UI Framework and Library

Framework: React Styling: Tailwind CSS Additional UI Libraries: Headless UI (for accessible components)

Design Philosophy

The application follows a minimalistic, modern design inspired by Apple's design language with:

• Clean, uncluttered interfaces
• Ample white space
• Subtle animations and transitions
• Focus on content and functionality
• Support for both light and dark mode

Navigation Structure

The application uses a sidebar navigation layout with the following primary sections:

1. Dashboard - Overview of user activity and saved strategies
2. Strategy Builder - Main interface for creating strategies
3. My Strategies - Library of saved and generated strategies
4. Community - Social features and shared strategies
5. Settings - Account management and preferences

Mobile view will use a collapsible hamburger menu to ensure responsiveness.

State Management

Solution: Zustand

Zustand is selected for state management due to its:

• Simplified API compared to Redux
• Strong performance for complex state
• Minimal boilerplate code
• Good compatibility with React's concurrent features
• Ability to handle complex nested state required for strategy configurations

Component Structure

Core Components

1. StrategyBuilder

   • Main component for strategy creation
   • Contains sub-sections for each framework part
   • Houses the visual indicator selection interface

2. IndicatorSelector

   • Allows selection from pre-built indicators
   • Provides customization controls for indicator parameters
   • Displays visual representation of indicator behavior

3. StrategyViewer

   • Displays the complete strategy with all selected components
   • Provides export options
   • Shows educational content about strategy components

4. CodeExporter

   • Generates PineScript code
   • Toggles between minimal and commented code
   • Provides copy functionality

5. AIStrategyGenerator

   • Interface for API key management
   • Controls for AI-based strategy generation
   • Displays generated strategies with explanations

6. StrategyVersionControl

   • Manages different versions of strategies
   • Provides comparison tools
   • Allows reverting to previous versions

Shared Components

1. Header

   • App logo and navigation
   • User profile and account menu
   • Theme toggle (light/dark mode)

2. Sidebar

   • Main navigation menu
   • Collapsible on mobile devices

3. Modal

   • Reusable modal component for alerts, confirmations, etc.

4. Toast

   • Notification system for success/error messages

5. Button

   • Consistent button styles across the application
   • Various states (primary, secondary, disabled)

6. Card

   • Container for strategy items and content blocks

Forms and Inputs

1. API Key Management Form

   • Secure input for LLM API keys
   • Validation for proper key format
   • Test connection functionality

2. Strategy Parameters Form

   • Number inputs with min/max validation
   • Toggle switches for boolean options
   • Dropdown selects for pre-defined options

3. Filter and Search Forms

   • Used in strategy library and community sections
   • Quick filtering by strategy type, performance, etc.

Responsive Design

The application will follow a mobile-first approach with specific breakpoints for:

• Mobile (< 640px)
• Tablet (640px - 1024px)
• Desktop (> 1024px)

Tailwind's responsive classes will be utilized for consistent responsive behavior.

Theme Management

The application will support both light and dark modes:

• System preference detection by default
• User toggle option
• Persistent preference storage
• Smooth transition between themes

Performance Considerations

1. Code Splitting

   • Route-based code splitting
   • Dynamic imports for heavy components

2. Lazy Loading

   • Defer loading of non-critical components
   • Implement for community features and advanced settings

3. Memoization

   • Use React.memo for complex component renders
   • Implement useMemo for expensive calculations

4. Asset Optimization

   • Optimize images and icons
   • Use SVGs where possible for crisp rendering at all sizes
