Session ParmezanForex Session Range Boxes (Asia, Europe, US) — visual intraday session tracker for Forex and metals.
This indicator automatically marks the three major Forex trading sessions — Asian (Tokyo), European (London), and American (New York) — directly on your chart using dynamic colored boxes.
Each box represents the full price range (High–Low) formed during that session, helping traders visualize how volatility and liquidity evolve across the global trading day.
The script is built for intraday traders and session-based strategies, especially those who monitor breakouts from the Asian range or reactions during London–New York overlaps.
⚙️ Features
• Accurate session timing (UTC+3 / Moscow Time) — Asia: 03:00–12:00, Europe: 11:00–20:00, US: 16:00–01:00.
• Dynamic range boxes: each box expands in real time as new highs and lows are set during the session.
• Clear visual separation: each session is shown in its own color (blue for Asia, orange for Europe, green for US).
• Automatic daily reset — new boxes start every new session.
• Intraday focus only — visible up to the 1-hour timeframe (M1–H1) for clarity.
• Transparent design — semi-transparent fills keep candles readable even when sessions overlap.
• Lightweight performance — optimized use of box.new() and var variables avoids lag on lower timeframes.
🧭 Typical Use-Cases
• Identify Asian session ranges and watch for London breakouts or New York reversals.
• Visually align your intraday strategy with session volatility cycles.
• Combine with VWAP, liquidity zones, or market profile indicators for deeper confluence.
• Spot overlapping sessions — often the most active periods of the day.
