High-frequency trading became commonplace in the markets following the introduction of incentives offered by exchanges for institutions to add liquidity to the markets. When one big sell-off occurs, HFT traders using similar strategies sell off as well with dangerous implication for markets. HFT can give traders an unfair advantage if they engage in market manipulation. Although it makes things easier, HFT (and what is hft other types of algorithmic trading) does come with drawbacks—notably the danger of causing major market moves, as it did in 2010, when the Dow suffered a large intraday drop. To begin high-frequency trading, you will need to develop an HFT algorithm and then translate it into machine language using one or more programming languages.
High-frequency trading: spreads and liquidity
The amount and volume of the trades using this strategy ensure a liquid market. HFT traders act as makeshift market makers who buy and sell when no one will. Currently, especially for highly followed companies, it is relatively simple to buy or sell a reasonably large amount of shares. Large investors, such as institutional investors, may choose to trade in dark pools to reduce the risk of their large orders influencing the markets in ways that could prove costly to them. Though some investors initially sought to trade in dark pools to avoid doing business with high-frequency trading firms, HFT firms ultimately emerged as major providers of liquidity in some private platforms. In this study in mid-2015, we did not find sufficient evidence to suggest that HFT practices have created dramatic new and strong forces to transform the regional markets of the Asia Pacific https://www.xcritical.com/ region.
High-frequency trading and the new market makers
These are private exchanges where institutional investors trade large volumes with one another without having to disclose the details of the deal to the wider market. This also means the transactions conducted in dark pools bypasses the servers feeding the data used by the algorithms established by high-frequency traders. CFA Institute believes HFT is not inherently manipulative or fraudulent, but the application of this “tool” by firms may lead to manipulative or fraudulent activity. Such actions by HFTs should be addressed through existing antifraud and antimarket manipulation rules.

High-frequency Forex trading is still a significant part of the financial services industry, but it is not as dominant or innovative as it once was. Hedge funds and investment institutions execute strategies based on overall global economic conditions, building short and long positions in currencies, equity, futures markets, commodities, and bonds. For instance, a hedge fund might have short positions in its stock exchange and invest the capital in nations with growing economies – IF it appears that such countries are headed toward a recession.
For less liquid markets such as small-cap stocks the spreads on offer are typically much larger. High frequency trading (HFT), or systematic trading, is an automated trading platform used by large investment banks, hedge funds and institutional investors. The strategy that engages powerful computers and servers and the fastest connectivity technology to trade large numbers of orders at extremely high speeds. The systems use complex algorithms to analyze the markets and are able to spot emerging trends in a fraction of a second. By being able to recognize shifts in the marketplace, the trading systems send hundreds of baskets of stocks out into the marketplace at bid-ask spreads advantageous to the traders. Traders are able to use HFT when they analyze important data to make decisions and complete trades in a matter of a few seconds.
High-frequency traders can use dark pools to attain or dispose of their financial instruments when possible. For example, if an algorithm can buy on the bid and then sell to a dark pool at the midpoint, they net half the bid-ask spread, less their fees. If an algorithm has accumulated a position, a dark pool may provide an easy exit that does not affect the price. The debate reached a fever pitch after the so-called Flash Crash of May 6, 2010, when the Dow Jones Industrial Average dove some 700 points within minutes and then quickly recovered.

“As soon as we went away from centralised exchanges the specialist markets traders had to find ways to arbitrage across exchanges. The way to do that is electronically – so that’s really the birth of today’s HFT ̶ cross market trading. 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.
This brief period of extreme intraday volatility demonstrated the weakness of the structure and stability of U.S. financial markets, as well as the opportunities for volatility-focused HFT traders (Creswell 2010). Although a subsequent investigation by the SEC cleared high-frequency traders of directly having caused the Flash Crash, they were still blamed for exaggerating market volatility, withdrawing liquidity for many U.S.-based equities (Lewis 2014). The damage caused by HFT errors is not limited to specific trading firms themselves, but also may involve stock exchanges and the stability of the related financial market. On Friday, May 18, 2012, the social network giant, Facebook’s stock was issued on the NASDAQ exchange. This was the most anticipated initial public offering (IPO) in its history.
The Dow Jones Industrial Average went through its second biggest intraday point decline, cratering 99.5 points, within minutes. This was the second-largest intraday point swing between intraday high and intraday low, to that point, at 1,010.14 points. Stock prices, stock index futures, options and exchange traded funds (ETFs) experienced wild volatility and trading volumes spiked. Tick trading often aims to recognize the beginnings of large orders being placed in the market. For example, a large order from a pension fund to buy will take place over several hours or even days, and will cause a rise in price due to increased demand. An arbitrageur can try to spot this happening, buy up the security, then profit from selling back to the pension fund.
This allows the same companies to share market profits year after year and achieve their investment objectives. Then the Global Financial Crisis struck, many firms were forced to curtail investments in HFT trading strategies, and some went bankrupt. As a result, the share of high-frequency trading in the market began to decline and stopped at 50%. Investment banks, prop firms, and closed-end funds began investing in the development of HFT algorithms and hiring teams of professional programmers.
High-frequency trading is highly debated and charges have been levelled against many HFT firms for illegal activities. The argument for HFT is that, in most cases, it provides substantial trading volume and liquidity to the market. This means that retail traders are more likely to have someone to buy from or sell to when needed.
Thus, investors and regulators rightly worry about the opportunity for these types of illegal and unethical trading activity that HFT provides. HFT is commonly used by banks, financial institutions, and institutional investors. It allows these entities to execute large batches of trades within a short period of time. But it can result in major market moves and removes the human touch from the equation.
