Query: On the use of financial analysis tools for the study of Dst time series
  in the frame of complex systems   Technical analysis is considered the oldest, currently omnipresent, method
for financial markets analysis, which uses past prices aiming at the possible
short-term forecast of future prices. In the frame of complex systems, methods
used to quantitatively analyze specific dynamic phenomena are often used to
analyze phenomena from other disciplines on the grounds that are governed by
similar dynamics. An interesting task is the forecast of a magnetic storm. The
hourly Dst is used as a global index for the monitoring of Earth's
magnetosphere, which could be either in quiet (normal) or in magnetic storm
(pathological) state. This work is the first attempt to apply technical
analysis tools on Dst time series, aiming at the identification of indications
which could be used for the study of the temporal evolution of Earth's
magnetosphere state. We focus on the analysis of Dst time series around the
occurrence of magnetic storms, discussing the possible use of the resulting
information in the frame of multidisciplinary efforts towards extreme events
forecasting. We employ the following financial analysis tools: simple moving
average (SMA), Bollinger bands, and relative strength index (RSI). Using these
tools, we formulate a methodology based on all indications that could be
revealed in order to infer the onset, duration and recovery phase of a magnetic
storm, focusing on the temporal sequence they occur. The applicability of the
proposed methodology is examined on characteristic cases of magnetic storms
with encouraging results for space weather forecasting.
