Historical Exchange Rates
The exchange of currencies from past to present gives us the chance to predict the future. Because of this, many investors examine the graphs of the change in the past periods before performing a transaction. There are some strategies used to examine the values of historical exchange rates.
These strategies examine a graph in three basic categories: the upward trend line, the downward trend line, and the horizontal trend line. Trend lines are an average of the exchange process of the currency in question. Upward means rising money value. Downward means the value of falling money.
And horizontal means the fixed value of money.
