A sequence, not a shortcut

Risk & strategy
learning path.

From a position size to an evidence-based process. Work through 18 lessons in order, or return to the stage that needs more attention.

The risk learning path connects a loss budget, a range of uncertain outcomes and an evidence-based review.
STAGE 01

Get the mechanics right

Build a vocabulary you can use without hiding behind it.

  1. Position sizing: start with the loss Beginner · 6 min
  2. Orders, stops and the price you actually get Beginner · 6 min
  3. Read charts without inventing certainty Beginner · 5 min
  4. Probability, expectancy and losing streaks Intermediate · 5 min
  5. Backtesting without self-deception Intermediate · 5 min
  6. Build a journal that tells the truth Beginner · 5 min
Pause and applyExplain the last two lessons to someone who has never traded. Identify one simplification in each example.
STAGE 02

Connect the moving parts

Bring product structure, costs and decisions into the same explanation.

  1. Correlation, concentration and drawdowns Intermediate · 5 min
  2. Create a complete paper-trading plan Beginner · 6 min
  3. Kelly sizing: the fragile bridge from edge to exposure Advanced · 8 min
  4. Stress tests: model the chain of failure Advanced · 8 min
  5. Walk-forward validation: keep tomorrow out of training Advanced · 8 min
  6. Portfolio risk: what the weights conceal Advanced · 8 min
Pause and applyWrite a scenario where the apparent opportunity disappears after costs, constraints or an adverse price move. State the numbers and the assumptions separately.
STAGE 03

Challenge the comfortable assumptions

Study the situations where a simple model or confident narrative breaks down.

  1. Regime shifts: adapting without chasing every wobble Advanced · 8 min
  2. Implementation shortfall: account for the decision you could not fill Advanced · 8 min
  3. Multiple testing: when the best backtest is a lucky accident Advanced · 8 min
  4. Tail risk: what VaR leaves beyond the threshold Advanced · 8 min
  5. Risk budgets: allocate uncertainty, not just dollars Advanced · 8 min
  6. Strategy capacity: when a small edge cannot absorb a large order Advanced · 8 min
Pause and applyWrite a testable rule, an invalidation condition and a loss scenario. Decide how you will detect a failed hypothesis without changing the test after seeing the answer.
Completion means you have read the material, not that a product is suitable or that you are ready to trade. Use the practice lab before adding real-world stakes.

Check the rule, the account and the evidence

Keep three records together: the decision rule, the account calculation and the evidence used to justify the rule. A correctly sized position can still belong to an unprofitable process. Conversely, an attractive historical average does not remove gaps, correlated losses or a cash deadline. Ask which of these three questions each lesson actually answers.

Use one hypothetical plan across the stages. If planned loss is 100 and execution produces a loss of 140, preserve both figures and explain the extra 40; do not redefine the original budget after the event. Write the condition for pausing the experiment before seeing its results. Later improvements create a new version to test, not retroactive evidence that the first version worked.
