Methodology: The brain captures predictions in bpleone_pred_journal_v1. Once each prediction has aged past its horizon (1 day for short), the actual price move is compared to the brain's call. Win = direction matched and move > 0.3%. This page replays every resolved trade with the sizing rule risk = bankroll × riskPct × max(0.2, |conviction − 0.5| × 2), capping upside at +5R and downside at −1R (stop assumption). The shown P&L is what you would have made if you had taken every signal at this size and held to the brain's resolution horizon.
