Does Algorithmic Trading Improve Liquidity? does_algorithmic_trading_improve_liquidity.pdf
TECHNOLOGICAL CHANGE HAS REVOLUTIONIZED the way financial assets are traded. Every step of the trading process, from order entry to trading venue to back office, is now highly automated, dramatically reducing the costs incurred by intermediaries. By reducing the frictions and costs of trading, technology has the potential to enable more efficient risk sharing, facilitate hedging, improve liquidity, and make prices more efficient. This could ultimately reduce firms’ cost of capital.
Algorithmic trading (AT) is a dramatic example of this far-reaching technological change. Many market participants now employ AT, commonly defined as the use of computer algorithms to automatically make certain trading decisions, submit orders, and manage those orders after submission. From a starting point near zero in the mid-1990s, AT is thought to be responsible for as much as 73 percent of trading volume in the United States in 2009.Automation, Speed, and Stock Market Quality: The NYSE’s Hybrid : the book

very quickly by leveraging advanced technology and the associated extremely low latency rates.
Ever since its inception at the turn of the 21st century, the popularity and usage of high frequency trading has been growing at an astonishing rate globally, bringing about significant changes in the way capital market firms carry out their trades. The floor-based style of trading is gradually being phased out, as more and more firms adapt to this new style of automated trading.
While HFT has numerous advantages, it creates its own set of unique challenges. Due to a number of market events including the infamous ‘May 6th Flash Crash’1 in 2010, HFT has come under criticism, resulting in regulators from across the world putting forth proposals aimed at curbing current HFT practices.
The recent controversies and regulatory proposals surrounding HFT have made most market participants sit up and take notice. This paper introduces the concept and origin of HFT, its impact on the markets, and what has caused regulators to pay special attention to this form of trading. The paper also talks about how both new and existing HFT firms can potentially benefit by focusing on certain investments and capabilities.
High Frequency Traders: Angels or Devils? : High Frequency Traders - Angels or Devils.pdf
Are high frequency traders angels or devils in terms of the impact on capital markets? Critics claim the latter and charge that they put retail and institutional investors at a disadvantage. Critics also blame high frequency trading for the “flash crash” on the Dow of May 6 2010 and say it has increased the likelihoodof such events happening again. A closer examination of these views is in order.
In this Commentary, I first look at what HF traders do and how HFT differs from traditional market making. I then explore the empirical evidence relating to the effect of HFT on capital markets, and canvass the policy issues that HFT raises. In the final section, I list some recommendations for policymakers with respect to HFT.
After surveying empirical studies of HFT, I conclude that it enhances market quality. For example, it lowers bid/ask spreads, reduces volatility, improves short-term price discovery, and creates competitive pressures that reduce broker commissions. Despite being at a pronounced speed disadvantage, retail traders have realized a net gain from the presence of HF traders in the world’s capital markets.
Maintain the Order Protection Rule and Contain the Spread of Dark Pools: To prevent abusive trading practices, protect client interests, and create a level playing field among different trading venues, policymakers should defend the consolidated order book by maintaining and policing the order protection rule and minimizing the leakage of trading from the “lit” markets to “dark pools.”
Do Not Interfere with Maker/Taker Pricing Models: Some observers say maker/taker pricing raises higher trading costs for retail traders, because retail trade orders are typically on the active side of the market, and associated fees are passed on to customers. However, retail traders are about as likely to be on the active as the passive side of the market. Maker/taker pricing may raise costs on the margin, but also lowers bid/ask spreads.
Focus on Circuit Breakers to Prevent “Flash Crashes”: HF traders did not cause the “flash crash,” and instead supply liquidity when markets become volatile. Canadian regulators concerned with preventing similar events should focus on circuit breakers to stop market anomalies before they turn into “flash crashes.”
