# Data Stream Monitor
|
||||
|
||||
A comprehensive system for capturing and streaming all model input data in console-friendly text format, suitable for snapshots, training, and replay functionality.
|
||||
|
||||
## Overview
|
||||
|
||||
The Data Stream Monitor captures real-time data flows through the trading system and outputs them in two formats:
|
||||
- **Detailed**: Human-readable format with clear sections
|
||||
- **Compact**: JSON format for programmatic processing
|
||||
|
||||
## Data Streams Captured
|
||||
|
||||
### Market Data
|
||||
- **OHLCV Data**: Multi-timeframe candlestick data (1m, 5m, 15m)
|
||||
- **Tick Data**: Real-time trade ticks with price, volume, and side
|
||||
- **COB Data**: Consolidated Order Book snapshots with imbalance and spread metrics
|
||||
|
||||
### Model Data
|
||||
- **Technical Indicators**: RSI, MACD, Bollinger Bands, etc.
|
||||
- **Model States**: Current state vectors for each model (DQN, CNN, RL)
|
||||
- **Predictions**: Recent predictions from all active models
|
||||
- **Training Experiences**: State-action-reward tuples from RL training
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Start the Dashboard
|
||||
```bash
|
||||
source venv/bin/activate
|
||||
python run_clean_dashboard.py
|
||||
```
|
||||
|
||||
### 2. Start Data Streaming
|
||||
```bash
|
||||
python data_stream_control.py start
|
||||
```
|
||||
|
||||
### 3. Control Streaming
|
||||
```bash
|
||||
# Check status
|
||||
python data_stream_control.py status
|
||||
|
||||
# Switch to compact format
|
||||
python data_stream_control.py compact
|
||||
|
||||
# Save current snapshot
|
||||
python data_stream_control.py snapshot
|
||||
|
||||
# Stop streaming
|
||||
python data_stream_control.py stop
|
||||
```
|
||||
|
||||

```
|

|
||||
## Files
|
||||
|
||||
### Core Components
|
||||
- `data_stream_monitor.py` - Main streaming engine
|
||||
- `data_stream_control.py` - Command-line control interface
|
||||
- `demo_data_stream.py` - Usage examples and demo
|
||||
|
||||
### Integration Points
|
||||
- `run_clean_dashboard.py` - Auto-initializes streaming
|
||||
- `core/orchestrator.py` - Provides prediction data
|
||||
- `NN/training/enhanced_realtime_training.py` - Provides training data
|
||||
|
||||
## Configuration
|
||||
|
||||
The streaming system is configurable via the `stream_config` dictionary:
|
||||
|
||||
```python
|
||||
stream_config = {
|
||||
'console_output': True, # Enable/disable console output
|
||||
'compact_format': False, # Use compact JSON format
|
||||
'include_timestamps': True, # Include timestamps in output
|
||||
'filter_symbols': ['ETH/USDT'], # Symbols to monitor
|
||||
'sampling_rate': 1.0 # Sampling rate in seconds
|
||||
}
|
||||
```
|
||||
|
||||
## Use Cases
|
||||
|
||||
### Training Data Collection
|
||||
- Capture real market conditions during training
|
||||
- Build datasets for offline model validation
|
||||
- Replay specific market scenarios
|
||||
|
||||
### Debugging and Monitoring
|
||||
- Monitor model input data in real-time
|
||||
- Debug prediction inconsistencies
|
||||
- Validate data pipeline integrity
|
||||
|
||||
### Snapshot and Replay
|
||||
- Save complete system state for later analysis
|
||||
- Replay specific time periods
|
||||
- Compare model behavior across different market conditions
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Data Collection
|
||||
- **Thread-safe**: Uses separate thread for data collection
|
||||
- **Memory-efficient**: Configurable buffer sizes with automatic cleanup
|
||||
- **Error-resilient**: Continues streaming even if individual data sources fail
|
||||
|
||||
### Integration
|
||||
- **Non-intrusive**: Doesn't affect main trading system performance
|
||||
- **Optional**: Can be disabled without affecting core functionality
|
||||
- **Extensible**: Easy to add new data streams
|
||||
|
||||
### Performance
|
||||
- **Low overhead**: Minimal CPU and memory usage
|
||||
- **Configurable sampling**: Adjust sampling rate based on needs
|
||||
- **Efficient storage**: Circular buffers prevent memory leaks
|
||||
|
||||
## Command Reference
|
||||
|
||||
| Command | Description |
|
||||
|---------|-------------|
|
||||
| `start` | Start data streaming |
|
||||
| `stop` | Stop data streaming |
|
||||
| `status` | Show current status and buffer sizes |
|
||||
| `snapshot` | Save current data snapshot to file |
|
||||
| `compact` | Switch to compact JSON format |
|
||||
| `detailed` | Switch to detailed human-readable format |
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Streaming Not Starting
|
||||
- Ensure dashboard is running first
|
||||
- Check that venv is activated
|
||||
- Verify data_stream_monitor.py is in project root
|
||||
|
||||
### No Data Output
|
||||
- Check streaming status with `python data_stream_control.py status`
|
||||
- Verify market data is available (check dashboard logs)
|
||||
- Ensure models are active and making predictions
|
||||
|
||||
### Performance Issues
|
||||
- Reduce sampling rate in stream_config
|
||||
- Switch to compact format for less output
|
||||
- Decrease buffer sizes if memory is limited
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- **File output**: Save streaming data to rotating log files
|
||||
- **WebSocket output**: Stream data to external consumers
|
||||
- **Compression**: Automatic compression for long-term storage
|
||||
- **Filtering**: Advanced filtering based on market conditions
|
||||
- **Metrics**: Built-in performance metrics and statistics
