Nel seguente lavoro si propone un’analisi dei sistemi di trading ad alta frequenza (Hft); il fenomeno ha avuto origine e si e sviluppato sul mercato azionario statunitense, ma, nel corso degli ultimi anni si sta progressivamente espandendo alla maggioranza delle asset class sui principali mercati finanziari globali. L’analisi si compone di un approfondimento delle attuali strutture regolamentari e tecnologiche dei mercati, di una definizione delle inefficienze e dei vantaggi informativi che gli Hfts cercano di sfruttare e delle diverse strategie utilizzate. Il lavoro termina con una valutazione degli impatti positivi e negativi per la qualita complessiva dei mercati finanziari derivanti dalla presenza di tale, nuova tipologia di player.This paper examines high-frequency trading systems, which were first developed in the US equity markets but have spread steadily to most asset classes on the main world financial markets. It analyzes the current regulatory and technological structures of the markets and describes the inefficiencies and informational advantages that high-frequency trading systems seek to exploit and the strategies they use. The paper concludes with an assessment of the positive and negative impacts of the presence of this new type of player on the overall quality of the financial markets.
