Overview
The Trailing Peak Activity Level identifies the price levels at which the most trading activity occurred within a given session window. Using a combination of volume-weighted analysis and ATR-based band detection, it highlights the "high-activity nodes" price levels where large orders were placed and where price is most likely to react in future sessions.
Unlike static VWAP or fixed pivot levels, these zones trail dynamically as new session data arrives, giving you an always-current picture of where the market considers "value."
How It Works
- Session boundary detection: The indicator resets at the start of each configurable session window (default: London + New York).
- Volume profile construction: As each bar closes, volume is accumulated against its price range to build a rolling intra-session volume profile.
- Peak identification: The price level with the highest cumulative volume (Point of Control / POC equivalent) is identified and plotted as the "Peak Activity Level" line.
- ATR trailing zone: An ATR-based band is drawn around the PAL, widening in high-volatility conditions to define the full activity zone.
How to Use
- Use the Peak Activity Level (PAL) line as a dynamic support/resistance zone during the session.
- Price bouncing off the PAL with reduced volume = continuation trade opportunity.
- Price breaking through PAL with high volume = potential momentum trade.
- End-of-session PAL often becomes next session's key reference level.
- Best used alongside session-based indicators (e.g., VWAP, Session Highs/Lows).
