Smoothing a time series is achieved when a computer uses some pre-programmed calculation methods to remove noise from large volumes of data.

This helps the traders to have an idea of what to expect in the cost of trading.
Although smoothing reveals the patterns in a set of data, it provides no explanation as to why it is so. It is left to the researcher to draw conclusions as to the reasons for the patterns.
