision]
Overview
This indicator is a powerful tool for traders who utilize Volume Profile and Market Profile concepts in their daily routine. It automatically calculates and projects the Value Area High (VAH), Value Area Low (VAL), and Point of Control (POC) from previous periods (Daily, Weekly, and Monthly) onto your current chart.
Unlike basic pivot indicators, this script uses Lower Timeframe (LTF) data to reconstruct the volume distribution of the past periods, ensuring a professional level of accuracy.
Key Features
Multi-Timeframe Integration: Overlay Daily, Weekly, and Monthly Value Areas simultaneously to identify "confluence zones" where different timeframes align.
High-Precision Calculation: Uses request.security_lower_tf to analyze price distribution at a granular level (e.g., using 1-minute data for Daily VA calculation).
Optimized for Different Assets: Includes a Tick Multiplier setting to adapt the calculation to different instruments.
Example: Set to 4 for NQ (Nasdaq Futures) or 1 for QQQ/SPY.
Historical Memory Management: You can decide exactly how many past periods to keep on the chart (e.g., last 5 days, last 4 weeks) to maintain a clean and lag-free workspace.
Full Visual Customization: Change colors, transparency, and line styles (Solid, Dashed, Dotted) to match your personal chart theme.
Technical Breakdown
Value Area (VA): Highlights the price range where a specific percentage (default 70%) of the volume took place. This represents "fair value" for the previous period.
Point of Control (POC): The price level with the highest volume concentration. It often acts as a significant magnet or support/resistance level in the current session.
Dynamic Projection: The boxes and lines automatically extend to the current bar, allowing you to see exactly how current price action reacts to historical value levels.
How to Use
Mean Reversion: Look for price returning to the previous POC or VAL/VAH levels after a breakout.
Trend Confirmation: If the price opens and stays above the previous Day's VAH, it indicates a bullish sentiment.
Confluence: When a Weekly POC aligns with a Daily VAH, that level becomes a high-probability area for a reaction.
Settings Tip: For the best results, ensure the "Calculation TF" is lower than the chart timeframe (e.g., if you are on a 15m chart, use 1m or 5m for the Daily calculation).

Phát hành các Ghi chú
UI Cleanup: Labels now visible on last period onlyIn this update, I optimized the visual management of labels to prevent chart cluttering.
Visibility Improvement: VAH, VAL, and POC labels are now displayed exclusively on the most recent period (Day, Week, or Month).
Historical Context: Boxes and levels from previous periods remain visible for historical analysis, but text labels are hidden to keep the chart clean and readable.
Performance: Minor improvements in object array handling.
