What happened — and what it teaches
The KOSPI 200 entered a correction phase at the end of 2021, as the market shifted from a bullish run into a pullback that lasted from 28 December 2021 to 27 January 2022. The data set spans 42 daily bars from 13 December 2021 to 16 February 2022, giving participants a clear window of the downturn to study. Eight decision points were embedded, three of which were flagged as critical, forcing traders to confront timing, position sizing and risk management under rising uncertainty.
Over that stretch the index fell from a close of 39,735 to 37,175, a decline of –6.4 %. The pull‑back was not a straight line; the maximum drawdown reached 12.2 %, and the largest single‑day swing hit 3.5 %, highlighting intraday volatility that could quickly erode a position. These numbers define the market’s behavior and provide the quantitative backdrop against which each simulated choice is judged.
Trading this replay teaches how disciplined process, strict risk controls and emotional composure interact during a correction. With eight decision points and three critical junctures, participants must decide when to cut losses, add exposure, or stand aside, all while keeping the 12.2 % drawdown ceiling in mind. The 3.5 % single‑bar moves remind traders that volatility can spike without warning, reinforcing the need for a clear plan and the psychological resilience to stick to it when the market is moving against you.
