Drawdown 算法
A self-paced text walkthrough, without video or audio. See the article below for worked examples and materials.
Course Notes
In "Quant Risk Framework" → "回撤约束", this lesson "Drawdown 算法" builds knowledge you can apply immediately.
回撤算法逐点维护历史权益峰值，比较比例而不是绝对差。初始峰值、非正权益、现金流和缺估值都需要定义。 验证权益序列→更新running max→算1−equity/peak→取最大→记录峰谷时点→现金流另调。 本课作业：权益100/120/108/126/113.4，求两次谷值回撤及最大值。
These points align with the video walkthrough—take notes as you watch.
After studying, complete the companion practice lesson to move from understanding to doing.
