We perform a comparative study of applicability of the Multifractal Detrended
Fluctuation Analysis (MFDFA) and the Wavelet Transform Modulus Maxima
(WTMM) method in properly detecting of mono- and multifractal character of
data. After summarizing the theory behind both methods, we apply both methods
on USD/TRY currency. The results show that our data has multifractal nature but
not at high level and multifractality is poorer if WTMM method is used. We also
investigated whether other Eastern European country currencies, such as Russian
Rubble and Hungarian Forint have multifractal characters by using MFDFA
method. Therefore, forecasters have often encountered in trying to predict these
exchange rates with models that do not incorporate any notion of inhomogeneity
will have little predictive power.
