Monday Open [Bellsz]

Plots the NY Monday range with box, High/Low, EQ, and Monday Open, then projects those levels forward by N bars. Clean weekly framing for liquidity targets and mean reversion.

Purpose
Maps the full New York Monday (00:00–23:59 NY time) and projects its High, Low, EQ (midpoint), and Monday Open forward. Use it to frame the week’s liquidity map, “magnet” levels, and mean-reversion targets with one glance.

What it draws

• Monday Box — live-updating box for the NY Monday session (fill + border).
  
• High/Low (solid lines) — locked at Monday close and optionally extended N bars.
  
• EQ / Midline (dashed) — (High + Low) ÷ 2, extended N bars.
  
• Monday Open (solid line) — projected from Monday’s first bar, extended N bars during Monday (temporary), then replaced by a fixed Monday-Open line at session end.
  

How it works

• Detects NY calendar day without dayofyear and anchors to America/New_York.
  
• Starts tracking at NY Monday 00:00; updates the box/high/low in real time.
  
• When Monday ends, the script freezes the range and plots final H/L/EQ + Open, extending each by your chosen number of bars.
  
• No lookahead; levels are only finalized after Monday completes.
  

Inputs

• Extend lines (bars →) — how far to project H/L/EQ/Open into the future.
  
• Monday Box Fill / Border — style the range box.
  
• High/Low Line Color / Width — style Monday H & L.
  
• EQ Line Color / Width — style midpoint.
  
• Monday Open Color / Width — style the Monday open.
  

Why use this indicator

• Weekly bias framing: Monday’s range often acts as the reference box for the week’s expansion.
  
• Liquidity targeting: Equal highs/lows and EQ act as common magnet/rebalance areas.
  
• Confluence: Combine with sessions/killzones, FVGs, order blocks, or news timing.
  

Best practices

• Keep chart on your normal trading TF (M5–H1 for intraday, H4–D for swing).
  
• Watch EQ taps and previous Monday H/L sweeps Tuesday–Friday.
  
• Pair the projection length with your strategy’s average holding horizon.
  

Notes & limitations

• All timing is NY session-based (America/New_York). If your symbol trades Sunday evening (futures/FX), Monday begins at 00:00 NY as coded.
  
• Market holidays that shift liquidity can affect the “feel” of Monday’s range.
  
• Works on any symbol/TF supported by TradingView. No repainting after Monday close.
