Publisher's Synopsis
Excerpt from High Frequency Data and Volatility, in Foreign Exchange Rates
Since the consecutive prices are nonstationary, it is appropriate to study changes in prices. Like many other researchers, I prefer to study the compound return (which is defined as the difference in the logarithmic value of the bid prices). Table 2 shows the summary statistics of the tick-by-tick returns. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
