我的修改版：
\nworkflow_by_code.ipynb|attachment (23.4 KB)

用 gbdt(Gradient boosting Descision Trees) 在 2008-01-01~2022-12-31 的沪深 300（CSI300）数据上训练（用 2023-01-01~2024-12-31 时段的数据验证），TopkDropoutStrategy 在 2025-01-01~2026-01-01 的数据上测试，￥1M 本金一年考虑佣金等损耗的收益率为 36.3%。

想想我自己炒股是多么可笑：跟着感觉走，看 K 线图买，看行业新闻买

Why others should give you the money?

以下是 ipynb 跑的结果，有兴趣的同学可以自己改参数泡泡看：训练/测试时间段、本金、不同的预测模型。这是没有用到 RL、DL 的，只是 ML 中的 GBDT 方法。

以下是您提供的 JPMorgan LOXM AI 交易程序案例研究的中文翻译。

AI 案例研究：JPMorgan LOXM 实时自动执行股票交易程序

行业
\n金融服务
\n投资银行与投资服务

项目概述
\n摩根大通（JPMorgan）自 2017 年第一季度起在欧洲开始测试其 AI 程序 LOXM，该程序用于实时自动化股票交易执行，能够优化交易速度和价格，同时处理海量订单且不会引发市场波动。

试验取得成功后，银行计划于当年第四季度将其推广至亚洲和美国业务。

LOXM 直接应用于交易执行环节。摩根大通宣称，这是首家主要银行将 AI 技术应用于实时交易执行（而非仅用于事后分配等环节，其他同行大多停留在后端应用）。

Daniel Ciment（摩根大通全球股票电子交易主管）表示：虽然 LOXM 初期专注于交易自动化，但未来可能进一步训练系统，让其深入了解每位终端客户的个体行为与反应，从而在执行交易时考虑客户偏好。这种机器定制化方式，能更高效、大规模地实现个性化服务。

报告结果
\n据摩根大通称，在试验中，LOXM 实现了显著的成本节约，表现远超现有的手动交易和传统自动化交易方法。

核心技术
\nLOXM 通过深度学习（特别是强化学习）在数十亿笔历史交易数据（包括真实和模拟交易）上进行训练，使其能够在全球股票市场中：

以最快速度
以最优价格
执行大宗股票交易
同时将市场冲击（market impact）降至最低，避免引发价格剧烈波动

应用功能

运营优化
交易执行

背景与行业意义
\n金融机构越来越积极部署 AI 技术，以降低运营成本，因为 AI 在处理海量数据和从经验中学习方面表现日益出色。随着更多机构削减成本，同行之间的竞争压力也在不断加剧。

作为全球营收最大的投资银行，摩根大通如此大力投入 AI 技术，将进一步加剧对手的紧迫感，推动整个行业加速向 AI 驱动的交易执行转型。

补充说明（基于公开信息更新）
\nLOXM 项目最早于 2017 年公开披露，使用深度强化学习（Deep Reinforcement Learning）优化订单拆分与执行策略。后续报道显示，该系统已成为摩根大通交易基础设施的重要组成部分，并在 2020 年代持续演进，用于降低交易成本、提升执行效率，并在机构交易中贡献显著价值（部分报道提到年度节约可达数亿美元级别，并持续优化至覆盖更多资产类别）。

这份案例是金融行业早期成功将强化学习应用于实时交易执行的经典范例，展示了 AI 如何在高频、复杂的市场环境中实现超越传统方法的表现，同时兼顾合规与市场稳定性。
