A complete session-based trading toolkit combining Asia/London/NY session levels, first-FVG-per-session tracking with history & mitigation, and multi-timeframe previous high/low levels — all in one indicator.
🌏 Session Highs & Lows
- Tracks Asia, London, and NY session highs/lows in real time
- Fully customizable session times (built around New York time by default)
- Independent master toggle per session — turn any session's lines on/off entirely
- Smart decluttering: your current session's own prior-day line automatically hides while you're inside that session (no redundant overlap with the live line), while the other two sessions' most recent levels stay visible
- Optional live-updating lines that track to current price, with labels that can stay fixed to avoid clutter near price action
💎 Session-Based Fair Value Gaps
- Captures the first FVG of each session — Asia, London, NY — independently
- Dotted midpoint (equilibrium) line through every FVG
- Configurable history: keep the last N FVGs per session instead of just the current one
- Full mitigation tracking — active and historical FVGs fade automatically once price closes through them
- Toggle live-extension on/off, or cap FVGs to end at session close
📅 Previous Day / Week / Month Levels
- Non-repainting previous D/W/M high & low
- Optional 50% Equilibrium line for each timeframe
- Fully custom colors per timeframe
⏱️ Intraday & Custom Timeframe Levels
- Previous 4H and 1H high/low, independently toggleable
- Pick any timeframe you want with a native TF selector — get previous high/low for whatever period matters to you
✍️ Custom Manual Levels
- Draw your own high/low levels at any price you choose — great for marking news levels, targets, or manual S/R (Support and Resistance)
⚙️ Built for Reliability
- All levels use direct bar-by-bar tracking rather than higher-timeframe lookups — consistent, accurate results across every chart resolution
- Every module has its own toggle, so you can run this as a full session/FVG/level suite or strip it down to just what you use
