Real-time visualization of cryptocurrency exchange rate movements

Kriptovalute v zadnjih letih postajajo vedno bolj popularne, zaradi česar se je trg kriptovalut občutno povečal in s seboj prinesel večje število novih investitorjev. Anonimnost, deregulirana narava in volatilnost trga omogočajo investitorjem hitrejši vstop in večje zaslužke v primerjavi s trgovanjem z delnicami. Povečana popularnost je povečala zahtevo po kvalitetnih orodjih za spremljanje takšnega trga. Namen diplomske naloge je razvoj realno-časovnega sistema za spremljanje in vizualizacijo gibanja tečajev kriptovalut, ki pridobiva podatke s pomočjo spletnega pajka in jih shrani v podatkovno bazo, nad katero se kasneje izvajajo vizualizacije in analize podatkov. Spletni pajek je izdelan kot namizna konzolna aplikacija v okolju .NET, ki lušči podatke iz podatkovnih virov in jih razčleni v primerno obliko. Za podatkovno hrambo in iskanje je uporabljeno orodje Elasticsearch. Prikaz, analiza in realno-časovne vizualizacije nad temi podatki pa se izvajajo s pomočjo orodja Kibana.Cryptocurrencies have become increasingly popular in recent years, and therefore the cryptocurrency market has increased significantly and brought in new investors. Anonymity, deregulated nature and volatility of the market enable investors quicker entry and higher earnings in comparison with stock trading. Increased popularity has increased the demand for quality tools, which monitor these markets. The purpose of this thesis is the development of a real-time system for monitoring and visualizing the movement of cryptocurrency exchange rates, which acquires data using a web crawler and stores it in a database. The stored data can then have visualizations and analysis performed on. A web crawler is designed as a desktop console application in a .NET environment that acquires data from data sources and parses it into a suitable format. Elasticsearch is used for data storage and search. The display, analysis and real-time visualization of data are performed by Kibana
