social networks analysis, news, and information that
influence people’s desire to buy, for instance. In fact,
this assessment intends to identify and model other
external influences, which were not addressed in this
study, to which the currency is subject.
Combining a qualitative approach to external in-
fluences, such as example, Twitter sentiment analysis,
and a quantitative approach based on the series’ own
values may be the most appropriate way to conduct
the research. Furthermore, these valuations can be a
promising study for currency forecasting.
