Watchlist & Symbols Distribution [Daveatt]

5 nov.

TLDR;
I got bored so I just coded the TradingView watchlist interface in Pinescript :)

TLDR 2:
Sharing it open-source what took me 1 full day to code - haven't coded in Pinescript in a long time, so I'm a bit slow for now :)

█ OVERVIEW
This script offers a comprehensive market analysis tool inspired by TradingView's native watchlist interface features.
It combines an interactive watchlist with powerful distribution visualization capabilities and a performance comparison panel.
The script was developed with a focus on providing multiple visualization methods while working within PineScript's limitations.

█ DEVELOPMENT BACKGROUND
The pie chart implementation was greatly inspired by the ("Crypto Map Dashboard" script /)
adapting its circular visualization technique to create dynamic distribution charts. However, due to PineScript's 500-line limitation per script, I had to optimize the code to allow users to switch between pie chart analysis and performance comparison modes rather than displaying both simultaneously.

█ SETUP AND DISPLAY

For optimal visualization, users need to adjust the chart's display settings manually.

This involves:

Expanding the indicator window vertically to accommodate both the watchlist and graphical elements
Adjusting the Y-axis scale by dragging it to ensure proper spacing for the comparison panel grid
Modifying the X-axis scale to achieve the desired time window display
Fine-tuning these adjustments whenever switching between pie chart and comparison panel modes

These manual adjustments are necessary due to PineScript's limitations in controlling chart scaling programmatically. While this requires some initial setup, it allows users to customize the display to their preferred viewing proportions.

█ MAIN FEATURES

Distribution Analysis

The script provides three distinct distribution visualization modes through a pie chart.
Users can analyze their symbols by exchanges, asset types (such as Crypto, Forex, Futures), or market sectors.

If you can't see it well at first, adjust your chart scaling until it's displayed nicely.

Asset Types


Asset Sectors


The pie charts feature an optional 3D effect with adjustable depth and angle parameters. To enhance visual customization, four different color schemes are available: Default, Pastel, Dark, and Neon.



Each segment of the pie chart includes interactive tooltips that can be configured to show different levels of detail. Importantly, the pie chart only visualizes the distribution of selected assets (those marked with a checkmark in the watchlist), providing a focused view of the user's current interests.

Interactive Watchlist

The watchlist component displays real-time data for up to 10 user-defined symbols. Each entry shows current price, price changes (both absolute and percentage), volume metrics, and a comparison toggle.
The table is dynamically updated and features color-coded entries that correspond to their respective performance lines in the comparison chart. The watchlist serves as both an information display and a control panel for the comparison feature.



Performance Comparison
One of the script's most innovative features is its performance comparison panel.
Using polylines for smooth visualization, it tracks the 30-day performance of selected symbols relative to a 0% baseline.
The comparison chart includes a sophisticated grid system with 5% intervals and a dynamic legend showing current performance values.



The polyline implementation allows for fluid, continuous lines that accurately represent price movements, providing a more refined visual experience than traditional line plots. Like the pie charts, the comparison panel only displays performance lines for symbols that have been selected in the watchlist, allowing users to focus on their specific assets of interest.

█ TECHNICAL IMPLEMENTATION

The script utilizes several advanced PineScript features:

• Dynamic array management for symbol tracking
  
• Polyline-based charting for smooth performance visualization
  
• Real-time data processing with security calls
  
• Interactive tooltips and labels
  
• Optimized drawing routines to maintain performance
  
• Selective visualization based on user choices
  

█ CUSTOMIZATION

Users can personalize almost every aspect of the script:

• Symbol selection and comparison preferences
  
• Visual theme selection with four distinct color schemes
  
• Pie chart dimensions and positioning
  
• Tooltip information density
  
• Component visibility toggles
  

█ LIMITATIONS

The primary limitation stems from PineScript's 500-line restriction per script.
This constraint necessitated the implementation of a mode-switching system between pie charts and the comparison panel, as displaying both simultaneously would exceed the line limit. Additionally, the script relies on manual chart scale adjustments, as PineScript doesn't provide direct control over chart scaling when overlay=false is enabled.
However, these limitations led to a more focused and efficient design approach that gives users control over their viewing experience.

█ CONCLUSION

All those tools exist in the native TradingView watchlist interface and they're better than what I just did.
However, now it exists in Pinescript... so I believe it's a win lol :)

Added the below in the main routine.
Otherwise, the visual elements keep repeating themselves after every new candle
