## Understanding Spreads

The spread value indicates:
- **Lower spread** (e.g., 0.01-0.05): High liquidity, tight market
- **Higher spread** (e.g., 0.10+): Lower liquidity, wider market
- A spread of 0 indicates no active orders on one or both sides

## Use Cases

- Assess market liquidity before placing orders
- Compare trading costs across different markets
- Monitor market health and trading conditions
- Optimize order placement strategies
