22.1 Core Insights Summary
Five Most Important Insights
| # | Insight | Source | Why Important |
|---|---|---|---|
| 1 | Prediction ≠ Profit | Lessons 9, 10 | Good predictions can lose money due to costs, execution, risk control |
| 2 | One model cannot excel in all markets | Lessons 1, 11 | This is the fundamental reason for multi-agent |
| 3 | Risk control must be independent with veto power | Lesson 15 | LTCM and countless cases prove this |
| 4 | Backtest ≠ Live trading | Lesson 7 | Backtest is just a filter, not an oracle |
| 5 | Systems decay, must evolve | Lesson 17 | Static systems have finite lifespan |
Multi-Agent Mental Model
Not "one omnipotent model," but "expert collaboration"
+-------------------------------------------------------------+
| |
| Problem Decomposition -> Expert Division -> Coordinated |
| Decision -> Unified Execution |
| |
| Regime Signal Risk Execution |
| Agent Agent Agent Agent |
| |
| "What "What "Is this "Execute this |
| market should safe?" trade optimally" |
| is this?" we do?" |
| |
+-------------------------------------------------------------+
Key Formulas Review
| Formula | Meaning | Lesson |
|---|---|---|
| Live Return = Strategy Return - Cost - Slippage - Impact | Costs determine if you can profit | Lessons 2, 18, 19 |
| Kelly: f = (pb - q) / b* | Optimal position depends on win rate and odds | Lesson 15 |
| IC = corr(Prediction, Actual) | Information coefficient measures prediction quality | Lesson 9 |
| Sharpe = (Return - Risk-free) / Volatility | Risk-adjusted return | Lesson 3 |
| Net Value = Return Improvement - Switching Cost | Evaluate Regime Detection value | Lesson 12 |
22.2 Common Misconceptions Checklist
After completing this course, you should not make these mistakes:
| Misconception | Correct Understanding | Lesson |
|---|---|---|
| "50% annual backtest return means live profit for sure" | Backtest is just a filter, must deduct costs, pass OOS | Lesson 7 |
| "60% model accuracy is impressive" | Accuracy doesn't equal profit, need IC and costs | Lesson 9 |
| "Deep learning must be better than simple models" | Complex models overfit easier, start simple | Lesson 9 |
| "Diversification means buying many stocks" | Highly correlated stocks aren't true diversification | Lesson 16 |
| "Stop-losses reduce returns" | Not stopping can reduce principal | Lesson 15 |
| "Strategy done, no need to manage" | Markets change, strategies must evolve | Lesson 17 |
| "LLM can trade directly" | LLM is a research assistant, not a trader | Lesson 14 |
| "Code runs, that's enough" | Runs ≠ reliable, operations is part of the system | Lesson 20 |
LLM Boundary: What It Can and Cannot Do
The misconception that "LLM can trade directly" deserves explicit boundaries. LLMs are powerful research tools, but they must never sit in the execution path:
| LLM CAN | LLM CANNOT |
|---|---|
| Parse 10-K filings for litigation risk | Generate trading orders |
| Detect management tone changes in earnings calls | Calculate position sizes |
| Flag accounting irregularities in financial statements | Modify risk parameters |
| Generate factor hypotheses (AlphaAgent) | Execute trades |
| Summarize macro research across multiple sources | Make real-time latency-sensitive decisions |
| Identify regime-relevant news events | Replace quantitative risk models |
Design Principle: LLM outputs are inputs to human review or to deterministic agents, never direct actuators. An LLM can suggest that a 10-K filing contains unusual litigation language, but the Risk Agent -- running deterministic, auditable code -- decides whether to adjust exposure. This separation is not optional; it is a safety boundary.

22.4 Advanced Paths
Path One: Technical Depth
If you want to go deeper in technology:
| Direction | Learning Content | Recommended Resources |
|---|---|---|
| High-Frequency Trading | Market microstructure, order book analysis, latency optimization | Trading and Exchanges by Harris |
| Deep Learning | Transformers, time series prediction, reinforcement learning | Deep Learning for Finance |
| System Architecture | Distributed systems, low-latency design | Open source project source code |
| Data Engineering | Real-time stream processing, large-scale backtesting | Kafka, Spark documentation |
Production Benchmarks: Learning vs. Production Targets
Before pursuing technical depth, understand the performance gap between a learning project and a production system:
| Metric | Learning Project | Production Target |
|---|---|---|
| Risk check latency | ~10ms (Python) | <1ms (Rust) |
| Order submission | ~100ms (REST) | <10ms (gRPC) |
| Backtest speed | Minutes/year | Seconds/year |
| Fill rate | N/A (simulated) | >94% |
| Data freshness | End-of-day (Yahoo) | Real-time L1/L2 |
| Uptime | Manual start/stop | 99.9% automated |
These gaps are not reasons to despair -- they are a roadmap. The learning project from Lesson 21 validates your strategy logic. Closing the performance gap is an engineering effort that follows validated strategy, not the other way around.
Path Two: Strategy Research
If you want to go deeper in strategy:
| Direction | Learning Content | Recommended Resources |
|---|---|---|
| Factor Investing | Multi-factor models, factor mining, factor decay | Quantitative Equity Portfolio Management |
| Derivatives | Options pricing, volatility trading, Greeks | Options, Futures, and Other Derivatives |

22.6 Final Advice
About Risk
You will lose money. The question is only how much, and whether you can learn from it.
- First live trading losses are tuition, not failure
- Control single-trade losses to give yourself enough learning opportunities
- Never use money you can't afford to lose
About Complexity
The best systems are often not the most complex.
- Start simple, add complexity only after doing simple things well
- For every component added, ask yourself: Is this really necessary?
- If rules can solve it, don't use machine learning
About Patience
Quantitative trading is a marathon, not a sprint.
- Three months backtest, three months paper trading, three months small capital - at least nine months before going formal
- Strategies need time to validate, don't give up because of one or two weeks of poor performance
- Also don't increase position size because of one or two weeks of great performance
About Continuous Learning
Markets change, so must you.
- Today's effective strategy may fail tomorrow
- Continuously follow market changes and new technologies
- Stay humble, acknowledge you don't know more than you know
