SUMMARY

Smart Order Routing (SOR) is an automated trading technology that optimizes order execution by analyzing and accessing liquidity across multiple trading venues in real-time. SORs make dynamic routing decisions based on factors including price, liquidity, transaction costs, and venue characteristics to achieve best execution for traders.

Core functionality of Smart Order Routing

Smart Order Routing systems serve as intelligent intermediaries between traders and fragmented markets. Their primary function is to analyze available trading opportunities across multiple venues and determine optimal execution paths. This process involves:

  • Real-time market data analysis across venues
  • Price-venue arbitrage detection
  • Dynamic liquidity assessment
  • Transaction cost analysis
  • Latency-aware routing decisions

Market fragmentation and SOR strategies

SORs help traders navigate market fragmentation by implementing sophisticated routing strategies:

Liquidity aggregation

SORs aggregate liquidity across:

Price discovery optimization

The system continuously monitors and compares:

  • Displayed quotes
  • Hidden liquidity
  • Implied prices
  • Cross-market opportunities
