This implementation includes:

1. **Trading Functions**
   - Complete Jupiter swap integration
   - Priority transaction handling
   - Position tracking
   - Trade execution with retries

2. **Market Data**
   - Price fetching
   - Volume calculation
   - Liquidity monitoring
   - Price change calculation
   - Caching mechanism

3. **Safety Features**
   - Error handling
   - Transaction validation
   - Market data validation
   - Position tracking

To use:
1. Add this to your `lib.rs` file
2. Make sure all dependencies are in your `Cargo.toml`
3. Build with:
```bash
maturin develop --release --jobs 13
```

Would you like me to:
