A method like the detrended uctuation analysis is recalled emphasizing its value in sorting out correlation ranges, thereby leading to predictability at short horizon.
The m; k -Zipf method is presented for sorting out short-range correlations in the sign and amplitude of the uctuations. c Elsevier Science B. All rights reserved. Hypothetical or simulated performance results have certain limitations. Unlike any actual performance record, simulated results do not represent actual trading.
Also, since the trades have not actually been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity.

No attempt is made to provide an extensive review of the literature. In the spirit of the lectures as requested by the organizers, trans- parence and pedagogy should hopefully be the main pillars of what follows.
Moreover, not all practical techniques will be covered. As in the oral lecture, the multifractal analysis tech- nique is mentioned only when and if useful for the approaches and topics to which it can be connected. The wavelet method [1] and the quasi-equilibrium thermodynamics approach [2] are not touched upon here, statistical physics in forex. Many interesting topics, statistical physics in forex, basic and advanced ones can be found in the recent book by Mantegna and Stanley [3].
As a preliminary statement let it be recalled that even though the error bar sizes are not often mentioned, the author has much practice in critical exponent analysis and their extraction from experimental data. He has shown persistency [4 —9] in getting the best technique available for sorting out numerical values.
in Refs. Moreover even though not all analyzed data technique and results have been checked statistical physics in forex respect to standard physical signals like fractional Brownian motion, white noise, etc.
Nevertheless, it is necessary to warn against mistreatment of data, and as pointed out elsewhere [10], one can sometimes obtain quite varied mean values, large error bars or even unreliable parameters. More sophisticated statistical techniques than I have used or I am familiar with can surely be used with modern computers.
However, there is no strict need to request extreme precision from the technique due to the practical aspects which are intended here and the obvious safety factors which have to be used in such a risky subject indeed, i. No data point is supposed to be missing. be an integer. This interval is called the scaling range. Outside the scaling range the error 1 A brief discussion of statistical physics in forex Hurst exponent and other usual exponents found in the text is given in Appendix. Such crossovers from fractional to ordinary Brownian motion are well observed.
The case of overlapping boxes has been recently examined and the result shown in Fig. To consider overlapping statistical physics in forex might be useful when not many data points are available. However, it was feared that extra insidious correlations would thereby be inserted. For example, in Fig. This should allow one to probe statistical physics in forex existence or not of locally correlated or decorrelated sequences, statistical physics in forex.
This has also been done for liquid water content and brightness temperature of stratus clouds [17]. since there is no water or cloud surface temperature uctuation anymore. for a Brownian motion long series as in Fig.
The variation depends on the box size. In Figs. A positive uctuation is likely to be followed by another positive one. However, in some drift is observed toward a value ca. It is clear that some economic or FEXC policy change occurred inand a drastic one at the end of in order to render the system more Brownian-like. Therefore, statistical physics in forex, it can be claimed that this procedure interestingly leads to a local mea- surement of the degree of long-range correlations, thus of local persistence or not.
time corresponded to changes in the Bundesbank interest rate increase or decrease. However mere mil- itary events or political ones or others, like the Gulf War or Spanish nurses strikes, were somewhat irrelevant. It is easily observed whether there is persistency or antipersistency in some exchange rate, — according to the local value of. Thus, statistical physics in forex, some guess whether the next uctuation should be positive or negative can be made.
Therefore statistical physics in forex buy or sell decision can be taken. Note: DEM ' DKK on January 01, Zipf analysis technique The above DFA technique considers the sign of the uctuations and their persis- tence, but it falls short of implementing some strategy taking into account the amplitude of the uctuations.
This technique, orig- inally introduced in the context of natural languages is performed by calculating the frequency of occurrence f of each word in a given text. The number of words for a given alphabet with a certain number of characters is given in Table 2.
A power law in f R is expected to be observed in correlated sequences [20,21]. There is no theory at this time predicting the exponent as a function of m; k.
It has been shown in previous work [20] that the technique is rather weak for a predictability purpose when only two characters and short words are considered [20].
After having decided on the number k of characters or Ising spin values of the alphabet, the signal can be transformed into a text statistical physics in forex Ising chainand thereafter analyzed with respect to the frequency of words of a given size m to be ranked accordingly.
In our work, words of equal lengths were always considered. The words can be ranked according to their frequency and a power law or not observed on a log—log plot.
The above procedure does not take into account the trend, statistical physics in forex. For a positive or negative trend over the statistical physics in forex box which is investigated, a bias can occur between words. For a two-character alphabet, e. Such a bias can be taken into account with respect to the equal probability occurrence, e. A new ranking can be made. A variant consists in comparing on a histogram [21] or on a normal—normal plot, the observed word occurrence probabilities vs.
or in presence of trend. Indeed for m and k large not all words do occur, statistical physics in forex. Even though, e. Moving-average analysis technique Stock market indices have often appeared to be cyclical. In recent years, some less trivially deterministic content has been looked for as hidden in some characteristic noise parameter, e. The fractal dimension D is related to Hu, — see the appendix.
We have discovered that a very usual technique used by chartists and analysts, known as the moving-average analysis MAA technique, contains an interesting way for determining Hu for a y t signal [23]. One can easily show that if y increases resp.
Thus, the moving average captures the trend of the signal over the considered time statistical physics in forex N. T1 and T2 intervals such that T2 ¿ T1. This leads to pessimism concerning the behavior of the signal which should later hit some minimum.
In fact, the fractal dimension D of the set of crossing points is trivially one. This suggests a lack of robustness, when forecast from gold and death cross distribution is made and this enables to work out the investing strategy.
This result certainly raises fundamental questions on the properties of fractional or not Brownian motion processes. Notice that the moving-average method can serve to measure the Hurst exponent in a very fast, elegant and continuous way. In this respect, connection to multifractal analysis 2 can be made [29,30]. This corresponds to obtaining a spectrum of moving averages indeed [24], statistical physics in forex. The Hurst exponent for various fractional Brownian motion signals as measured by the detrended uctuation statistical physics in forex DFAmoving average analysis MAA and multi-fractal analysis MFA methods.
