What happened — and what it teaches

Between March and June 2021, copper—one of the most economically sensitive base metals—became a focal point for traders navigating the post-pandemic recovery. This 62-day replay captures a period when industrial demand expectations clashed with supply disruptions and macroeconomic uncertainty. Participants face a compressed timeline with 11 decision points, including 4 critical junctures that demand clear risk assessment and disciplined execution.

The market closed the period at 4.19 versus an opening of 4.07—a modest 2.9% net gain that conceals substantial intraperiod turbulence. A maximum drawdown of 13.0% tested portfolio resilience, while a single session delivered a 6.5% spike that challenged every position sizing strategy. The gap between headline return and actual volatility reveals why historical replay demands more than directional conviction.

Four critical moments punctuate this window, each forcing choices between conviction and capital preservation. The AI coach review afterward dissects whether decisions reflected process or reaction—examining entry timing, position sizing relative to drawdown comfort, and emotional discipline when a 6.5% single-bar surge threatens to derail the plan. This scenario excels at exposing the psychological gap between anticipating volatility in theory and managing it under live conditions.
