Study Notes
- Algorithmic trading uses automated, pre-programmed instructions to execute orders based on factors like price, timing, and volume.
- It is also known as automated trading, black-box trading, and algo-trading.
- Investment banks, pension funds, mutual funds, and hedge funds widely use it.
How Algorithmic Trading Works
- An algorithm is created to generate buy and sell orders based on rules.
- The algorithm is backtested using historical data to evaluate performance.
- The algorithm is deployed to a live trading account if backtesting results are satisfactory.
- The algorithm automatically generates orders.
- The trader monitors the algorithm and makes adjustments.
Types of Algorithmic Trading Strategies
- Trend Following: Algorithms that identify and follow market trends.
- Mean Reversion: Trading price fluctuations around an average price.
- Arbitrage: Exploiting price differences for the same asset in different markets.
- Statistical Arbitrage: Using statistical models to trade on market mispricings.
- Market Making: Providing liquidity by placing buy and sell orders near market price.
- Execution Algorithms: Executing large orders with minimal market impact.
Advantages of Algorithmic Trading
- Increased speed and efficiency in trade execution.
- Reduced trading costs due to automation.
- Improved accuracy by minimizing human error.
- Greater consistency by eliminating emotional decisions.
- Allows the strategy to be backtested on historical data for viability.
Disadvantages of Algorithmic Trading
- Requires technical skills to develop and maintain algorithms.
- Demands constant monitoring to ensure proper function.
- Risk of failure due to improper algorithm design or testing.
- Over-optimization can result in poor live performance.
- Algorithms need updates to adapt to changing market conditions.
High-Frequency Trading
- High-frequency trading (HFT) is a type of algorithmic trading with high speeds, turnover rates, and order-to-trade ratios.
- HFT firms use algorithms and computers to identify and exploit small price discrepancies.
- They execute a large number of orders at high speeds.
- HFT firms use co-location to minimize latency by placing servers near exchanges.
Advantages of High-Frequency Trading
- Market liquidity increases through a high volume of buy and sell orders.
- Transaction costs are reduced by narrowing bid-ask spreads.
- Market efficiency increases by identifying and exploiting price discrepancies.
Disadvantages of High-Frequency Trading
- HFT firms may gain an unfair advantage due to speed and technology.
- Algorithms can be used to manipulate the market.
- HFT can increase market volatility by amplifying price swings.
- HFT can pose a systemic risk to the market.
Key Differences
| Feature | Algorithmic Trading | High-Frequency Trading |
|---|---|---|
| Focus | Executing orders based on predefined rules and strategies | Exploiting short-term market inefficiencies at high speed |
| Speed | Not necessarily high-speed | Extremely high-speed |
| Latency Sensitivity | Less sensitive | Highly sensitive |
| Turnover Rate | Varies depending on the strategy | Very high turnover rate |
| Order-to-Trade Ratio | Lower compared to HFT | High order-to-trade ratio |
| Infrastructure | Standard trading infrastructure | Advanced infrastructure with co-location services |
| Strategies | Wide range of strategies | Typically short-term, arbitrage-based strategies |
| Market Impact | Aims for minimal impact based on strategy | Can have significant impact due to high frequency |
Conclusion
- Algorithmic and high-frequency trading are tools to improve trading but come with risks.
- Understanding their advantages and disadvantages is crucial before using them.
