Calmar Ratio

The Calmar Ratio was authored by Terry W. Young in 1991. The higher the Calmar Ratio the better the instrument’s performance. The Calmar Ratio is the annual return divided by the maximum peak to trough negative return. The user must select linear bars but may change the input (close) and period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.
