The Treynor ratio is a measure of the excess return with respect to the risk-free rate per unit of systematic risk. The systematic risk is the beta of the asset or portfolio with respect to the asset.
The Treynor ratio is defined as: $$ \begin{eqnarray*} T = \frac{R_i - R_f}{\beta_i} \end{eqnarray*} $$ where $R_i$ is the asset return, $R_f$ is the risk-free return and $\beta_i$ is the portfolio's beta.

    DoubleTimeSeries<?>[] series = TimeSeriesIntersector.intersect(riskFreeReturnTS, assetReturnTS);
    riskFreeReturnTS = series[0];
    assetReturnTS = series[1];
    final TreynorRatioCalculator calculator = getCalculator(constraints.getValues(ValuePropertyNames.EXCESS_RETURN_CALCULATOR));
