# BBRS Incremental Strategy - Real-time Implementation

## Overview

The BBRS (Bollinger Bands + RSI) Incremental Strategy is a production-ready implementation that combines Bollinger Bands and RSI indicators with market regime detection for real-time trading. This implementation accepts minute-level data and internally aggregates to configurable timeframes while maintaining constant memory usage.

## Key Features

### 🚀 Real-time Processing
- **Minute-level Data Input**: Accepts live minute-level OHLCV data
- **Internal Timeframe Aggregation**: Automatically aggregates to configured timeframes (15min, 1h, etc.)
- **Constant Memory Usage**: O(1) memory complexity regardless of data volume
- **Fast Updates**: Sub-millisecond indicator updates

### 📊 Market Regime Detection
- **Trending Markets**: High volatility periods (BB width >= threshold)
- **Sideways Markets**: Low volatility periods (BB width < threshold)
- **Adaptive Parameters**: Different strategies for each market regime

### 🎯 Signal Generation
- **Regime-Specific Logic**: Different buy/sell conditions for trending vs sideways markets
- **Volume Analysis**: Volume spike detection and moving averages
- **Risk Management**: Built-in filters and confirmation signals

## Implementation Architecture

### Core Components

1. **BBRSIncrementalState**: Main strategy class
2. **TimeframeAggregator**: Handles real-time data aggregation
3. **BollingerBandsState**: Incremental Bollinger Bands calculation
4. **RSIState**: Incremental RSI calculation with Wilder's smoothing
5. **Volume Analysis**: Moving averages and spike detection

### Data Flow

```
Minute Data → TimeframeAggregator → Complete Bar → Indicators → Regime Detection → Signals
```

## Configuration

### Basic Configuration
```python
config = {
    "timeframe_minutes": 60,  # Target timeframe (1 hour)
    "bb_period": 20,          # Bollinger Bands period
    "rsi_period": 14,         # RSI period
    "bb_width": 0.05,         # Market regime threshold
    
    # Trending market parameters
    "trending": {
        "bb_std_dev_multiplier": 2.5,
        "rsi_threshold": [30, 70]
    },
    
    # Sideways market parameters
    "sideways": {
        "bb_std_dev_multiplier": 1.8,
        "rsi_threshold": [40, 60]
    },
    
    "SqueezeStrategy": True   # Enable volume filters
}
```

### Timeframe Options
- **1min**: Direct minute-level processing
- **5min**: 5-minute bars from minute data
- **15min**: 15-minute bars from minute data
- **30min**: 30-minute bars from minute data
- **1h**: 1-hour bars from minute data

## Usage Examples

### Real-time Trading
```python
from cycles.IncStrategies.bbrs_incremental import BBRSIncrementalState

# Initialize strategy
strategy = BBRSIncrementalState(config)

# Process live data stream
for minute_data in live_data_stream:
    result = strategy.update_minute_data(
        timestamp=minute_data['timestamp'],
        ohlcv_data={
            'open': minute_data['open'],
            'high': minute_data['high'],
            'low': minute_data['low'],
            'close': minute_data['close'],
            'volume': minute_data['volume']
        }
    )
    
    if result is not None:  # Complete timeframe bar formed
        if result['buy_signal']:
            execute_buy_order(result)
        elif result['sell_signal']:
            execute_sell_order(result)
```

### Backtesting with Pre-aggregated Data
```python
# For testing with pre-aggregated data
for timestamp, row in hourly_data.iterrows():
    result = strategy.update({
        'open': row['open'],
        'high': row['high'],
        'low': row['low'],
        'close': row['close'],
        'volume': row['volume']
    })
    
    # Process signals...
```

## Signal Logic

### Sideways Market (Mean Reversion)
```python
# Buy Conditions
buy_signal = (
    price <= lower_band and 
    rsi <= rsi_low and
    volume_contraction  # Optional with SqueezeStrategy
)

# Sell Conditions  
sell_signal = (
    price >= upper_band and
    rsi >= rsi_high and
    volume_contraction  # Optional with SqueezeStrategy
)
```

### Trending Market (Breakout Mode)
```python
# Buy Conditions
buy_signal = (
    price < lower_band and
    rsi < 50 and
    volume_spike
)

# Sell Conditions
sell_signal = (
    price > upper_band and
    rsi > 50 and
    volume_spike
)
```

## Performance Metrics

## Integration with Existing Systems

### StrategyTrader Integration
```python
# Replace existing BBRS strategy with incremental version
from cycles.IncStrategies.bbrs_incremental import BBRSIncrementalState

# Initialize in StrategyTrader
strategy = BBRSIncrementalState(config)

# Process real-time data
for data_point in real_time_feed:
    result = strategy.update_minute_data(data_point['timestamp'], data_point)
    if result and (result['buy_signal'] or result['sell_signal']):
        process_signal(result)
```

### Backtesting Integration
```python
# Use with existing backtesting framework
strategy = BBRSIncrementalState(config)

for timestamp, row in historical_data.iterrows():
    result = strategy.update(row.to_dict())
    # Process results...
```

## Troubleshooting

### Common Issues

1. **Warm-up Period**: Strategy needs sufficient data to warm up indicators
   - Solution: Ensure at least 40+ data points before expecting reliable signals

2. **Timeframe Alignment**: Minute data must align with timeframe boundaries
   - Solution: TimeframeAggregator handles this automatically

3. **Signal Differences**: Minor differences during warm-up period
   - Solution: This is expected and normal; signals converge after warm-up

### Debug Mode
```python
# Enable detailed logging
import logging
logging.basicConfig(level=logging.DEBUG)

# Check indicator states
for name, indicator in strategy.get_state_summary()['indicators'].items():
    print(f"{name}: warmed_up={indicator['is_warmed_up']}")
```
