{"title":"Price Channels of the Multitrading System","authors":"Felix Osvaldovich Kasparinsky","doi":"10.20948/abrau-2023-8","DOIUrl":"https://doi.org/10.20948/abrau-2023-8","url":null,"abstract":"The article is devoted to the phenomenon of the formation of price channels that limit fluctuations in quotations of financial instruments in the Forex Internet market. Price channels are used to predict the properties of groups of oscillations with a similar limit of deviation from the level of dynamic equilibrium between supply and demand. The stages of formation of a single oscillation (unidirectional price change) are considered in the context of Charles Dow's theory as a cooperative result of the actions of Internet traders interacting through Internet trading terminals. The specifics of constructing standard deviation and regression channels, equidistant price channels and Fibonacci channels, as well as Andrews Pitchfork are analyzed. A method has been developed for determining the location of Andrews Pitchfork pivot points using the signals of complex indicators of the multitrading system in the Metatrader 5 terminal. Correspondence of price fluctuations on two segments between three pivot points of Andrews Pitchfork to the first and second Elliott Waves has been established. Signals for verifying the relevance and loss of priority of Andrews Pitchfork are determined. The principles for determining and using a Trading group of three Analytical windows with different time scales are formulated: Andrews Pitchfork is formed in the Operational window with the smallest time scale, Tactical window indicators with a 4-fold time scale allow to unmask the boundaries of oppositely directed oscillations of the trend group, indicators of the Strategic window with a 16-fold time scale reveals the boundaries of the trend group of oscillations. The signs of a preliminary determination of the specifics of the Andrews Pitchfork structure are listed. A regulation has been created for the simultaneous use of Andrews Pitchforks formed on price charts with different time scales. Techniques for using the principles of interaction of Andrews Pitchforks of different scales to predict trends in the prices of financial instruments of various types are given. The ways of using Andrews Pitchfork to determine the optimal trading strategy in accordance with the specifics of financial instruments are discussed. Examples of tactical use of channels are given with evidence of their predictive power for medium and long-term trading strategies. Prospects for further research on the phenomenology of price channels are outlined.","PeriodicalId":475236,"journal":{"name":"Naučnyj servis v seti internet","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135052648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spatiotemporal variability of the total heat flux, which is the sum of latent and sensible heat fluxes, was modeled by a stochastic diffusion process. The coefficients of the stochastic differential equation representing the stochastic process were statistically determined from the original dataset. Previously, the existence and uniqueness of a solution in the strong sense of a stochastic differential equation generated by the constructed diffusion process were proved under the conditions of Kolmogorov. In this paper, we analyze the spatial and long-term variability of the heat flux field. For a given series of 40 years in length from 1979 to 2018, spatial maps and time curves were constructed.

Today Linux is one of the most popular operating systems in the world. The quality of the code of this OS (and in particular its kernel) directly affects the reliability and security of the entire range of products based on it. The international community of Linux developers is making great efforts to improve its reliability, using all kinds of testing methods and error detections. However, the number of new errors detected annually and the number of old errors that have not been corrected shows that these efforts are clearly insufficient. The methods of architectural analysis and fuzzing testing of the OpenvSwitch module were applied in the work. The syzkaller tool was used for fuzzing testing. One error, accepted into the main branch of the kernel, was found. The work is part of the project of the Linux Verification Center (ISP RAS).","PeriodicalId":475236,"journal":{"name":"Naučnyj servis v seti internet","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135053144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HTML has a number of advantages for online publications due to the availability of means for better material structuring, adding multimedia content, and implementing various kinds of interactive and dynamic possibilities. In this regard, the task of obtaining an HTML version of a scientific article from the original format of the material sent by the author becomes very relevant. The history of publishing full texts of scientific articles in HTML format is about 30 years old, but a unified approach to the preparation of such publications and tools accessible to all have not been developed during this time. Workflows of obtaining HTML-versions of articles in different publishers may be different. The approach largely depends on the personnel and financial capabilities of the publishing house. The paper considers the most popular of these approaches and describes the software tools applicable depending on the chosen approach. The main attention is paid to the tools used for source texts in Word format.","PeriodicalId":475236,"journal":{"name":"Naučnyj servis v seti internet","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135052668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Matematika\" journal. The collection consists of approximately 1100 documents in LaTex format. The work involves constructing an ontology for the collection of mathematical articles, which will serve as the basis for the created knowledge graph. Various article objects are extracted from the collection, including universal decimal classification codes, authors, titles, used formulas, articles publication dates, authors affiliations and references to other works. Each object is recorded through a specific relationship in the knowledge graph. Thematic modeling is also performed on the collection using the latent Dirichlet allocation method, for which optimal hyperparameters are selected. The document themes are recorded in the knowledge graph through relationships. An interesting approach is used for extracting mathematical terms. In this work, mathematical entities are identified in the documents using the OntoMathPRO ontology. During the knowledge graph construction process, tools were developed that allow the creation of a knowledge graph on any collection that meets the patterns of the original collection. The resulting knowledge graph can serve as a foundation for various research purposes and the development of intelligent systems, that can be used by researchers, journals, as well as students.","PeriodicalId":475236,"journal":{"name":"Naučnyj servis v seti internet","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135053458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern materials modeled within the framework of the theory of elasticity require new formulations of classical problems of mathematical physics. To describe new problems, it is necessary to establish connections between new terms and concepts with the classical definitions of the mathematical encyclopedia and other primary sources. Establishing links allows you to form a dictionary and thesaurus of the applied subject area of new boundary value problems and place the results in the semantic environment of the digital library. Examples of this approach are demonstrated using the capabilities of the LibMeta semantic library, which contains a digitized version of the mathematical encyclopedia and encyclopedia of mathematical physics, classifiers, and applied mathematical thesauri and dictionaries.

Russia is somewhat behind the leading countries in this area. The Russian-language Wikipedia has been developing more or less on a par with its neighbors. However, recently, unfortunately, anti-Russian articles began to appear there, which is why a group of wiki editors had to distance themselves from Wikipedia and initiate the creation of a new encyclopedia independent of it - Runiversalis. The Great Russian Encyclopedia, which is moving belatedly to the Internet, shows the still modest results. The article suggests certain solutions designed to intensify the reorganization of online encyclopedias and provide an additional level of comfort for the reader. Emphasis is placed on the need for permanent operational updating of articles posted on the web and the role of the Russian Academy of Sciences in the creation of encyclopedias.","PeriodicalId":475236,"journal":{"name":"Naučnyj servis v seti internet","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135053457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the middle of the XX century, within the framework of research conducted by argumentation theorists, theoretical approaches to the representation of argumentation have been developed, which form the basis of the representation of argumentation by means of software. The graphical capabilities of modern hardware and software are used for visual representation of argumentation.
