The best relative strenth meter that works on daily, weekly and monthly periods is RPFM-relative power forex meter (by relative strength I mean current pip movement compared with the average movement of last xx days).
It is working in Excel in real time and is connected with mt4. The end result are 9 most powerful/weakest pairs (of all 27 pairs) on daily, weekly and monthly bases.
RFPM calculates relative strength/weakness of each currency - eur, usd, gbp, jpy, aud, nzd, cad, chf. You will get number in % for each currency. From that you can easily get relative strength for every currency pair…also in % (where 100% is average for last xx days).
It is almost fully automated, it just needs a little adjusting as follows:
-for daily results needs about 5 min/per day of very simple update
-for weekly results it needs about 5 min/per week of very simple update
-for monthly results it needs about 5 min/per month of very simple update
