High-Frequency Trading HFT: What It Is & How It Works

HFT has been making waves and ruffling feathers (to use a mixed metaphor) in recent years. But regardless of your opinion about high-frequency trading, familiarizing yourself with these HFT terms should enable you to improve your understanding of this controversial topic. Interestingly, an exchange’s co-location clients receive the same amount of cable length regardless of where they are located within the exchange premises, so as to ensure that they have the same latency. The 2010 Flash Crash only lasted 36 minutes, yet managed to wipe out $1 trillion in market value. And spoofing is considered to be one of the contributing factors of this market crash.

  • HFT firms use different types of High Frequency Trading Strategies and the end objective as well as underlying philosophies of each vary.
  • The algorithms also dynamically control the schedule of sending orders to the market.
  • The method is employed by large investment banks, hedge funds, and institutional investors who try to take advantage of the market conditions before anyone else.
  • Many researchers have been studying the impacts of HFT on the markets and have come up with differing views.

The method is employed by large investment banks, hedge funds, and institutional investors to take advantage of the market conditions before anyone else. High-frequency trading operates as an automated trading method investible or investable driven by algorithms that identify lucrative trading prospects. Employed by banks, financial institutions, and institutional investors, HFT enables rapid execution of extensive trade batches within a short timeframe.

On the other hand, with a Low Order Arrival Latency, the order can reach the market at the most profitable moment. HFT players rely on microsecond/nanosecond latency and have to deal with enormous data. Long-range dependence (LRD), also called long memory or long-range persistence is a phenomenon that may arise in the analysis of spatial or time-series data. This relates to the rate of decay of statistical dependence of two points with increasing time interval or spatial distance between the points. It is a must to note that a phenomenon is usually considered to have long-range dependence if the dependence decays more slowly than an exponential decay, typically a power-like decay.

  • High-frequency trading strategies may use properties derived from market data feeds to identify orders that are posted at sub-optimal prices.
  • It became popular when exchanges started to offer incentives for companies to add liquidity to the market.
  • The firms engaged in HFT often face risks related to software anomaly, dynamic market conditions, as well as regulations, and compliance.
  • This remarkable speed empowers traders to carry out sizable trade orders with exceptional efficiency.
  • It involves providing rebates to market order traders and charging fees to limit order traders is also used in certain markets.
  • Advanced computerized trading platforms and market gateways are becoming standard tools of most types of traders, including high-frequency traders.

Currency traders wouldn’t be blind to the sudden surge in activity around the euro and would react, causing the market to move in response to a series of trades made purely based around millisecond arbitrage. This system allows traders to profit off of a sheer number of trades that would be impractical or impossible for a manual trader. Through automation, a high-frequency trader can conduct enough trades in enough volume to profit off even the smallest differences of price. Many researchers have been studying the impacts of HFT on the markets and have come up with differing views. One academic study published on Berkeley’s website found that high-frequency trading on large-cap stocks during times when they are generally rising reduces the cost of trading and makes quotes more informative.

The software algorithm that forms the nucleus of an exchange’s trading system and continuously matches buy and sell orders, a function previously performed by specialists on the trading floor. Since the matching engine matches buyers and sellers for all stocks, it is of vital importance for ensuring the smooth functioning of an exchange. The matching engine resides in the exchange’s computers and is the primary reason why HFT firms try to be in as close proximity to the exchange servers as they possibly can. Computers are definitely faster than humans, so these systems can make more transactions and increase the liquidity of the market. As mentioned above, these companies probably make less than a penny from each trade.

HFT facilitates large volumes of trades in a short amount of time while keeping track of market movements and identifying arbitrage opportunities. However, even the slightest fraction of a second lag presents an opportunity to high-frequency traders because of the ultra-fast nature of the automated trading system used in HFT. As we have already stated, high-frequency trading happens in a few one good trade millionths of a second — just about the time it takes for a computer to process an order and send it out. High-frequency trading (HFT) uses algorithms and extremely fast connections to make rapid trades, often in fractions of a second. It frequently involves the use of proprietary tools and computer programs that analyze markets, identify trends, and execute trades for very short-term gains.

For example, in the US, they have circuit breakers to suspend trading if the market is moving abnormally in one direction. Furthermore, regulators are always eager to punish market manipulators, as can be seen in the case of Trillium Capital that was sanctioned by the FINRA.

Taking advantage of such a type of deception is widely considered immoral and sometimes illegal.

What Is High-Frequency Trading (HFT)? How It Works and Example

The stock price movement takes place only inside the bid-ask spread, which gives rise to the bounce effect. This occurrence of bid-ask bounce gives rise to high volatility readings even if the price stays within the bid-ask window. HFT involves analyzing this data for formulating trading Strategies which are implemented with very low latencies. As such it becomes very essential for mathematical tools and models to incorporate the features of High-Frequency data such as irregular time series and some others that we will outline below to arrive at the right trading decisions. As the race to zero latency continues, high-frequency data, a key component in HFT, remains under the scanner of researchers and quants across markets. The precision of signals (buy/sell signals) is paramount since gains may quickly turn to losses if signals are not transferred rightly.

This proved itself to be a poor source of revenue and an inadequate mechanism to regulate the equity market. If the price movement differs, then the index arbitrageurs would immediately try to capture profits through arbitrage using their automated HFT Strategies. To do it effectively, trend following strategy the High Frequency Trading Arbitrage Strategies require rapid execution, so as to quickly maximise their gains from the mispricing, before other participants jump in. Order flow prediction Strategies try to predict the orders of large players in advance by various means.

High-frequency trading, or HFT, is a trading method that employs computers to conduct a large number of transactions in fractions of a second. Computers use complex algorithms to analyze the markets and execute transactions based on conditions in them. The main benefit of high-frequency trading is the speed and ease with which transactions can be executed. Banks and other traders are able to execute a large volume of trades in a short period of time—usually within seconds. A High Frequency Trader uses advanced technological innovations to get information faster than anyone else in the market.

During that interval a high-frequency trader could buy hundreds of millions of euros in London then sell them near-instantaneously in New York, making two cents off each one. Hypothetically say it takes 0.5 seconds for the market in New York to reflect that change, so for that half a second the price of a euro is two cents more expensive in New York than in London. The Securities and Exchange Commission and the Commodity Futures Trading Commission issued a joint report saying that high-frequency trading contributed to the volatility during and after the crash.
