PyTrendline v3 breakout metric re-audit

Generated: 2026-03-13 19:19 UTC

这页只做一件事:复核上一版 breakout side audit 里最容易误读的指标,避免把“breakout 本来就该穿线”误当成“所有 breakout 都几何失真”。

结论先说:上一版最醒目的 100% close-based 指标,主要是在重复 breakout 定义本身,不足以证明“全部 breakout 行都坏了”。真正值得修的 blocker 是:严格几何异常仍然存在,但规模远小于 100%;另外 purged 样本里还保留了 1 条完全镜像、且 crossed_lines_share = 100.0% 的 paired breakout row。

Plain-language summary

这轮没有声称的事:还没有重跑修复后的最小样本,所以这页不是 fix closure。它完成的是 把 fix 目标重新描述准确:下一步应该瞄准“严格几何异常 + exact mirrored pairs”,而不是假设所有 breakout 记录都该被判死刑。

Corrected metric table

legacy_close_based_share = 上一版最容易误读的指标;strict_wrong_side_share = 更接近“线在事件 bar 前就已经跑到错误一侧”的强检查。

Pair-level reminder

虽然“全部 breakout 都坏了”这个说法不成立,但 paired mirrored rows 依然值得优先修,因为那是明确无争议的坏样本。
