Trading and Execution
Trading and Execution refer to the processes involved in placing, managing, and completing financial transactions in capital markets. These functions are critical in ensuring that investment strategies are effectively carried out, with a focus on achieving the best possible results in terms of price, cost, and timing.
🔹 1. Trading
Trading involves the decision-making process around what to buy or sell, when, and in what quantity, based on a chosen strategy. Strategies may range from long-term investing to high-frequency trading (HFT), and can be discretionary or algorithmic.
Key trading styles include:
Market Making
Arbitrage
Trend Following
Statistical Arbitrage
Fundamental or Technical Trading
🔹 2. Execution
Execution is the actual process of carrying out the trade in the marketplace. It focuses on how to enter or exit a position efficiently while minimizing:
Market Impact
Slippage
Transaction Costs
Modern execution often uses electronic trading platforms, algorithms, and direct market access (DMA) to achieve precision and speed.
Common execution algorithms:
VWAP (Volume Weighted Average Price)
TWAP (Time Weighted Average Price)
POV (Participation of Volume)
Implementation Shortfall
Iceberg or Stealth Orders
🔹 3. Smart Order Routing (SOR)
SOR systems direct orders to the best execution venue by analyzing prices across multiple exchanges, considering liquidity, fees, and timing.
🔹 4. Risk Management in Execution
To ensure safety and compliance, risk controls are embedded into execution systems. These include:
Pre-trade risk checkssition limits
Fat-finger error protection
Compliance with regulatory requirements
🔹 5. Transaction Cost Analysis (TCA)
Post-trade evaluation through TCA helps assess the efficiency of execution strategies and highlights areas for improvement.
🔹 6. Technology in Execution
Effective trading and execution rely on:
Low latency infrastructure
Order Management Systems (OMS)
Execution Management Systems (EMS)
Broker APIs / FIX Protocol
Trading and Execution are foundational to capital markets. While trading focuses on the strategy behind market activity, execution ensures that trades are carried out efficiently, with minimal costs and in compliance with regulations. The growing use of technology and data analytics continues to shape how institutions approach both functions.
