Market Simulator

Four markets, one month at a time. You get prices and a newspaper, and nothing else — no chart of what happens next, no name you could look up.

Prices are simulated and companies are fictional, calibrated so each market’s index and each company’s peak-to-trough fall match the documented figures for the real event it is modeled on. Fictional names are the point: if you could recognize the event from the tape, you would be trading with hindsight instead of judgment.

  • Practice environment
  • Not a validated instrument

You learn: What you do when a position moves against you and hindsight is unavailable — whether you add, hold, or sell, and how that changed month to month.

What the report reads off your record

What you did as it fell
Whether you added, held, or sold when a position moved against you — and whether that answer changed between the first drawdown and the fourth.
How concentrated you got
Whether conviction showed up as a large position in one company or as a spread across several, and what that cost or saved you when the market turned.
How you used the newspaper
Each month's report is the information a trader had at that node and no more. Whether you traded ahead of the news or after it is visible in the record.

10–20 minutes per scenario · no account needed. This is not a validated measure of risk tolerance and nothing here is written to your psychology profile — the money is not real, which weakens it against a study that pays in cash. For a task built as a measure, the Balloon Risk Task is the one to take.
