_2523MTF Supertrend line

This script is designed to provide a comprehensive multi-timeframe overview of market trends by overlaying several different "SuperTrend" indicators onto a single chart. Instead of forcing you to switch back and forth between different timeframes (like moving from a 15-minute chart to a 4-hour chart), this tool brings that information to your current screen simultaneously.

Core Functionality

Multi-Timeframe Synchronization The primary logic of the script is its ability to pull data from four different timeframes at once. It calculates and displays trend lines for:

  • Short-term trends (e.g., 15-minute or 30-minute)
  • Medium-term trends (e.g., 1-hour)
  • Long-term trends (e.g., 4-hour or Daily)

By viewing these together, you can see if the "big picture" trend aligns with the "minor" price movements, helping to identify high-probability trading opportunities.

Smart Automation & Display The script includes an intelligent "AutoDisplay" feature. When enabled, it detects which timeframe chart you currently have open and automatically selects the most logical set of higher timeframes to display. For example, if you are viewing a 1-minute chart, it will choose smaller increments; if you are on a Daily chart, it will switch to much larger intervals (like Weekly or Monthly).

Visual Organization To keep the chart clean and readable, the script uses different line thicknesses for each timeframe. This allows you to distinguish at a glance which line represents the long-term trend and which represents the immediate price action based on the visual weight of the lines.

Real-Time Alerts Beyond just providing a visual aid, the logic includes an automated notification system. The script constantly monitors the SuperTrend for every timeframe being displayed. If the trend flips—for example, changing from a "buy" signal to a "sell" signal—the script will:

  1. Generate an audible alert sound (if enabled in settings).
  2. Print a message in the terminal logs indicating exactly which timeframe triggered the change and in which direction.

Summary of User Experience

For a trader, this tool acts as a "command center." It removes the manual work of checking multiple charts by consolidating trend data into one view, providing visual confirmation of market momentum across different time horizons, and proactively alerting the user the moment the trend changes on any of those levels.
