Event Replay
What happened — and what it teaches
The scene opens with the USD/IDR pair in the summer of 2018, as contagion from the Turkish lira crisis and Argentine peso collapse rippled across emerging-market currencies. Between August 22 and November 22, 66 daily bars capture a market trying to absorb the shock while Indonesian policymakers defended the rupiah. For traders and risk managers, this period posed a classic EM crisis test: when confidence erodes across an entire asset class, how do you size positions, manage drawdowns, and avoid panic selling at the bottom?
The data shows a modest net outcome—USD/IDR closed at 14630 on November 22, roughly 0.4% higher than the 14572 opening—yet this headline number obscures the turbulence in between. The maximum drawdown hit 5.5%, and intraday swings reached 1.8% on the most volatile bars, creating real psychological pressure. Participants faced 12 decision points, with four marked as critical, requiring them to act under uncertainty without the benefit of hindsight.
This replay is designed to train the decision process rather than predict outcomes. The 5.5% drawdown forces realistic position-sizing discussions, while the 1.8% single-bar moves test emotional discipline. With four critical junctures, learners must practice calibrating conviction against risk, distinguishing between signal and noise in a crisis environment. The goal is building the habits—systematic review, pre-defined exits, and emotional neutrality—that separate durable performers from reactive ones when markets move against them.
