Data Sources & APIs Used:

• CoinGecko API: Primary data source providing comprehensive historical price data, market capitalization, trading volume, and current market metrics. The system fetches up to 14 days of historical data with daily intervals for accurate trend analysis.
• CoinPaprika API: Secondary fallback data source that provides alternative historical price data when CoinGecko data is insufficient. This ensures data reliability and continuous service availability.
• Cryptics.tech API: External prediction service that provides additional forecasting data from their proprietary analysis models, offering complementary insights to our internal calculations.
• Internal Database: Leverages existing platform data from LiveCoinWatch and CoinGecko tables for instant access to current market data, reducing API calls and improving response times.

Technical Implementation:

• Linear Regression Analysis: Implements mathematical regression models using the last 10 data points to calculate price trends and generate 7-day forward predictions with confidence intervals.
• Volatility Calculation: Computes price volatility using standard deviation analysis of the last 7 days of price data, helping users understand market risk and price stability.
• Multi-Layer Caching System: Implements intelligent caching at multiple levels - main predictions cache (10 minutes), symbol-specific cache (5 minutes), historical data cache (10 minutes), and external predictions cache (15 minutes) for optimal performance.
• Fallback Strategy: Robust error handling with automatic fallback between data sources, ensuring predictions are available even when primary APIs are temporarily unavailable.

Performance Optimizations:

• Database-First Approach: Prioritizes existing database data over API calls, reducing response times by up to 90% for frequently accessed symbols.
• Reduced API Timeouts: Implements 3-second timeout limits for external API calls to prevent page hanging and ensure responsive user experience.
• Minimal Data Requirements: Requires only 5 data points for predictions and 7 data points for volatility calculations, enabling faster processing while maintaining accuracy.
• Parallel Processing: Uses array_map for concurrent symbol data processing, reducing total calculation time for multiple cryptocurrencies.
• Browser Caching: Implements HTTP cache headers with 5-minute browser cache and ETag support for instant subsequent page loads.

Prediction Features:

• 7-Day Price Forecasts: Generates daily price predictions for the next week based on historical trend analysis and market momentum.
• Market Metrics Integration: Includes current market capitalization, 24-hour trading volume, and price volatility in prediction analysis.
• Multi-Source Validation: Compares internal predictions with external API forecasts to provide users with comprehensive market insights.
• Real-Time Updates: Predictions refresh automatically with new market data, ensuring forecasts remain relevant and accurate.
• Error Handling: Graceful degradation when external APIs are unavailable, continuing to provide internal predictions based on available data.

Note: Predictions are based on historical data analysis and mathematical models. They should be used as one of many tools in your trading strategy, not as the sole basis for investment decisions. Market conditions can change rapidly, and past performance does not guarantee future results.
