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

@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]

🔍 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• Impact: Models might use outdated data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

# 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
