Download script
The CandleDifference indicator is designed to provide traders with a quick, real-time overview of price fluctuations across multiple currency pairs simultaneously. Instead of requiring you to manually switch between different charts to monitor various markets, this tool centralizes that information into a single display on your current screen.
How the Logic Works
The core functionality of the script can be broken down into three main steps:
1. Multi-Market Monitoring The tool is configured to track up to eight specific currency pairs at once (such as EURUSD, GBPUSD, etc.). You can define these pairs within the settings, allowing the indicator to "watch" a diverse basket of markets regardless of which chart you are currently viewing.
2. Performance Calculation For each active currency pair selected, the script looks back at the price movement relative to the opening price of a specific timeframe (for example, the Daily chart). It calculates the percentage difference between the current live market price and that opening price.
Essentially, it answers the question: "Since the start of the current day (or your chosen timeframe), by what percentage has this specific currency pair moved?"
3. Real-Time Data Display Instead of cluttering your chart with complex lines or bars, the script compiles all this data into a clean, text-based summary. This summary is displayed directly on your main chart window as a comment. It lists each currency pair followed by its current percentage change, providing an instant snapshot of market momentum across your entire portfolio of interests.
Key Benefits for the User
- Efficiency: View the health and movement of multiple pairs without clicking through dozens of tabs.
- Contextual Awareness: Quickly identify which currencies are leading the market and which are lagging in real-time.
- Clean Interface: The logic runs quietly in the background, presenting only the essential percentage data exactly where you need to see it.
