EMA20确认过滤效果显著：信号从31笔砍到10笔，胜率从19%→50%，复利1.59x → 周线信号出现后，等日线收盘在20EMA之上再入场，避免在持续下跌中接飞刀 2. RSI>30过滤（日线脱离超卖）类似：从31→16笔，比EMA20宽松一些 3. 尾随止盈（方案F）效果一般：平均-3.17% 原因：BTC脉冲式波动，尾随止损容易被正常回撤扫掉 4. 最佳折中：C方案（EMA20过滤 + 原SL=3% TP=6% ×10x） 10笔交易，50%胜率，1.59x复利，最大回撤-77% 虽然回撤不小，但相比原版的归零已经是质变 5. 本质问题是样本太少：7年半才10-16笔符合条件的交易 再怎么优化也不可能靠这个策略稳定盈利 """)
