"""
Chart Layers Package

This package contains the modular layer system for building complex charts
with multiple indicators, signals, and subplots.

Components:
- BaseChartLayer: Abstract base class for all layers
- CandlestickLayer: OHLC price chart layer
- VolumeLayer: Volume subplot layer
- LayerManager: Orchestrates multiple layers
- SMALayer: Simple Moving Average indicator overlay
- EMALayer: Exponential Moving Average indicator overlay
- BollingerBandsLayer: Bollinger Bands overlay with fill area
- RSILayer: RSI oscillator subplot
- MACDLayer: MACD lines and histogram subplot
