+### Market Snapshots
+
+```python
+# Get snapshot for a single symbol
+snapshot = api.stock.snapshots.get_snapshot("AAPL")
+print(f"Latest trade: ${snapshot.latest_trade.price}")
+print(f"Latest quote: Bid ${snapshot.latest_quote.bid} / Ask ${snapshot.latest_quote.ask}")
+print(f"Daily bar: Open ${snapshot.daily_bar.open} / Close ${snapshot.daily_bar.close}")
+print(f"Previous daily: Open ${snapshot.prev_daily_bar.open} / Close ${snapshot.prev_daily_bar.close}")
+
+# Get snapshots for multiple symbols (efficient batch operation)
+symbols = ["AAPL", "GOOGL", "MSFT", "TSLA", "NVDA"]
+snapshots = api.stock.snapshots.get_snapshots(symbols)
+for symbol, snapshot in snapshots.items():
+    print(f"{symbol}: ${snapshot.latest_trade.price} ({snapshot.daily_bar.volume:,} volume)")
+
+# Get snapshots with specific feed
+snapshots = api.stock.snapshots.get_snapshots(
+    symbols=["SPY", "QQQ"],
+    feed="iex"  # or "sip", "otc"
+)
+```
+
+### Account Configuration
+
+```python
+# Get current account configuration
+config = api.trading.account.get_configuration()
+print(f"PDT Check: {config.pdt_check}")
+print(f"Trade Confirm Email: {config.trade_confirm_email}")
+print(f"Suspend Trade: {config.suspend_trade}")
+print(f"No Shorting: {config.no_shorting}")
+
+# Update account configuration
+updated_config = api.trading.account.update_configuration(
+    trade_confirm_email=True,
+    suspend_trade=False,
+    pdt_check="both",  # "both", "entry", or "exit"
+    no_shorting=False
+)
+print("Account configuration updated successfully")
+```
+
+### Market Metadata
+
+```python
+# Get condition codes for trades
+condition_codes = api.stock.metadata.get_condition_codes(tape="A")
+for code in condition_codes:
+    print(f"Code {code.code}: {code.description}")
+
+# Get exchange codes
+exchanges = api.stock.metadata.get_exchange_codes()
+for exchange in exchanges:
+    print(f"{exchange.code}: {exchange.name} ({exchange.type})")
+
+# Get all condition codes at once (cached for performance)
+all_codes = api.stock.metadata.get_all_condition_codes()
+print(f"Loaded {len(all_codes)} condition codes")
+
+# Lookup specific codes
+code_info = api.stock.metadata.lookup_condition_code("R")
+print(f"Code R means: {code_info.description}")
+```
+
+### Enhanced Order Management
+
+```python
+# Place order with client order ID for tracking
+order = api.trading.orders.market(
+    symbol="AAPL",
+    qty=1,
+    side="buy",
+    client_order_id="my-app-order-123"
+)
+
+# Replace an existing order (modify price, quantity, etc.)
+replaced_order = api.trading.orders.replace_order(
+    order_id=order.id,
+    qty=2,  # Change quantity
+    limit_price=155.00  # Add/change limit price
+)
+
+# Get order by client order ID (useful for tracking)
+orders = api.trading.orders.get_all(status="open")
+my_order = next((o for o in orders if o.client_order_id == "my-app-order-123"), None)
+
+# Advanced OCO/OTO orders
+oco_order = api.trading.orders.limit(
+    symbol="TSLA",
+    qty=1,
+    side="buy",
+    limit_price=200.00,
+    order_class="oco",  # One-Cancels-Other
+    take_profit={"limit_price": 250.00},
+    stop_loss={"stop_price": 180.00}
+)
+```
+
+### Smart Feed Management
+
+```python
+# The library automatically manages feed selection based on your subscription
+# No configuration needed - it automatically detects and falls back as needed
+
+# Manual feed configuration (optional)
+from py_alpaca_api.http.feed_manager import FeedManager, FeedConfig, FeedType
+
+# Configure preferred feeds
+feed_config = FeedConfig(
+    preferred_feed=FeedType.SIP,  # Try SIP first
+    fallback_feeds=[FeedType.IEX],  # Fall back to IEX if needed
+    auto_fallback=True  # Automatically handle permission errors
+)
+
+# The feed manager automatically:
+# - Detects your subscription level (Basic/Unlimited/Business)
+# - Falls back to available feeds on permission errors
+# - Caches failed feeds to avoid repeated attempts
+# - Provides clear logging for debugging
+```
+
+### Intelligent Caching System
+
+```python
+# Caching is built-in and automatic for improved performance
+# Configure caching (optional - sensible defaults are provided)
+from py_alpaca_api.cache import CacheManager, CacheConfig
+
+# Custom cache configuration
+cache_config = CacheConfig(
+    max_size=1000,  # Maximum items in cache
+    default_ttl=300,  # Default time-to-live in seconds
+    data_ttls={
+        "market_hours": 86400,  # 1 day
+        "assets": 3600,  # 1 hour
+        "quotes": 1,  # 1 second
+        "positions": 10,  # 10 seconds
+    }
+)
+
+# Cache manager automatically:
+# - Caches frequently accessed data
+# - Reduces API calls and improves response times
+# - Manages memory efficiently with LRU eviction
+# - Supports optional Redis backend for distributed caching
+
+# Use the @cached decorator for custom caching
+cache_manager = CacheManager(cache_config)
+
+@cache_manager.cached("custom_data", ttl=600)
+def expensive_calculation(symbol: str):
+    # This result will be cached for 10 minutes
+    return complex_analysis(symbol)
+```
