For each symbol in your universe, we pull daily bars over the date range. On each bar we run the auto-tagger against synthetic features (RSI, MACD, position vs MAs, day pattern). Whenever a high-conviction setup fires, we open a virtual trade with the brain's recommended stop/target (ATR-based). Walk forward bar-by-bar to see if it hit T2 (3R), T1 (1.5R), or stop (-1R). Aggregate R, hit rate, win-rate by setup. This is the honest scoreboard for whether the brain's signals would have made money.
