What happened — and what it teaches
The spring of 2021 found Chinese coking coal markets in the grip of a vigorous upswing, a period when supply constraints and robust steel demand converged to push commodity prices to notable heights. This 56-day replay window from mid-April through early July captures a moment when market participants faced consequential choices amid intensifying volatility. The scenario immerses traders in daily decision-making where each move carried weight, and where the difference between prudent risk management and reactive trading could define outcomes.
Across these 56 daily bars, coking coal prices climbed from 2386.5 to 2641, representing a 10.7% advance over the full span. Yet the trajectory was anything but smooth—a maximum drawdown of 20.3% tested positions and conviction, while a largest single-bar move of 7.4% reminded participants that volatility arrives without warning. The closing price masked an interior journey of sharp rallies and unsettling reversals, demanding continuous reassessment rather than passive holding.
This replay offers structured practice in navigating environments where both opportunity and danger coexist. Ten decision points, four deemed critical, compel traders to articulate their reasoning under pressure. The scenario trains the habit of distinguishing between temporary fluctuations and structural shifts, a skill essential for anyone managing positions through turbulent markets. By confronting authentic historical volatility in a simulated setting, participants can refine their process, strengthen their risk discipline, and build psychological resilience without risking actual capital.
