Currency Strength Meter
Which of the four majors looks relatively firm over the last few days?
This meter builds a relative USD / EUR / GBP / JPY score from major-pair daily log returns (server-cached closes). It ranks those four among themselves.
All you need is a lookback window (1, 5, or 20 trading days). Bars update from the same history used for correlation.
