Nominal EERs are calculated as geometric weighted averages of bilateral exchange rates. Real EERs are the same weighted averages of bilateral exchange rates adjusted by relative consumer prices. The weighting pattern is time-varying, and the most recent weights are based on trade in 2008-10 (see broad and narrow weights). The EER indices are available as monthly averages.An increase in the index indicates an appreciation. ——BIS关于eer的说明 所以应该是间接标价法
