Section 1: AI vs. Traditional Trading - Key Differences

1.1 How AI Trading Actually Works

Traditional Trading	AI-Powered Trading
Manual chart analysis	Pattern recognition across 50+ indicators
Gut-feeling decisions	Backtested probability models
4-6 hour screen time	24/7 automated execution

Real Example: Hedge funds like Renaissance Technologies achieved 66% annual returns using AI (SEC filings).

1.2 Three Types of AI Used in Trading

1. Machine Learning (Price Prediction)
   • Algorithms that improve with more data
   • Example: LSTM neural networks
2. Natural Language Processing (News Trading)
   • Analyzes earnings calls, SEC filings, Twitter
   • Tools: AlphaSense, RavenPack
3. Reinforcement Learning (Strategy Optimization)
   • Self-improving systems like DeepMind's AlphaStock
   • Requires Python coding knowledge
