What happened — and what it teaches
The USD/LKR market in the autumn of 2018 presented traders with a textbook emerging market currency crisis scenario. Sri Lanka's external position had become increasingly fragile, with foreign reserves under pressure and the central bank navigating a difficult balancing act between supporting the currency and maintaining growth. The three-month replay window from September 6 to December 7 gave participants a rare chance to experience the slow-burn tension of an EM currency under sustained attack, with 12 decision points embedded across 66 daily bars to test their conviction and timing.
Over this 66-day period the dollar climbed from 161.52 to 179.15, a 10.9% depreciation of the rupee that unfolded unevenly. The largest single-bar move of 2.8% delivered sudden shock moments amid otherwise gradual appreciation pressure, while the maximum drawdown of 2.4% offered only brief respites before selling resumed. Participants who treated each bar as an isolated decision faced a different challenge than those who maintained a process-driven view of the multi-week trend, highlighting how the same price data can generate wildly different assessments depending on time horizon and framework.
For decision training this replay excels at illustrating the psychological cost of being right directionally but wrong on timing. A 10.9% move over three months offers substantial rewards in theory, yet the volatility pattern—punctuated by 2.8% single-day spikes—tests position sizing and emotional regulation equally. The four critical decision points scattered across the period force participants to commit under uncertainty rather than wait for perfect clarity that never arrives in live markets.
