The problem of methods for analyzing nonlinear oscillations is now a general scientific, fundamental one, especially in the field of information systems with a large amount of data. In this paper, the analysis takes place on a test example of exchange data to identify hidden connections, general patterns, trends and fluctuations. According to the results of the analysis, it is expected to identify the desired ergodic dependence, as well as distinctive features of data behavior in the identified areas of almost-periods and almost-proportions.
