What Is Discretionary Trading and How Does It Differ from Algorithmic Trading?

Discretionary Trading

Discretionary trading is a traditional investment approach where human traders make buy and sell decisions based on their judgement, experience, and market analysis. These traders use a combination of fundamental and technical analysis to identify potential investment opportunities and execute trades manually.

Key Characteristics of Discretionary Trading

  • Human Judgment: Human traders rely on their intuition, experience, and market knowledge to make trading decisions.
  • Flexibility: Traders can adapt to changing market conditions quickly and make real-time adjustments to their strategies.
  • Qualitative Analysis: Traders often consider qualitative factors like company management, industry trends, and economic indicators in their decision-making process.
  • Subjective Decisions: Human emotions and biases can influence trading decisions, which may lead to irrational behaviour.

Algorithmic Trading

Algorithmic trading, also known as algo-trading, involves the use of computer programs to execute trading strategies automatically. These algorithms are designed to identify trading opportunities, execute trades, and manage risk based on predefined rules and parameters. Key Characteristics of Algorithmic Trading
  • Computer Algorithms: Complex algorithms analyse market data and execute trades at high speed.
  • Speed and Precision: Algorithmic trading can execute trades much faster than human traders, reducing the impact of market volatility.
  • Reduced Emotional Bias: By eliminating human emotions, algorithms can make more rational and objective decisions.
  • High-Frequency Trading (HFT): A subset of algorithmic trading that involves very high-speed trading of large quantities of securities.

How Discretionary and Algorithmic Trading Differ

Feature Discretionary Trading Algorithmic Trading
Decision-Making Human judgment Computer algorithms
Execution Speed Slower Faster
Emotional Influence Prone to emotional bias Less susceptible to emotional bias
Flexibility More flexible Less flexible but can be reprogrammed
Cost Lower implementation costs Higher initial development and maintenance costs

The Hybrid Approach

In recent years, there has been a growing trend towards a hybrid approach that combines the best of both worlds. This approach involves using algorithms to execute trades based on human-generated trading signals. This allows traders to leverage the speed and precision of algorithms while retaining the flexibility and judgment of human decision-making.

Conclusion

Both discretionary and algorithmic trading have their own advantages and disadvantages. The choice between the two depends on various factors, including the trader's risk tolerance, investment horizon, and access to advanced technology. As technology continues to evolve, it is likely that the hybrid approach will become increasingly popular, allowing traders to harness the power of both human and machine intelligence.
