The largest equity drawdown from a previous peak was $30. That's your

Plus, PLEASE make it in percentage terms, not dollar terms. Dollar terms
are meaningless. One wants to know the percentage of capital lost from an

By the way, Sweeney used the term Maximum Adverse Excursion in a different
context. He covers this concept extensively in his book, Campaign Trading.
