What happened — and what it teaches
Between August 1997 and March 1998, the Straits Times Index entered one of the most punishing stretches in its modern history. A regional currency crisis was spreading across Asia, capital was fleeing emerging markets, and Singapore equities sat at the centre of the storm. The replay compresses that arc into 144 daily bars, asking a single question of every participant: when the ground is sliding beneath your feet, how do you decide?
Over the simulated window, the index closed at 1875.4 and finished at 1577.8, a headline decline of 15.9%. That number, however, hides the real test. The intra-period maximum drawdown reached 45.1%, meaning any moment of complacency could have meant sitting through a near halving of portfolio value. Volatility was equally unforgiving: the largest single-bar move was 13.7%, a reminder that in crisis regimes one day's "news" can be larger than a quarter of normal trading. Twenty-five decision points are scattered through the timeline, nine of them flagged as critical, where process mattered more than prediction.
What this replay teaches is fundamentally about behaviour under pressure. The crisis rewarded traders who pre-defined exits, respected position sizing, and refused to chase recovering prices after sharp one-day spikes of 13.7%. It punished those who anchored to pre-crisis levels, averaged down without a thesis, or treated drawdowns of 45.1% as temporary inconveniences rather than regime changes. The lesson is not that anyone could have called the bottom, but that disciplined frameworks — written before the panic — convert chaos into a learnable sequence of choices. In training mode, the value lies in rehearsing that discipline until it becomes reflex.
