Previous Day OHLC + Open Marker
This indicator is designed to help traders quickly identify the most important price levels from the previous trading session and today’s open. It provides a clean and configurable overlay of the previous day’s OHLC (Open, High, Low, Close) along with the current day's opening price, making it easy to spot price reactions, liquidity sweeps, and confluence zones.

Each line is independently toggleable
Fully customizable in color, transparency, and thickness
✅ Today's Session Open (DO)
Marks the current day's opening price
Helps identify directional bias, trend/momentum shifts, or mean-reversion points
✅ Minimalist Labels for Clarity
Text-only labels like H, L, O, C, and DO — no bulky label boxes
Color-matched to each line for visual simplicity
Optional display to keep charts clean
✅ Session-Based Highlight Zone
Optionally highlights the area between the previous day’s High and Low with a shaded box
Useful for identifying the day’s value area or range breakouts
✅ Smart Alerts

Helps you catch key interactions without watching the chart constantly
🧠 Ideal For
Intraday traders using VWAP, order blocks, or liquidity concepts
