What happened — and what it teaches
The PSI 20, Portugal's benchmark equity index, entered a correction phase between June 25 and September 10, 2015. This 56-bar daily dataset, spanning the 2010s decade, offers a structured replay with 10 decision points, 4 of them critical, where participants can test their responses to a deteriorating market environment. The scenario challenges traders to navigate an extended pullback without succumbing to panic or false bravado, making it a valuable exercise in discipline under pressure.
The index descended from 5817.54 to 5057, delivering a -13.1% total loss over the period. A maximum drawdown of 15.4% tested the resolve of anyone holding positions, while a largest single-bar move of 5.8% served as a stark reminder that corrections can accelerate without warning. Participants who failed to respect these dynamics found their portfolios compounding losses as volatility worked against them.
This replay sharpens decision-making under stress. The 4 critical junctures force participants to choose between holding, reducing exposure, or adapting strategy when trends weaken. The scenario teaches that managing drawdowns matters more than capturing every rally, and that psychological resilience often separates survival from capitulation in correction environments.
