✨ Hybrid is the future:. AI suggests rules. Human vets them. AI makes trades within a safe sandbox. Humans monitor edge cases.

| 🧠 AI-Generated Rules vs πŸ€– Direct AI Decisions |.πŸ“‹ Quick comparison:.βœ… Human-readable vs ❌ Mostly black-box.⚠️ Learns slower, but stable vs βœ… Learns fast, but risky.πŸ§ͺ Low overfitting, great for audit vs πŸ”₯ High risk, but agile.

πŸ’‘ Real-world example:. A PPO RL agent is trained to maximize profit across crypto pairs. Every hour, it samples state β†’ action (buy/sell). Actions get scored (profit/loss). Model updates with feedback. ⚠️ Often black-box. High performance, low explainability.

The agent loop:. Receive new market data. Predict "Buy", "Sell", or "Hold". Log outcome. Retrain model over time. Improve over episodes. Sounds like AlphaGo? It is β€” but for markets. β™ŸοΈπŸ“‰πŸ“ˆ.

2️⃣ Direct AI Decisions. Here, AI is the trader. πŸ“‘ Data β†’ πŸ€– Model β†’ πŸ“ˆ Trade. Popular AI models used:. 🧠 LSTM (time-series forecasting). πŸ” PPO/DQN (reinforcement learning). πŸ“š Transformers. πŸ’¬ Claude/Grok (for news/sentiment parsing).

πŸ’‘ Real-world example:. β€œIf price is above 50-day MA and volume is rising β†’ Buy”. AI (e.g. GPT, Claude) could:. Suggest that rule based on backtesting. Rank it based on Sharpe Ratio. Tune the thresholds. The bot becomes a quant assistant πŸ§ πŸ“Š.

1️⃣ AI-Generated or Reviewed Rules. The AI suggests, but humans stay in control. πŸ”Ή AI finds edge/patterns.πŸ”Ή Converts it to logic (like RSI < 30).πŸ”Ή Human refines it.πŸ”Ή Bot trades based on this logic.βœ… Transparent.βœ… Easy to backtest.βœ… More regulation-friendly.

I believe this question is broader than AI trading, focusing on decision-making, the core purpose of programming languages: rules vs. AI decisions.
