For arbitrage traders, this creates a small window of opportunity to buy and sell shares that will be added to, or removed from, index funds. Index arbitrage strategies are based on exploiting periods where pension funds and investment firms rebalance their offerings on global indices to ensure they reflect the underlying index accurately.

Arbitrage is when you take advantage of the same asset having two different prices. For example, say in Town A soda sells for $1 per bottle while in Town B soda sells for $1.10. You could buy soda in Town A, then travel to Town B and sell it for the elevated price.

More fully automated markets such as NASDAQ, Direct Edge, and BATS, in the US, gained market share from less automated markets such as the NYSE. Economies of scale in electronic trading contributed to lowering commissions and trade processing fees, and contributed to international mergers and consolidation of financial exchanges. Index arbitrage exploits index tracker funds which are bound to buy and sell large volumes of securities in proportion to their changing weights in indices. If a HFT firm is able to access and process information which predicts these changes before the tracker funds do so, they can buy up securities in advance of the trackers and sell them on to them at a profit. Even the liquidity HFT creates only lasts a few seconds, so it’s often dubbed ‘ghost liquidity’ as it has no real benefit to most market participants, yet large firms receive fees from exchanges for the service. High-frequency trading (HFT) is a practice used to execute large orders quickly and take advantage of market inefficiencies.

  1. High-frequency trading is a growing phenomenon in the financial world, but it’s been around for several years.

  5. We briefly discuss below 10 key HFT terms that we believe are essential to gain an understanding of the subject.

Going by the name, high frequency means a high number of trades, maybe hundreds, thousands, or millions of stocks executed in fractions of seconds. High-Frequency Trading (HFT) is a process wherein computers are programmed to trade hundreds and thousands of times a second to make little profits over time. Decisions happen in milliseconds, and this could result in big market moves without reason.

Since the differences are typically small, trading may lead to a small profit. High-frequency trading allows this process to happen more quickly, advocates say, letting buyers and sellers meet each other’s’ bid and ask prices far more often than they would otherwise. However, if they can’t connect, Peter will reduce his price in order to find a buyer, selling Stock A for $9.50, candlestick chart excel arguably less than its actual market value. There are many strategies employed by the propriety traders to make money for their firms; some are quite commonplace, some are more controversial. Prior to the Volcker Rule, many investment banks had segments dedicated to HFT. Post-Volcker, no commercial banks can have proprietary trading desks or any such hedge fund investments.

What are some benefits of high-frequency trading?

It involves using computer algorithms to place trades at a very high rate of speed, often within a fraction of a second. This enables larger profits when done correctly, but it also comes with many risks that can result in massive losses. Because high-frequency traders use sophisticated algorithms to analyze data from various sources, they can find profitable price patterns and act fast. In 1987, high-frequency trading was linked to the “Black Monday” stock market crash that erased 22.6% from the Dow Jones Industrial Average, the biggest one-day percentage loss in history. As is often the case with market crashes, no single factor was responsible for the downturn.

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. High-frequency traders are said to contribute vital liquidity to markets, helping narrow bid/ask spreads and bringing buyers and sellers together efficiently. HFT is believed to provide liquidity to the market by acting as a makeshift market maker. With their high volume of trades, HFT traders facilitate opposite orders for buy or sell orders, ensuring that traders and investors can find a counterparty for their trades at any time. It appears that HFT has been around for a long time, even right from the time when pit trading was the only thing.

Common strategies used in high-frequency trading

Critics also object to HFT’s “phantom liquidity” (which refers to its ability to appear and disappear quickly), arguing that it makes markets less stable. Phantom liquidity is one of the outcomes of low-latency activities in high-speed friendly exchange structures. It emerges when a single trader — an HFT specifically — places duplicate orders in multiple venues.

Customers must read and understand the Characteristics and Risks of Standardized Options before engaging in any options trading strategies. Options transactions are often complex and may involve the potential of losing the entire investment in a relatively short period of time. Certain complex options strategies carry additional risk, including the potential for losses that may exceed the original investment amount. High-frequency uses computer programs and artificial intelligence to automate trading. This method relies on algorithms to analyze different markets and identify investing opportunities. And automation makes it possible for large trading orders to be executed in only fractions of a second.

For this to happen, banks and other financial institutions invest fortunes on developing superfast computer hardware and execution engines in the world. The precision of signals (buy/sell signals) is paramount since gains may quickly turn to losses if signals are not transferred rightly. So, HFT makes sure that every signal is precise enough to trigger trades at such a high level of speed.

The bid price represents the highest price a buyer is willing to pay, while the ask price is the lowest price a seller is willing to accept. By placing orders close to the current bid and ask prices, HFT firms facilitate trading and help ensure there is always a market available for buyers and sellers. High-frequency trading strategies may use properties derived from market data feeds to identify orders that are posted at sub-optimal prices. Such orders may offer a profit to their counterparties that high-frequency traders can try to obtain.

For example, say it takes 0.5 seconds for the New York market to update its prices to match those in London. For half of a second, euros will sell for more in New York than they do in London. This is more than enough time for a computer to buy millions of dollars’ worth of currency in one city and sell it for a profit in the other. High-frequency trading allows the investor to capitalize on opportunities that only exist for a short moment in the stock market. It also lets them be first to take advantage of those opportunities before prices have a chance to respond. Thus, these firms indulge in “market-making” only to make profits from the difference between the bid-ask spread.

So what looks to be perfectly in sync to the naked eye turns out to have serious profit potential when seen from the perspective of lightning-fast algorithms. The deeper that one zooms into the graphs, the greater price differences can be found between two securities that at first glance look perfectly correlated. There are several trading strategies that are adopted under high-frequency trading.
