What happened — and what it teaches
China's hot-rolled coil market entered a volatile period from mid-2020. The scenario covers 66 trading days starting July 23, 2020, through October 30, 2020. This was a period when ferrous markets faced significant uncertainty amid post-pandemic recovery dynamics. The 2020s decade context means traders had to navigate unprecedented conditions. Twelve decision points await, four of them critical, demanding careful analysis at each turn.
The closing price moved from 3840 to 3864, a modest 0.6% gain over the full period. However, this headline figure masks substantial turbulence within. The maximum drawdown reached 9.5%, and the largest single-bar move hit 2.3%, indicating frequent sharp reversals that tested traders' conviction and discipline. Those who focused solely on the end result would have missed the real story of navigating intermediate volatility.
This replay teaches that survival during drawdowns requires process over prediction. Participants learn to manage risk when facing a 9.5% peak-to-trough decline without knowing whether the next bar will bring relief or further pain. The scenario develops emotional discipline by forcing decisions without hindsight bias, building habits that transfer to live markets. Completing the 66 daily bars and resolving all 12 scenario points, learners gain practical experience in maintaining composure through volatility cycles that characterize commodity trading.
