- Removed unused configuration for daily data and consolidated minute configuration into a single config dictionary. - Updated plotting logic to dynamically handle different strategies, ensuring appropriate bands and signals are displayed based on the selected strategy. - Improved error handling and logging for missing data in plots. - Enhanced the Bollinger Bands and RSI classes to support adaptive parameters based on market regimes, improving flexibility in strategy execution. - Added new CryptoTradingStrategy with multi-timeframe analysis and volume confirmation for better trading signal accuracy. - Updated documentation to reflect changes in strategy implementations and configuration requirements.
