Abstract
High-frequency trading (HFT) has become a household term and a favourite topic for the financial media since the flash crash of May 2010. In this article, it is argued that the criticism directed at HFT is misplaced and based on a misconception of what HFT is all about. Specifically it is argued that HFT did not cause or exacerbate the flash crash, that it is not as profitable as it is typically portrayed to be, and that it is confused with other operations. Counterarguments are presented against the arguments put forward by the opponents of HFT. Although the case for a special regulation of HFT is weak, abusive practices such as ‘front running’ should be banned, whether they are associated with high-frequency or low-frequency traders. More importantly, however, there are more serious matters that regulators should be preoccupied with than traders who buy and sell frequently.

Alternatively, a short position is taken on an asset and subsequently it is unwound by buying the asset at a lower price. Market making works on a similar principle as the market maker buys at the lower bid price and sells at the higher ask price, thus realising as profit the bid-ask spread.
At that time the term HFT had not been coined yet. It was known as ‘computer-based trading’ or something close to that.

Another example of statistical arbitrage is ‘pairs trading’, a strategy that aims at exploiting temporary deviations from a long-run relation between two cointegrated financial prices.
This is actually the prime characteristic of HFT and should come first.
‘Low latency’ refers to the rapid execution of transactions. It follows that HFT is a low-latency operation.
