Trader OS

Overview

From first principles of trading to strategy research, quant methods, portfolio management, and institutional execution. A training system for professional trading.

Trader OS is not a conventional trading course.

It does not aim to train people who merely use indicators or predict whether prices will rise or fall. It trains Professional Decision Makers and Professional Capital Allocators: people who make decisions under uncertainty, allocate risk, test their beliefs, and survive long enough for compounding to work.

An ordinary trader sees prices. An institutional trader sees the whole system: how information becomes expectations, expectations become positions, positions consume liquidity, and prices feed back into risk and capital flows.

Where to start: choose a learning path

The same curriculum offers four ways to read it, depending on your starting point. These are four routes through one body of content, each with a recommended reading mode:

The complete loop to master

  1. Observe
  2. Hypothesis
  3. Mechanism
  4. Data
  5. Signal
  6. Research
  7. Backtest
  8. Falsification
  9. Strategy
  10. Portfolio
  11. Risk
  12. Execution
  13. Attribution
  14. Review
  15. Iteration
The complete loop learners must master. After Iteration, return to Observe.

Ultimately, the course teaches this loop rather than a particular indicator. Every chapter practices one part of it.

Foundation: six phases, 36 chapters

All 36 Foundation chapters and their accompanying experiments are available. The complete chapter list follows:

Three depths, one knowledge core

Trader OS has Foundation, Advanced, and 3D teaching formats, but they are not three independent courses. They share the same knowledge graph, chapter numbering, and learning progress. What changes is the depth of content and mathematics, the interaction, and the complexity of the market.

Each concept has just one Canonical Knowledge Node. For example, the order book is TRD-MICRO-001. In Foundation it is Chapter 13; in Advanced it is a research question in execution and microstructure; in 3D it is a simulation where you can place orders in a trading hall. See Knowledge nodes.

Every chapter has the same structure

  1. Market scene
  2. Your decision
  3. Observe the result
  4. The mechanism
  5. What it is called
  6. Real markets
  7. Hands-on
  8. Change one variable

See the phenomenon first, understand the mechanism next, and learn the terminology last. After the eight steps come three depths of the same node, questions to take away, and a chapter self-test.

What this course does not do

  • It gives no investment advice and recommends no token or exchange. It teaches mechanisms and methods, not what to buy.
  • It promises no returns. Whenever profit figures appear, they train you to ask where the money comes from and who bears the risk.
  • Labs never use real money. Exercises use calculations, public data, paper trading, or this site's simulators.
