Daily Levels [cryptalent]

2小时前

Daily High / Low / Mid / Open Levels is a session-based reference indicator designed to visualize key daily price levels directly on the chart.

This indicator automatically plots the Daily High, Daily Low, Daily Midpoint (High + Low / 2), and Daily Open as horizontal lines for each trading day. These levels help traders quickly identify important structural prices where liquidity, reactions, or acceptance often occur.

Key Features
Automatic Daily Levels

• Plots Daily High (H), Low (L), Mid (M), and Open (O) using higher-timeframe daily data.
  

• Levels update in real time as the current day develops.
  

Multi-Day History

• Displays daily levels for a configurable number of past days.
  

• Older levels are automatically removed to keep the chart clean.
  

Line Extension

• Current day levels can be extended forward by a user-defined number of bars.
  

• Useful for projecting intraday reaction zones and liquidity targets.
  

Visual Customization

• Independent line width and color settings for each level.
  

• Mid level is shown as a dashed line for quick visual distinction.
  

Labels & Price Tags

• Optional letter labels (H / L / M / O) displayed near the extended levels.
  

• Optional price labels showing the exact level values on the right side of the chart.
  

• Labels update dynamically and only display for the active trading day.
  

Performance-Oriented Design

• Efficient line and label management using arrays.
  

• Automatically cleans up unused objects to stay within TradingView limits.
  

Use Cases

• Identifying intraday support and resistance
  

• Tracking daily range behavior
  

• Monitoring mean reversion vs. range expansion
  

• Aligning intraday execution with higher-timeframe structure
  

This indicator is particularly useful for traders who rely on market structure, session behavior, and objective price references rather than subjective trend lines.
