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 SDRs. 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.
