Can a losing trade still be a successful trading decision?
Suppose a trade follows the tested setup, uses the correct position size, and respects the stop-loss, but still loses. Meanwhile, another trade breaks the rules and happens to make a profit.
If we judge only by P&L, the second trade may appear better even though its process was worse.
How should traders score execution quality separately from financial results? Would a decision-quality journal help identify whether performance problems come from the strategy, randomness, or inconsistent execution?
