How It Works
Signal Generation
The EA analyzes Bollinger Bands using multiple strategies:
- Movement Analysis: Detects significant price movements relative to BB bands
- Strength/Divergence Assessment: Identifies divergences between price and BB indicators
- Signal Strategy: Uses BB crossovers and band touches for entry signals
- Advanced Logic: Compares current bar conditions with previous bar for confirmation
- Swing Analysis: Uses lookback periods to identify significant price swings
Entry Logic
When multiple BB strategies align and pass additional filters (EMA trend, Entry Gate), the system:
- Validates all trading conditions using built-in validation system
- Checks money requirements and volume constraints
- Applies stop level validation and market hours checks
- Executes base entries or grid trades based on configuration
- Adapts grid spacing based on market regime (trending vs ranging)
Risk Management
The system continuously monitors positions and applies:
- ATR-based trailing stops for dynamic risk management
- Breakeven functionality to protect capital
- Partial close management to secure profits
- Grid stop-out protection to prevent excessive losses
- Regime-aware position sizing and grid adjustments
BB Strategies Explained
Movement Strategy
Analyzes price movement relative to Bollinger Bands to identify potential breakouts and reversals. The strategy looks for significant price movements that indicate momentum shifts.
Strength/Divergence Strategy
Identifies divergences between price action and BB indicators. This strategy uses multiple threshold methods (points-based, ATR-based) to detect meaningful divergences that may signal trend reversals.
Signals Strategy
Uses traditional BB signals such as band touches, crossovers, and squeezes to generate trading opportunities. This strategy provides classic BB trading signals with enhanced filtering.
Advanced Logic
Implements sophisticated comparison logic between current and previous bars to confirm signals and reduce false entries. This approach enhances signal quality and reliability.
