What happened — and what it teaches
In June 2018, Portugal's PSI-20 index entered a demanding period as European equity markets faced mounting headwinds. Over the next seven months, from 2018-06-05 to 2019-01-03, traders and investors tracked a market in correction mode—a 150-bar journey through declining valuations and heightened uncertainty. The stakes were clear: navigate a sustained downtrend without compounding losses or abandoning disciplined risk management.
The index fell from 5,584.67 to 4,746.06, representing a 15.0% decline across those 150 daily bars. The maximum drawdown of 19.3% tested even patient strategies, while the largest single-day move of 2.2% showed that panic spikes remained relatively contained. Across 11 decision points—4 deemed critical—participants faced repeated choices about position sizing, stop-loss discipline, and whether to add, hold, or reduce exposure in a falling market.
This replay hones decision training by exposing participants to the psychological pressures of prolonged decline. The gap between a 15.0% loss and a 19.3% drawdown illustrates how timing and exits define real-world outcomes. Navigating 11 decision points with 4 critical junctures forces traders to confront confirmation bias and the temptation to average down. The lesson: surviving a 19.3% drawdown with a clear process matters more than capturing every rally in a 15.0% downtrend.
