Opis:
Technical analysis rely on assumption that analysis of past market performance provides possibility for proper stock price forecasting, in particular by identification of buy and sell signals. The article describe main moving average models: simple moving average, weighted moving average and exponential moving average and manner of theirs usage while constructing investment strategy on financial market. The article outlines possibilities and limitations of moving averages usage in investment practice. In addition empirical verification of moving averages is provided for selected polish shares forming index WIG20.

Opis:
In this work we considered data on official Nigeria exchange rates (Naira to British Pound sterling) from January 2003 to December 2019. Four competing models ARIMA (1, 1, 1), ARIMA (2, 1, 1), ARIMA (1, 1, 0) and ARIMA (1, 1, 2) were identified for the exchange rates series. Diagnostic analysis revealed that all the competing models adequately represent the exchange rate series. However, on the basis of out-of-sample model selection and evaluation ARIMA (1, 1, 1) was selected as the optimal model with minimum information criteria for the exchange rate series. A 24 months forecast indicates that the Naira will continue to depreciate. The policy implication of our study is that the Central Bank of Nigeria (CBN), should devalue the Naira in order to not only re-establish exchange rate stability but also encourage local manufacturing and encourage foreign capital inflows.

Opis:
If market repeatability is assumed, it is possible with some real probability to deduct short term market changes by making some calculations. The algorithm, based on logical and statistically reasonable scheme to make decisions about opening or closing position on a market, is called an automated strategy. Due to market volatility, all parameters are changing from time to time, so there is need to constantly optimize them. This article describes a team organization process when researching market strategies. Individual team members are merged into small groups, according to their responsibilities. The team members perform data processing tasks through a cascade organization, providing solutions to speed up work related to the use of remote computing resources. They also work out how to store results in a suitable way, according to the type of task, and facilitate the publication of a large amount of results.

Opis:
The aim of the analysis of the time series is, among others, to facilitate the formulation of prognosis. The basis for the inference of the future variables are their future realizations. There are various methods used in time series forecasting, such as for example naïve method, Holt-Winters models, ARIMA models and various simulation methods. One of the most popular and widely used simulation method in statistical research is the bootstrap method proposed by B. Efron. It is usually applied in measuring the estimates of the variance and testing the hypotheses in cases when the distribution of the test statistic is unknown. This method does not require for the selected samples to be from the standard normal distribution population. Due to the construction of the random samples in this method, there is usually no possibility to directly apply it in the analysis of the periodic time series. In the literature written on this subject, there are the proposals to introduce some modifications to the bootstrap method that would provide the possibility to conduct such analyses. One of such methods is the moving block bootstrap. In the present essay, we will present the proposal to apply this method to create the confidential intervals for the periodic time series forecasts. The results gathered by applying that method are compared with the results obtained via the classic construction of the confidential intervals for the forecasts and on the confidential intervals based on ARIMA models.

Opis:
A method of simulating random fields using a moving average is proposed in this paper. Random fields were simulated for different sizes of sub-field and different numbers of cycles of calculations of the moving average. For the fields obtained the covariance function was analyzed. In order to estimate the efficiency of the proposed simulation method of random field based on the method of diagonal covariance matrix was performed. It is shown that two of the simulation methods presented are able to generate a multidimensional random variable with required correlation function. However, the method of diagonal covariance matrix has some limitations caused by the size of the simulated random field, which result from the necessity of converting a relatively large matrix. Using the proposed simulation method it is possible to simulate, in a comparatively quick and simple manner, a random field with a large number of nodes on PC-s. The presented method can be useful in the stochastic analysis of transport phenomena in soil.
