Vasily.onl a969defe1f 3.4 -2.0 Indicator Layer System Implementation 
Implement modular chart layers and error handling for Crypto Trading Bot Dashboard

- Introduced a comprehensive chart layer system in `components/charts/layers/` to support various technical indicators and subplots.
- Added base layer components including `BaseLayer`, `CandlestickLayer`, and `VolumeLayer` for flexible chart rendering.
- Implemented overlay indicators such as `SMALayer`, `EMALayer`, and `BollingerBandsLayer` with robust error handling.
- Created subplot layers for indicators like `RSILayer` and `MACDLayer`, enhancing visualization capabilities.
- Developed a `MarketDataIntegrator` for seamless data fetching and validation, improving data quality assurance.
- Enhanced error handling utilities in `components/charts/error_handling.py` to manage insufficient data scenarios effectively.
- Updated documentation to reflect the new chart layer architecture and usage guidelines.
- Added unit tests for all chart layer components to ensure functionality and reliability.

Task 3.4: Modular Chart Layers System

Overview

Implementation of a flexible, strategy-driven chart system that supports technical indicator overlays, subplot management, and future bot signal integration. This system will replace the basic chart functionality with a modular architecture that can adapt to different trading strategies and their specific indicator requirements.

Notes

  • The modular design allows each chart layer to be tested independently
  • Strategy configurations are JSON-based for easy modification without code changes
  • Integration with existing data/common/indicators.py for technical indicator calculations
  • Backward compatibility maintained with existing components/charts.py API
  • Use uv run pytest tests/test_chart_*.py to run chart-specific tests
  • create documentation with importand components in ./docs/components/charts/ folder without redundancy
