Algorithmic Trading on the CMT Exam

Algorithmic trading implements technical analysis rules systematically through computer programs. As technology transforms markets, this topic is increasingly tested on CMT Level 2 (quantitative methods) and Level 3 (integration).

For the full guide, see the CMT Exam Guide 2026.

Types of Algorithmic Strategies

Trend-Following Algorithms

  • Implement moving average crossover systems
  • Use ADX to filter trend strength
  • Apply trendline breaks as signals
  • Managed futures (CTA) funds use these extensively

Mean-Reversion Algorithms

Market-Making Algorithms

  • Provide liquidity by quoting bid and ask prices
  • Use market microstructure data
  • Profit from bid-ask spread

Execution Algorithms

  • TWAP (Time-Weighted Average Price): Execute evenly over time
  • VWAP (Volume-Weighted Average Price): Execute proportional to volume
  • Implementation Shortfall: Minimize slippage vs. decision price

Building Algorithmic Systems

The development process follows backtesting principles:

  1. Strategy design: Translate technical analysis rules into code
  2. Historical testing: Run against years of market data
  3. Optimization: Find parameter ranges that work (avoid overfitting)
  4. Walk-forward validation: Rolling out-of-sample testing
  5. Paper trading: Live simulation without real capital
  6. Live deployment: Start with small capital, scale up

Impact on Market Structure

Algorithms have fundamentally changed markets:

  • Faster execution: Millisecond-level trading
  • Tighter spreads: More efficient pricing
  • Flash crashes: Risk of cascading automated selling
  • Pattern adaptation: Patterns may work differently in algo-dominated markets
  • Volume interpretation: Much volume is algorithmic, changing traditional volume analysis
