# Universal Data Stream Architecture Audit & Optimization Plan
|
||||
|
||||
## 📊 UNIVERSAL DATA FORMAT SPECIFICATION
|
||||
|
||||
Our trading system is built around **5 core timeseries streams** that provide a standardized data format to all models:
|
||||
|
||||
### Core Timeseries (The Sacred 5)
|
||||
1. **ETH/USDT Ticks (1s)** - Primary trading pair real-time data
|
||||
2. **ETH/USDT 1m** - Short-term price action and patterns
|
||||
3. **ETH/USDT 1h** - Medium-term trends and momentum
|
||||
4. **ETH/USDT 1d** - Long-term market structure
|
||||
5. **BTC/USDT Ticks (1s)** - Reference asset for correlation analysis
|
||||
|
||||
### Data Format Structure
|
||||
```python
|
||||
@dataclass
|
||||
class UniversalDataStream:
|
||||
eth_ticks: np.ndarray # [timestamp, open, high, low, close, volume]
|
||||
eth_1m: np.ndarray # [timestamp, open, high, low, close, volume]
|
||||
eth_1h: np.ndarray # [timestamp, open, high, low, close, volume]
|
||||
eth_1d: np.ndarray # [timestamp, open, high, low, close, volume]
|
||||
btc_ticks: np.ndarray # [timestamp, open, high, low, close, volume]
|
||||
timestamp: datetime
|
||||
metadata: Dict[str, Any]

└─────────────────┴─────────────────┴─────────────────┘
|
||||
```
|
||||
|
||||
### Registered Consumers
|
||||
1. **Trading Dashboard** - UI data updates (`ticks`, `ohlcv`, `ui_data`)
|
||||
2. **Enhanced Orchestrator** - NN decision making (`training_data`, `ohlcv`)
|
||||
3. **CNN Models** - Pattern recognition (formatted CNN data)
|
||||
4. **RL Models** - Action learning (state vectors)
|
||||
5. **COB Integration** - Order book analysis (microstructure data)
|
||||
|
||||
## 🔍 ARCHITECTURE AUDIT FINDINGS
|
||||
|
||||
### ✅ STRENGTHS
|
||||
1. **Standardized Format**: All models receive consistent data structure
|
||||
2. **Publisher-Subscriber**: Efficient one-to-many data distribution
|
||||
3. **Performance Tracking**: Built-in metrics and monitoring
|
||||
4. **Multi-Timeframe**: Comprehensive temporal view
|
||||
5. **Real-time Processing**: Live data with proper buffering
|
||||
|
||||
### ⚠️ OPTIMIZATION OPPORTUNITIES
|
||||
|
||||
#### 1. **Memory Efficiency**
|
||||
- **Issue**: Multiple data copies across consumers
|
||||
- **Impact**: High memory usage with many subscribers
|
||||
- **Solution**: Implement shared memory buffers with copy-on-write
|
||||
|
||||
#### 2. **Processing Latency**
|
||||
- **Issue**: Sequential processing in some callbacks
|
||||
- **Impact**: Delays in real-time decision making
|
||||
- **Solution**: Parallel consumer notification with thread pools
|
||||
|
||||
#### 3. **Data Staleness**
|
||||
- **Issue**: No real-time freshness validation
|
||||
- **Impact**: Models might use outdated data
|
||||
- **Solution**: Timestamp-based data validity checks
|
||||
|
||||
#### 4. **Network Optimization**
|
||||
- **Issue**: Individual API calls for each timeframe
|
||||
- **Impact**: Rate limiting and bandwidth waste
|
||||
- **Solution**: Batch requests and intelligent caching
|
||||
|
||||
## 🚀 OPTIMIZATION IMPLEMENTATION PLAN
|
||||
|
||||
### Phase 1: Memory Optimization
|
||||
```python
|
||||
# Implement shared memory data structures
|
||||
class SharedDataBuffer:
|
||||
def __init__(self, max_size: int):
|
||||
self.data = np.zeros((max_size, 6), dtype=np.float32) # OHLCV + timestamp
|
||||
self.write_index = 0
|
||||
self.readers = {} # Consumer ID -> last read index
|
||||
|
||||
def write(self, new_data: np.ndarray):
|
||||
# Atomic write operation
|
||||
self.data[self.write_index] = new_data
|
||||
self.write_index = (self.write_index + 1) % len(self.data)
|
||||
|
||||
def read(self, consumer_id: str, count: int) -> np.ndarray:
|
||||
# Return data since last read for this consumer
|
||||
last_read = self.readers.get(consumer_id, 0)
|
||||
data_slice = self._get_data_slice(last_read, count)
|
||||
self.readers[consumer_id] = self.write_index
|
||||
return data_slice
|
||||
```
