چکیده
Properties of low-variability periods in the time series are analysed. The theoretical approach is used to show the relationship between the multi-scaling of low-variability periods and multi-affinity of the time series. It is shown that this technically simple method is capable of reveling more details about time-series than the traditional multi-affine analysis. We have applied this scaling analysis to financial time series: a number of daily currency and stock index time series. The results show a good scaling behaviour for different model parameters. The analysis of high-frequency USD-EUR exchange rate data confirmed the theoretical expectations.

متن کاملProbability of Large Movements in Financial Markets
Based on empirical financial time-series, we show that the ”silence-breaking” probability follows a super-universal power law: the probability of observing a large movement is inversely proportional to the length of the ongoing low-variability period. Such a scaling law has been previously predicted theoretically [1], assuming that the length-distribution of the low-variability periods follows ...

A search for faint slowly variable objects was undertaken in the hope of finding QSO candidates behind the Small and Large Magellanic Clouds (SMC and LMC). This search used the optical variability properties of point sources from the Magellanic cloud OGLE-II photometric data. Objects bluer than V −I = 0.9 and within 17 < I < 20.5 were studied. Robust variograms/structure functions have been com...
متن کاملThe Impact of Financial Market Fluctuations on Financial Instability in the Iranian Economy: The Wavelet based Markov Switching Model
In this study, the effect of fluctuations of asset markets (exchange rate, oil price and stock market index) on financial instability index over a period of 1388-1397 monthly is investigated by using the Markov Switching model. The wavelet transform model is used to extract exchange rate fluctuations, oil prices and stock market index. The results show that the effect of exchange rate fluctuati...
متن کاملOverview and Comparison of Short-term Interval Models for Financial Time Series Forecasting
In recent years, various time series models have been proposed for financial markets forecasting. In each case, the accuracy of time series forecasting models are fundamental to make decision and hence the research for improving the effectiveness of forecasting models have been curried on. Many researchers have compared different time series models together in order to determine more efficien...
