Methodology. We apply multifractal detrended fluctuation analysis (MF-DFA) to measure the efficiency of exchange rates. Before doing so, we employ the STL method to decompose the time series (Cleveland et al., ).Since we use five-minute returns, the STL method helps handle any type of seasonality because it is robust to outliers and flexible enough to allow seasonal multifractal structure of high frequency foreign exchange rate fluctuations book Cited by: 2.

Wei and Huang study high-frequency (per 5 min) data of Shanghai Stock Exchange Composite index (SSEC) from January to July with multifractal method. They use box counting method to calculate the multifractal spectra of SSEC, and propose a new market risk measurement, R f, which contains the integrated information of the two Cited by: 7.

Multifractal analysis provides powerful tools to understand the complex nonlinear nature of time series in diverse fields. Inspired by its striking analogy with hydrodynamic turbulence,Cited by: Multifractal behaviors in foreign exchange markets.

By analysing a high-frequency dataset of KOSPI futures, we also find that large trades reveal phase-shifting behaviour more clearly and. Multifractal analysis usually was accomplished in stock markets, seldom in exchange markets, especially in emerging markets. Empirical analysis of the Multifractal structure of the RMB/USD exchange market is performed using MFDFA method, based on the daily price from J to Ap We find that RMB/USD exchange market shows multifractal characteristic, and.

It is well known that empirical data coming from financial markets, like stock market indices, commodities, interest rates, traded volumes and foreign exchange rates have a multifractal structure.

Multifractals were introduced in the field of economics to surpass the shortcomings of classical models like the fractional Brownian motion or GARCH processes. The structure function approach dominated in the first wave of multifractal analysis in econophysics.

Since the seminal work of Kantelhardt et al in [ ], the multifractal detrended fluctuation analysis (MF-DFA) soon became the dominant method not only for financial time series but also for other time series. Download Multifractal Volatility Book PDF.

Three mathematical tests fail to find any signs of chaotic behaviour. The suggestion is that earlier announcements of chaos in such series may have been due to researchers using series with too few data points. Preliminary evidence is found for a ‘multifractal’ structure of the very high frequency Forex (Foreign Exchange) fluctuations.

Among the documents on the impact of exchange rate fluctuations upon multi-national enterprises, Jorion () indicated that all firms were susceptible to exchange rate exposure; however, the number of firms affected by exchange rate fluctuations was not high.

study on high-frequency trading (HFT) in the foreign exchange (FX) market, with a view to identifying areas that may warrant further investigation by the central banking community.

This initiative followed from a number of previous discussions by the Committee about factors contributing to changes in the structure of the global FX market. methodology is described and applied to Foreign exchange (Forex) market time series. Fluctuations of high-frequency exchange rates of eight major world currencies over – period are used to study cross-correlations.

The study is motivated by funda-mental questions in complex systems’ response to. High-frequency trading (HFT) has increased its presence in the foreign exchange (FX) market in recent years. A discussion is emerging about its benefits and risks, though the assessment is often hampered by difficulties in identifying and quantifying HFT as distinct from other forms of automated trading.

multifractal spectrum estimation of time series, such as methods based on generalized Hurst exponent [8] or wavelet transform [9]. Here we will focus on two most common techniques used for estimation of multifractal scaling exponents, namely Detrended fluctuation analysis [10, 11] and the Rényi-entropy-based Diffusion entropy analysis [12–14].

Downloadable. We present a systematic study of various statistical characteristics of high-frequency returns from the foreign exchange market. This study is based on six exchange rates forming two triangles: EUR-GBP-USD and GBP-CHF-JPY.

It is shown that the exchange rate return fluctuations for all the pairs considered are well described by the nonextensive statistics in terms of q-Gaussians. The multifractal nature of empirical data has been shown in financial markets, such as stock market indices [2,3,10,15,16,20,21,24,25,26,28], foreign exchange markets [1,23,29], commodities [ A graphical translation of “Foreign Exchange Market Structure, Players and Evolution”, by Michael R.

Analysis of High Frequency Financial Data: Models, Methods and Software. Part I: Descriptive Analysis of High Frequency Financial Data with S-PLUS. Eric Zivot∗ July 4, 1Introduction High-frequency ﬁnancial data are observations on ﬁnancial variables taken daily or at a ﬁner time scale, and are often irregularly spaced over time.

A multifractal system is a generalization of a fractal system in which a single exponent (the fractal dimension) is not enough to describe its dynamics; instead, a continuous spectrum of exponents (the so-called singularity spectrum) is needed.

Multifractal systems are common in nature. They include the length of coastlines, fully developed turbulence, real-world scenes, heartbeat dynamics.

The papers analyzed below pertain to my research in the following way. Ajayi and Mougoue (). Exposure to exchange rate risk implies that the international investor generally cares about both the volatility of the exchange rate and the correlation structure of exchange rates and foreign equity returns.

For example, higher exchange rate volatility tends to induce a home equity bias. Here X(t, Δt) = X(t+Δt)- X(t). For a true multifractal process, h will exhibit a wide range of values, whereas for monofractal process, h will approach a single value, such that the degree of multifractality of a given series can be estimated via the range of the h values (cf.).The resultant multifractal spectrum, with Hölder exponents plotted as the abscissa, and the fractal dimensions as.

A depreciating exchange rate is usually thought to be • Bilateral cross rates are expressed in foreign currency per domestic currency (E) and indexed to • The more “important” a competitor, the higher the weight of its currency are widely available with little lags and high frequency.

HDM WORKINGPAPER CHOOLOFMANAGEMENT HighFrequencyDataandVolatility inForeignExcliangeRates by BinZhou MITSloanSchoolWorkingPaper RevisedJanuary14, MASSACHUSETTS INSTITUTEOFTECHNOLOGY 50MEMORIALDRIVE CAMBRIDGE,MASSACHUSETTS In this study, panel vector autoregression (PVAR) models are employed to examine the relationships between industrial production growth rate, consumer price inflation, short-term interest rates, stock returns and exchange rate volatility.

More specifically, I explored the consequences of the dynamics detected by the models on monetary policy implementation for 10 OECD countries. This article uses tick-by-tick foreign-exchange rates to explore this new type of data.

Unlike low-frequency data, high-frequency data have extremely high negative first-order autocorrelation in their return. In this article, I propose a model that can explain the negative autocorrelation and a volatility estimator for high-frequency data.

Schmitt shows the multifractal characteristics of foreign exchange earnings and estimates parameters expressing the small and medium strength fluctuation characteristics under the general multiface structure by means of multifractal analysis regarding the five daily foreign exchange rates [19].

The multifractal property is proved to exist in. High-frequency trading (HFT) is a type of algorithmic financial trading characterized by high speeds, high turnover rates, and high order-to-trade ratios that leverages high-frequency financial data and electronic trading tools.

While there is no single definition of HFT, among its key attributes are highly sophisticated algorithms, co-location, and very short-term investment horizons. The applications of our approach to heart rate variability signals and high-frequency foreign exchange rates reveal that the difference between the correlation properties of the original signal and its magnitude fluctuations is induced by the time organization structure of the correlation function between the magnitude fluctuations of positive.

The structure of the paper is as follows: In Section 2 we introduce the multifractal models. Section 3 reports the empiri-cal and simulation-based results. A summary and concluding remarks are given in Section 4.

2 Markov-switching multifractal models In the Markov-switching multifractal model, ﬁnancial asset returns are modelled as: rt = ¾t. Rangarajan). The unification of the exchange rate was instrumental in developing a market-determined exchange rate of the rupee and an important step in the progress towards current account convertibility, which was achieved in August A further impetus to the development of the foreign exchange market in India was provided with.When exchange rates change, the value of a foreign subsidiary's assets and liabilities denominated in a as a result of exchange rate change fluctuations, when viewed from the perspective of the parent firm books, The functional currency would generally be the parent's currency.operations.

To measure the impact of exchange rate movements on a firm that is engaged in foreign-currency denominated transactions, i.e., the implied value-at-risk (VaR) from exchange rate moves, we need to identify the type of risks that the firm is exposed to and the amount of risk encountered (Hakala and Wystup, ).
