Max drawdown

[REICHIYAN]

Dear Mr. @stefan-jansen

This is my first time contacting you.
I have purchased your book. It is very complete and informative.

Now, let me confirm the definition of maximum drawdown in pyfolio.

In this example, the maximum drawdown is negative, but I understand that it is calculated by [Maximum Drawdown [%]=(Traugh Value - Peak Value)/Peak Value*100]. Is this correct?

Some libraries define it as [Maximum Drawdown [%]=(Peak Value - Traugh Value)/Peak Value*100], so I would like to confirm this.

Best regards,
