Relative strength is the mean percentage change of each currency against its seven peers between the first and last
daily close of the week. A reading of +0.50% means the currency gained, on average, half a percent against
the other majors. Realized volatility is the standard deviation of daily log returns of each pair over the week,
annualized by ×√252. Full formulas are on the methodology page; the data
pipeline is documented in the docs.
