Gozluklu et al. However, this field is now clearly a future area of research as execution speed is the cornerstone of HFT. The minimum resting time indicates the minimum amount of time an order must stay in a limit order book to remain valid. Critics of this proposal argue that orders subject to a minimum resting time are exposed to higher risk and therefore introducing a minimum resting time would induce traders to widen the spreads. Conclusion Some concluding remarks The purpose of this literature review was to discuss the studies which investigate the effect of tick size changes on two main aspects of exchanges: market structure and market quality indicators.

This would help to enhance the Commission's ability to identify large and high-frequency traders and their affiliates. With that, we believe that policy regulators are becoming more concerned with how certain policies affect certain areas of the market; future research on tick size changes will identify how market structure is clearly associated with each one of these market segments. An obvious way to present the papers in this literature review is in a chronological order.

We therefore present the empirical papers in the field with the intention to inform the reader of a possible future topic for research. Why the choice to focus on market structure and market quality? Int Rev Financ Anal — High frequency trading may also help to reduce market spreads.

However, one stream of the literature is also concerned with the effect of this reduction to quoted depth and the ability of the market to absorb large trades. As we will discuss in Sect.

Introduction

Competition among markets has increased dramatically, especially in recent years. Similarly, a group of studies use odd-lot trading as a proxy for individual investor trading and investigate its effect on market anomalies based on time of the week or time of the year.

In a report for the UK Government Office for Science, Farmer and Skouras discuss the economic implications of the proposed minimum resting time regulations on exchanges. As a preliminary matter, let me describe ATSs and their origin , since certain types of ATSs figure prominently in market structure issues that I will discuss in a moment. One of the main findings is the steady decline in the proportion of odd-lot trading in the period considered. Consistent with the view that companies reduce the MTU in order to increase the investor base, the results show an increase in the number of individual investors after the MTU reductions. Possible future research topics In this review, we have identified several areas for future research. Search SpringerLink Search. The ability to have a method for connecting investors desiring to trade shares in large blocks could enable those investors to trade efficiently in sizes much larger than the average size of trades in the public markets.

However, a stream of the literature is also concerned with the effect of this reduction on quoted depth and the ability of the market to absorb large trades. Pac Account Rev — For example, Fang et al. In this section, we discuss the empirical literature on a subject closely related to the minimum tick size regulations. A further area of interest originates from the interaction of HFT with alternative trading systems or dark pools. To this end, we are concerned with the effect of tick size changes on the price discovery process, market making and market quality indicators. However, regarding dealer markets, Bessembinder argues that the relationship between tick size and market quality is relatively more complex than is hypothesized. They don't know which ATS executed the trade, or even whether it was executed in a dark pool at all. From a theoretical perspective, Buti et al. Looking at overall U. We subsequently focus on the implications of a change in tick size on market design and also on the interaction between market players, especially between retail and institutional investors.

Chordia and Subrahmanyam demonstrate that the existence of a finite minimum tick leads naturally to a curtailing of competition via the payment-for-order-flow practices. The authors argue that microstructure characteristics, such as the tick size, are endogenous to market structure; that is the difference between an auction and a dealer market. We subsequently focus on the implications of a change in tick size on market design and also on the interaction between market players, especially between retail and institutional investors. Goldstein et al. In most stock exchanges the MTU is equal to one share.

Related to the research on the MTU, a handful of studies examine the effects and the sources of odd-lot trading; these papers mostly focus on the US markets. The flashing of order information could lead to a two-tiered market in which the public does not have access, through the consolidated quotation data streams, to information about the best available prices for U. Many are concerned, however, that high frequency trading can be harmful, depending on the trading strategies used, both to the quality of the markets and the interests of long-term investors. Working paper, Kansas State University. In September, the SEC proposed to prohibit the practice of flashing marketable orders. In addition, the recipients of the flashed order can trade at the same price as the displayed quote without publicly quoting themselves. J Financ Econ — Footnote 8.

Four of these ATSs have chosen to publicly display their best orders in the consolidated quote stream as exchanges do and to allow their quotes to be accessed at least indirectly by any investor. The question is therefore, do minimum tick size changes make market making more profitable? What is of particular interest to changes in the minimum tick size and market structure is the relationship between the former, and market making activities.

Although these types of systems have existed since the late s, they began to proliferate in the mid s in response to technological developments that made it easier for broker-dealers to match buy and sell orders. Jones and Lipson show that the move to a smaller tick size increases execution costs for institutional investors.

This was primarily the case in the US markets since —that is, since the adoption of decimal pricing that slashed costs in terms of a reduction in bid—ask spreads. In this section, we discuss the empirical literature on a subject closely related to the minimum tick size regulations.

Another market structure issue that the Commission staff is exploring is sponsored access — also known as "direct market access" or "DMA" — where broker-dealer members of an exchange allow non-members — in many cases, high frequency traders — to trade on that exchange under their name. Chan and Hwang argue that market quality increases on a limit order book market after the tick size decrease. One of the main findings is the steady decline in the proportion of odd-lot trading in the period considered.

On a related note, Koznan and Tham argue that minimum trade size restrictions may take out arbitrageurs in a high frequency environment.

Another type of ATS is the so-called dark pool. A limited number of published papers use mutual fund data see Bollen and Busse or data from derivatives exchanges see ap Gwilym et al. Therefore, our paper is different from previous studies on the effect of decimalization on trading costs as our goal is to synthesize the literature with market structure and market quality in mind. Sponsored access could raise concerns about whether sponsoring broker-dealers impose appropriate and effective controls on sponsored access to fully protect themselves and the markets as a whole from financial risk, and to assure compliance with all regulatory requirements. ATSs are broker-dealers that match the orders of multiple buyers and sellers according to established, non-discretionary methods. Given that HFTRs are more active in a small-tick size environment, future research needs to look in more detail how HFTRs interact with other investors in markets where the tick size is relatively large and in different market structures. As we will discuss in Sect. The Commission's job is to make sure that the core principles of the Exchange Act — fairness, efficiency, and best execution — are maintained as the markets, and the environment in which they operate, change.
