What happened — and what it teaches

The summer of 2018 brought a sharp reversal to coffee futures markets. After a period of relative stability, commodity traders faced a critical test as soft markets began to crack. This replay covers 68 trading days from June 20 to September 25, 2018, placing participants in the shoes of traders navigating an emerging downtrend. The stakes were clear: how would you manage positions when the broader trend turned against you?

The numbers tell a stark story. Arabica coffee futures fell 14.6% from 113.65 to 97.1 over this period, with a maximum drawdown of 19.9%. The volatility was punctuated by a largest single-day move of 5.1%, testing the composure of even experienced traders. Participants faced 12 decision points, including 4 critical moments that could significantly alter portfolio outcomes. This was not a slow bleed but a volatile descent that demanded constant reassessment.

This scenario hones the art of managing losing positions under pressure. Traders must grapple with the psychological pull of averaging down versus cutting losses, the challenge of sizing positions to survive drawdowns, and the discipline needed to act decisively at critical junctures. The 2018 coffee slide serves as a stark reminder that even soft commodities can deliver sharp, unpredictable moves that separate disciplined risk managers from reactive gamblers. Training through such historical episodes builds the emotional resilience and systematic thinking essential for surviving real market turbulence.
