## 🔄 Real-time Operations

### Multi-Timeframe Real-time Data
```python
from project_x_py import create_data_manager

# Create real-time data manager
data_manager = create_data_manager(
    instrument="MGC",
    project_x=client,
    realtime_client=realtime_client,
    timeframes=["5sec", "1min", "5min", "15min"]
)

# Initialize with historical data
data_manager.initialize(initial_days=30)
data_manager.start_realtime_feed()

# Access real-time data
live_5sec = data_manager.get_data("5sec", bars=100)
live_5min = data_manager.get_data("5min", bars=50)

# Monitor memory usage
memory_stats = data_manager.get_memory_stats()
print(f"Memory usage: {memory_stats}")
```

### Advanced Order Management
```python
from project_x_py import create_order_manager

# Create order manager with real-time tracking
order_manager = create_order_manager(client, realtime_client)

# Place orders with automatic retries
market_order = order_manager.place_market_order("MGC", 0, 1)
bracket_order = order_manager.place_bracket_order(
    "MGC", 0, 1, 
    entry_price=2045.0,
    stop_price=2040.0,
    target_price=2055.0
)

# Monitor order status
orders = order_manager.search_open_orders()
for order in orders:
    print(f"Order {order.id}: {order.status}")
```

### Level 2 Market Depth Analysis
```python
from project_x_py import create_orderbook

# Create orderbook with memory management
orderbook = create_orderbook("MGC")

# Process market depth data (automatically from WebSocket)
depth_snapshot = orderbook.get_orderbook_snapshot()
best_prices = orderbook.get_best_bid_ask()

# Advanced analysis
iceberg_orders = orderbook.detect_iceberg_orders()
imbalance = orderbook.calculate_order_imbalance()

# Monitor memory usage
memory_stats = orderbook.get_memory_stats()
print(f"Orderbook memory: {memory_stats}")
```

## ⚡ Performance Optimizations

### Connection Pooling & Caching
- **HTTP Connection Pooling**: Reuses connections with automatic retries
- **Instrument Caching**: Eliminates repeated API calls for contract data
- **Preemptive Token Refresh**: Prevents authentication delays
- **Session Management**: Persistent sessions with connection pooling

### Memory Management
- **Sliding Windows**: Configurable limits for all data structures
- **Automatic Cleanup**: Periodic garbage collection and data pruning
- **Memory Monitoring**: Real-time tracking of memory usage
- **Configurable Limits**: Adjust limits based on available resources

### Optimized DataFrame Operations
- **Chained Operations**: Reduce intermediate DataFrame creation
- **Lazy Evaluation**: Polars optimization for large datasets
- **Efficient Datetime Parsing**: Cached timezone operations
- **Vectorized Calculations**: Optimized mathematical operations

### Performance Monitoring
```python
# Client performance metrics
print(f"API calls made: {client.api_call_count}")
print(f"Cache hit rate: {client.cache_hit_count / client.api_call_count * 100:.1f}%")
print(client.get_health_status())

# Component memory usage
print(orderbook.get_memory_stats())
print(data_manager.get_memory_stats())

# Indicator cache statistics
for indicator in [RSI(), SMA(), EMA()]:
    print(f"{indicator.name} cache size: {len(indicator._cache)}")
```

### Expected Performance Improvements
- **50-70% reduction in API calls** through intelligent caching
- **30-40% faster indicator calculations** via optimized operations
- **60% less memory usage** through sliding window management
- **Sub-second response times** for cached operations
- **95% reduction in polling** with real-time WebSocket feeds

### Memory Limits (Configurable)
```python
# Default limits (can be customized)
orderbook.max_trades = 10000              # Trade history
orderbook.max_depth_entries = 1000        # Depth per side
data_manager.max_bars_per_timeframe = 1000 # OHLCV bars
data_manager.tick_buffer_size = 1000       # Tick buffer
indicators.cache_max_size = 100            # Indicator cache
```
