  The classical technical analysis methods of financial time series based on
the moving average and momentum is recalled. Illustrations use the IBM share
price and Latin American (Argentinian MerVal, Brazilian Bovespa and Mexican
IPC) market indices. We have also searched for scaling ranges and exponents in
exchange rates between Latin American currencies ($ARS$, $CLP$, $MXP$) and
other major currencies $DEM$, $GBP$, $JPY$, $USD$, and $SDR$s. We have sorted
out correlations and anticorrelations of such exchange rates with respect to
$DEM$, $GBP$, $JPY$ and $USD$. They indicate a very complex or speculative
behavior.
