The plain-English definition
Max drawdown is the biggest fall from a high point to a later low point before the strategy recovered.
It helps answer: how painful did this strategy get along the way?
Why drawdown matters
A strategy can have a strong ending return and still be unrealistic for a user if it suffered a huge drawdown.
Drawdown is where behavior and psychology enter the strategy conversation.
How to use it in Stax
Compare drawdown against return, trade frequency, and your own risk tolerance.
If the drawdown feels impossible to sit through on paper, it will likely feel worse with real money.
Key takeaways
- Max drawdown shows the worst historical drop.
- It reveals strategy pain that return alone hides.
- A lower drawdown can be more important than a higher return.
