How to read the badges. A backtest can only measure the blind, mechanical version of a system — take every signal, no judgment. But the books all say the real edge is in the judgment: bias, key level, session, narrative. So a system that "lost mechanically" isn't dead — it means the edge, if it exists, lives in the part only you can add. Learn the system, then be your own backtest: demo it, count your results, decide with data. That's the whole point.
