HFT-järjestelmien tehokkuuden parantaminen

2016

Teknologian kehittyminen on avannut uusia liiketoimintamahdollisuuksia myös finanssialalle. Automatisoitu arvopaperikaupankäynti on vakiinnuttanut asemansa arvopaperimarkkinoilla ja yritykset etsivät yhä parempia tapoja saavuttaa kaupankäyntietuja muihin kaupankävijöihin nähden. Automatisoidussa arvopaperikaupankäynnissä nopeuden on nähty olevan kaupankäynnissä eduksi, jolloin markkinamuutoksiin voidaan reagoida ennen muita kaupankävijöitä. Alan yritykset ovatkin ryhtyneet niin sanottuun nopeuskilpailuun ja pyrkivät tehostamaan kaupankäyntijärjestelmiään. Nopeasta automatisoidusta arvopaperikaupankäynnistä voidaan käyttää lyhennettä HFT (High Frequency Trading). Tämän kirjallisuuskatsauksee…

Wpływ handlu zagranicznego Unii Europejskiej na rzeczywistą emisję CO2

2016

Emisja CO2 jest problemem globalnym. Oznacza to, że walka tylko części krajów w tym obszarze niewiele zmienia. Celem niniejszego artykułu jest próba ukazania rzeczywistego poziomu emisji CO2 w UE, jak również wpływ wymiany handlowej Unii na emisję CO2 u jej głównych partnerów handlowych. Badanie zostało przeprowadzone na grupie 20 głównych partnerów handlowych UE i samej Unii. Rzeczywisty poziom emisji CO2 uzyskano przez zastosowanie wskaźnika emisji rzeczywistej. Jego wielkość uwzględnia transfer CO2 w produktach i usługach eksportowych, a także importowanych przez poszczególne kraje. W wyniku jego zastosowania okazało się, że rzeczywisty poziom emisji CO2 w badanych krajach jest znacznie …

Customer satisfaction within a large scale retail trading group: research design and control

2010

Even in contexts where Customer Management techniques are not very advanced, the need for relations with customers is as strong as to suggest expensive ad hoc researches able to simultaneously measure the satisfaction levels, to detect the eventual inadequacy of selling actions, to investigate the relations of customers with competitors. This is why the Grande Migliore Group in Palermo commissioned a research from the University of Palermo. The research was made in year 2008 at 10 Grande Migliore shops in Palermo and in other Western Sicily towns. The multipurpose nature of the research and the features of the customers population suggested the adoption of an ad hoc research design, the fea…

E-NAUTILUS: A decision support system for complex multiobjective optimization problems based on the NAUTILUS method

2015

Interactive multiobjective optimization methods cannot necessarily be easily used when (industrial) multiobjective optimization problems are involved. There are at least two important factors to be considered with any interactive method: computationally expensive functions and aspects of human behavior. In this paper, we propose a method based on the existing NAUTILUS method and call it the Enhanced NAUTILUS (E-NAUTILUS) method. This method borrows the motivation of NAUTILUS along with the human aspects related to avoiding trading-off and anchoring bias and extends its applicability for computationally expensive multiobjective optimization problems. In the E-NAUTILUS method, a set of Pareto…

Il problema della definizione della "illiceità"della mediazione nel nuovo reato di traffico di influenze illecite

2022

Le modifiche apportate al delitto di traffico d’influenze illecite ad opera della legge n. 3/2019 hanno accentuato il deficit di determinatezza che già caratterizzava la fattispecie sin dalla sua introduzione, delineando un modello di incriminazione incapace di selezionare le condotte di intermediazione penalmente rilevanti distinguendole dalla attività di lobbying consentita. Il lavoro analizza la specifica questione dell’interpretazione del predicato di “illiceità” della mediazione esaminando le diverse tesi proposte in dottrina e in giurisprudenza. Conclusivamente, l’Autore ritiene che l’interpretazione restrittiva dell’art. 346-bis c.p., che inquadra la fattispecie come delitto “avampos…

A New Perspective on the Relationship between Trading Variables and Volatility in Futures Markets

2017

In this paper, we study the relationship between trading-related variables and volatility in futures markets, from a new unifying perspective, which is based on the separation of open and closed positions. Volatility in stock index futures markets (Standard & Poor’s 500, DAX 30 and Nikkei 225) is related to the flow of contracts entered into the markets and the flow of contracts that are closed out. In general, the daily changes in the number of open and closed positions are both positively correlated with volatility. Additionally, there is a stronger positive relationship between the number of open (respectively, closed) positions and contemporaneous volatility on those days when t…

FPGA-piirien hyödyntäminen ultranopeassa automatisoidussa kaupankäynnissä

2012

Ultranopeassa automatisoidussa kaupankäynnissä (HFT) aika on rahaa ja jo millisekunnin etu kilpailijoihin nähden voi tuottaa suurenkin voiton. Optimoinnin HFT-järjestelmän joka osissa nopeuttavat järjestelmää. FPGA-piirien käyttö voi nopeuttaa HFT-järjestelmää huomattavasti. Erityisesti FPGA-piiri soveltuu markkinasyötteen käsittelyyn. FPGA-piireillä savutetaan 5-22 kertainen nopeus yleiskäyttöiseen suorittimeen nähden markkinasyötteen käsittelyssä In high-frequency trading (HFT) time is money. Even a one millisecond advance to other traders can bring huge wins to the HFT system. Optimazations in different parts of the HFT system can make system faster. Using FPGAs signifacantly decreases l…
