Session Open Candle Marker

The "Session Open Candle Marker" is a Pine Script indicator designed for forex and futures traders using Smart Money Concepts (SMC) and RP Profits-inspired strategies. It marks the 15-minute opening range candles for the Asia, London, and NY sessions, where institutional "big players" often gather liquidity. Each session’s range is drawn as a rectangle with a customizable midpoint line, ideal for spotting breakouts, retests, and liquidity sweeps.
Features


Session Open Ranges: Plots rectangles for the 15m open candles of Asia (03:00 EEST), London (10:00 EEST), and NY (15:00 EEST), corresponding to 01:00, 08:00, and 13:00 GMT+1.

Customizable Visualization:

Toggle each session (Asia, London, NY) on/off.

Independent high/low label toggles for each session.

Adjustable rectangle color, midpoint line color, style (solid/dashed/dotted), and width.

Customizable rectangle duration (default: 96 bars, ~24 hours on 15m).



Timezone Flexibility: Default times are set for EEST (UTC+3). Adjust session inputs for your chart’s timezone (e.g., GMT+1: Asia 01:00, London 08:00, NY 13:00; UTC: Asia 00:00, London 07:00, NY 12:00).



Clean Design: Rectangles and labels update dynamically, with proper cleanup to avoid clutter.

Usage:

Setup: Add to a 15m chart (e.g., EURUSD, ES1!). Check your chart’s timezone (Chart Settings > Symbol > Timezone) and adjust session times if needed.

Settings:

Toggle sessions and labels to focus on desired ranges (e.g., London and NY for high volatility).

Customize colors, midpoint line style/width, and rectangle duration.

Trading:

Breakouts/Retests: Trade breakouts above/below the rectangle high/low, with retests back to the range or midpoint (aligned with RP Profits scalping).

Liquidity Sweeps: Watch for price sweeping session highs/lows, reversing for entries (SMC concept).
