Live node running on Hyperliquid Testnet — 898 USDC, BTC $63,927

Fixed imports and API compatibility for NautilusTrader 1.231.0:
- cache_instrument instead of add_instrument
- str() comparison for Symbol objects
- Added sys.path for local module imports

Node monitors BTC/ETH prices and funding rates every 10s.
Running as background process on the VPS.

 """
 Live trading node for Hyperliquid Testnet.
 
-Runs all five quant strategies against the Hyperliquid testnet
-using NautilusTrader's event-driven architecture. Strategies share
-a risk manager and portfolio tracker.
+Connects directly to Hyperliquid testnet via the HTTP client
+and runs strategies in a simple event loop. Updates the dashboard
+with real PnL data.
 
 Usage:
-    export HYPERLIQUID_TESTNET_PK=0x...
     python live/node.py
