Phase 4: Advanced Technical Indicators Management

Implemented comprehensive indicator management system for traders:

Backend (indicators.py):
- GET /api/indicators/available: All available indicators by category
- GET /api/indicators/categories: List of indicator categories
- GET /api/indicators/category/{category}: Indicators in specific category
- GET /api/indicators/{indicator_id}: Detailed indicator information
- GET /api/indicators/default: Recommended setup for gold trading
- GET /api/indicators/presets: 5 pre-configured trading setups
- POST /api/indicators/preset/{preset_id}/apply: Apply preset configuration
- POST /api/indicators/custom: Create custom indicator configuration
- GET /api/indicators/recommendations: Market condition-based recommendations
- POST /api/indicators/calculate/{indicator}: Calculate indicator values
- GET /api/indicators/alerts/golden-cross: Golden cross alerts
- GET /api/indicators/alerts/death-cross: Death cross alerts
- GET /api/indicators/alerts/divergence: Price/indicator divergence alerts
- GET /api/indicators/cheat-sheet: Quick reference guide

Indicator Categories:
1. Moving Averages: SMA, EMA, WMA with multiple periods
2. Oscillators: RSI, Stochastic, MACD, KDJ
3. Volatility: Bollinger Bands, ATR, Keltner Channels
4. Support/Resistance: Pivot Points, Fibonacci Retracement
5. Volume: OBV, CMF, Volume Profile

Pre-configured Presets:
- Scalping Setup (1-5 min): EMA 5/10, RSI, MACD, BB
- Swing Trading Setup (4h-1D): SMA 50/200, RSI, MACD, Pivot
- Position Trading Setup (1D+): SMA 50/200, RSI, BB, Fibonacci
- Volatility Focus: BB, ATR, Keltner Channel, OBV
- Momentum Focus: RSI, Stochastic, MACD, KDJ

Features:
- Market condition recommendations (trending/ranging/volatile/calm)
- Timeframe-specific setups (scalping/swing/position)
- Quick reference cheat sheet for all indicators
- Signal alerts: Golden/Death Cross, Divergences
- Indicator calculation engine for backtesting

Frontend (AdvancedIndicatorsPanel.tsx):
- Three main tabs: Presets, Custom Setup, Quick Guide
- Preset selector with one-click application
- Custom indicator builder with drag-select
- Category-based organization
- Type-based color coding
- Indicator details and parameters
- Selected indicators summary
- Pro tips and best practices
- Legend for indicator types

Integration:
- Added Indicators tab to main navigation
- Full TypeScript support
- Responsive layout for all screen sizes
- Real-time preset switching
- Custom configuration persistence

Trading Presets Include:
- Setup recommendations for different timeframes
- Indicator period suggestions
- Signal confirmation rules
- Best practices for each trading style

Note: Backend uses mock calculations. In production, integrate with:
- TA-Lib for technical analysis
- Real-time price data feeds
- WebSocket for live indicator calculations

+          <li>✓ Use 2-3 indicators maximum to avoid signal conflicts</li>
+          <li>✓ Combine different indicator types (trend + momentum + volatility)</li>
+          <li>✓ Scalping: Use fast periods (5, 10, 14)</li>
+          <li>✓ Swing/Position: Use standard periods (20, 50, 200)</li>
+          <li>✓ Always confirm signals with price action and volume</li>
+          <li>✓ Use presets as a starting point, customize based on your style</li>
