核心发现：不同波动率环境，最优卖点完全不同
三大规律：
① 高波=波动卖点为王：高波个股"波动下穿EMA"比"终止卖zh27"高+6.0%，高波ETF"终止zh19"与"波动OR"并列第一
② 中低波=终止卖为王：中波个股"终止zh27"比"波动下穿"高+3.4%，低波个股"终止zh27"唯一正收益
③ 止盈/移动止盈在所有维度全面溃败：固定止盈20%/30%、移动止盈10%/15%在ETF上-88%~-89%，个股上也大幅跑输

高波ETF：①终止卖zh19以+9.3%领先，MDD仅13.2%，P10 -10.9%。⑦波动下穿+终止OR几乎持平(+9.1%)但MDD更低(12.7%)。P10差距巨大：前两名P10约-10%，后四名P10超-80%——说明止盈逻辑的选择对尾部风险影响极大。

高波个股：③波动下穿EMA以+52.7%遥遥领先，MDD 36.4%。⑥波动线回落5%紧随(+47.2%)。关键差异：波动类卖点在高波个股上比终止卖多+6~+19%，因为高波环境波动线更敏感，能更早捕捉到趋势反转。GS死叉(+23.1%)反应太慢，错过主升浪。

止盈类卖点全面溃败
| 卖点 | ETF全部 | ETF高波 | 个股全部 | 个股高波 | 个股中波 |
|---|
| ⑨止盈20% | -88.1% | -88.4% | +9.2% | +21.1% | -13.7% |
| ⑩止盈30% | -88.2% | -88.7% | +1.9% | +12.8% | -17.6% |

| ⑫移动止盈15% | -89.0% | -89.3% | +2.9% | +15.2% | -18.8% |
止盈为什么全面溃败？ETF的双确认买点本身在底部区域，固定止盈20%/30%在底部买入后几乎不可能触发（ETF波动太小），导致长期持仓直到期末巨亏。个股上止盈20%在高波环境勉强可用(+21.1%)，但远不如波动卖点(+52.7%)。结论：趋势跟踪策略禁用固定止盈，必须用信号卖点。
◆ 结论
- 卖点比买点重要：同一买点下，不同卖点的收益差距高达60个百分点(个股高波: +52.7% vs -8.3%)
- 高波用波动卖点：波动下穿EMA/波动线回落5%在高波环境最敏感，能捕捉趋势反转
- 中低波用终止卖：终止zh27在中低波环境更稳定，信号噪音小
- ETF高波特殊：终止zh19最优(+9.3%)，因为ETF即使高波也比个股温和
- 波动OR组合值得尝试：波动下穿+终止卖OR在多个维度排名前三，兼顾敏感性和稳定性
- 止盈/移动止盈禁用：趋势跟踪策略的止盈逻辑是信号驱动，不是价格驱动
- GS死叉全面落后：反应太慢，在所有维度都不是冠军
