Tabb Group defines HFT as referring to fully-automated trading strategies in equities, derivatives, or currencies that seek to benefit from market liquidity imbalances or other short-term pricing inefficiencies. While these strategies can be employed overnight, most HFT strategies attempt to be market-neutral or closed out by the end of each day. Most HFT strategies employ algorithms to generate trading signals and manage orders, but not all algorithmic trading is high- frequency.
An important point is that there is no one, specific HFT strategy since high frequency traders vary widely in their approach to trading. However, in essence they look at all trading signals - from demand and supply on the order book to external factors - to judge the short term future value of an instrument and adjust their own prices accordingly.
This means that they are looking for a smaller margin before closing out the position, thus making their flow attractive for other non HFT flow to interact with so by fulfilling the liquidity needs of others. We believe high frequency trades often use spread capture and arbitrage strategies including statistical arbitrage trading , momentum trading , cross asset arbitrage and ETF to underlying arbitrage.
However there are also models that are operating on the aggressive side i. Please provide evidence on the amount of European trading executed by HF traders including the source s of that information.
Note that this covers order book executions in our London trading sectors in respect of cash equities including the International Order Book and structured products including ETFs and ETCs. Note that if all IDEM listed products are taken into consideration, the market share of HFT firms decreases substantially as their activity is nil on stock futures and quite limited on both FTSE MIB and equity options where most of the trading is done by market makers and institutional brokers.
This may increase costs - because of the way that clearing and settlement charging is structured see our response to question 7. The vast majority are direct one uses a form of Sponsored Access — see section II below.
For Turquoise, we consider 10 member firms to be HFT firms. However, most of these clients are trading both LSE equity markets as well as Italian equity and derivatives markets, so there is overlap.
However, for many of our member firms, particularly investment banks, some of their trading volumes may be related to HFT strategies originating within the member or by customers executing through the member. Hence our statistics on the market shares of HFT strategies are very conservative. If possible, please distinguish between HFT on transparent organised trading platforms and on dark pools of liquidity. In relation to organised and transparent derivatives markets, the percentage of market share attributable to High Frequency Trading is low compared to that 4 experienced in the underlying cash markets.
Derivative contracts that are attractive to high frequency traders are those contracts with a large number of participants, high volatility and a high level of liquidity.
Such contracts are most likely to be Index Future contracts, and will likely have tight spreads, enabling high frequency traders to get in and out of positions frequently, and achieve a flat end of day position. Currently the opinion is that as HFT makes up a small but growing percentage of market share, it does not have an adverse effect on the quality of derivatives, and is more likely to add to market liquidity with the effect of providing investors with a better price picture.
However, we note that as competition increases in the derivative space and derivative markets become more fragmented, the likely increase in HFT in derivative markets could mean that we face similar issues as the equity markets have raised as described in other sections of this paper.
For example, market making strategies cannot be employed in systems with a single reference price. Consequently, HFT strategies account for a lower proportion of dark pool trading than they do in lit markets. What are the key drivers of HFT , and if any limitations to the growth of HFT The emergence of high frequency traders and HFT strategies is a natural evolution of electronic markets and also increased fragmentation of markets, which requires a certain type of customer that brings the prices across different venues back together and serves to keep them aligned see our response to question 5.
The key drivers are increased technological capacity and reduced cost in trading and post- trading. Interoperability of CCPs has allowed efficiencies in the arbitrage of different products and reduced the cost of putting those arbitrage strategies in place.
As trading and associated post-trade costs fall, previously unprofitable trading strategies become marginally profitable, as the capturing of ever-smaller price movements in stocks becomes viable.
For such strategies to generate meaningful returns, they must be executed in high volume, and to control risks, positions are not typically held for a long time.
Hence HFT strategies will represent a higher proportion of market volumes as the costs of trading , particularly in post trade, reduce further. In your view, what is the impact of high frequency trading on the market, particularly in relation to: 5 - market structure e.
So far, the markets have set minimum tick sizes and this has worked efficiently. See section V below on tick sizes. The graph below shows LSE order book spreads.

Algorithmic Trading in Practice
High-frequency trading HFT is a type of algorithmic financial trading characterized by high speeds, high turnover rates, and high order-to-trade ratios that leverages high-frequency financial data and electronic trading tools. A substantial body of research argues that HFT and electronic trading pose new types of challenges to the financial system. High-frequency trading has taken place at least since the s, mostly in the form of specialists and pit traders buying and selling positions at the physical location of the exchange, with high-speed telegraph service to other exchanges. On September 2, , Italy became the world's first country to introduce a tax specifically targeted at HFT, charging a levy of 0. The high-frequency strategy was first made popular by Renaissance Technologies  who use both HFT and quantitative aspects in their trading.
Given recent requirements for ensuring the robustness of algorithmic trading strategies laid out in the Markets in Financial Instruments Directive II, this paper proposes a novel agent-based simulation for exploring algorithmic trading strategies. Five different types of agents are present in the market. The statistical properties of the simulated market are compared with equity market depth data from the Chi-X exchange and found to be significantly similar. The model is able to reproduce a number of stylised market properties including: clustered volatility, autocorrelation of returns, long memory in order flow, concave price impact and the presence of extreme price events. The results are found to be insensitive to reasonable parameter variations. Over the last three decades, there has been a significant change in the financial trading ecosystem.
Testimony on Regulatory Reforms to Improve Equity Market Structure
Disrupting Finance pp Cite as. Using a thematic analysis, the main themes developed within this research stream are identified and insights on the evolution of theory in relation to HFT are presented. The analysis also suggests that many open questions remain unanswered including more recent HFT trading strategies and complex techniques applied to analyse the content of both voluntary and mandatory corporate disclosure. The chapter concludes with a discussion of future trends and areas for research on HFT.
We study empirically how competition among high-frequency traders HFTs affects their trading behavior and market quality. Our analysis exploits a unique dataset, which allows us to compare environments with and without high-frequency competition, and contains an exogenous event - a tick size reform - which we use to disentangle the effects of the rising share of high-frequency trading in the market from the effects of high-frequency competition. We find that when HFTs compete, their speculative trading increases. As a result, market liquidity deteriorates and short-term volatility rises. Our findings hold for a variety of market quality and high-frequency trading behavior measures.
