Flash trading

Last updated

Flash trading, otherwise known as a flash order, is a marketable order sent to a market center that is not quoting the industry's best price or that cannot fill that order in its entirety. The order is then flashed to recipients of the venue's proprietary data feed to see if any of those firms wants to take the other side of the order.

Contents

This practice enables the market center to try to keep the trade since the firm that is seeking to buy or sell shares or stock posts the information only on a specific stock exchange before sending the trade information out on the broader public markets, and making it available to all potential investors. [1] [2] If a deal can be struck between recipients of the flash trade, the result is a locked market with guaranteed pricing on the order. On some trades, it also results in better profits for the firms making the trades, as the firms often get rebates or lower fees for flash trades when the transaction is completed internally and doesn't get posted on rival stock exchanges. [2] In 2009 in the United States under an exception to Rule 602 of Regulation NMS flash orders were allowed.

In high-frequency trading flash orders for small amounts are utilised to find large orders so that the high frequency trader can buy or sell all available stock before the large order reaches the rest of the market. This may be done within a dark pool or over a number of electronic exchanges where the speed of the order routing is critical to the success of the strategy. According to the US Securities and Exchange Commission (SEC) by 2009 this practice had become controversial, with some market participants saying that high frequency traders could use flash orders to unfairly exploit others and that it is akin to front running. [3]

History

According to a 2009 Bloomberg article:

Flash systems trace their roots as far back as 1978 to efforts by exchanges to electronically replicate how a trader might yell an order to floor brokers before entering it into the system that displays all bids and offers. Markets have evolved since the days of floor brokers’ dominance, with computer algorithms now buying and selling shares 1,000 times faster than the blink of an eye. [4]

In 2010 flash orders gained popularity in the options markets, where as early as 2000 the Chicago Board Options Exchange (CBOE) began using the particular type of order to help improve the speed of trade executions for its clients. [5]

In 2006, Direct Edge began offering customers the ability to flash orders in the equities market. Direct Edge quickly captured market share from their rivals as their share of matched trades soared from 1% of the industry's volume to 12%. [2] Direct Edge became a U.S. exchange in July 2010. [6] Nasdaq and BATS (U.S. exchanges) created their own flash market in early 2009 in response to the Direct Edge market. Both voluntarily discontinued the practice in August 2009. [7] [8]

Direct Edge's response to this in 2009 was that the data that flash trading used reduced market impact, increased average size of executed orders, reduced trading latency, and provided additional liquidity. Direct Edge also allowed all of its subscribers to determine whether they want their orders to participate in flash trading or not so brokers have the option to opt out of flash orders on behalf of their clients if they choose to. Because market participants can choose to utilize it for additional liquidity or not participate in it at all Direct Edge believes the controversy was overstated stating:

"Misconceptions respecting flash technology have, to date, stirred a passionate but ill informed debate." Direct Edge 2009 [9]

Debate

In 2009 critics argued that the practice was harmful to market transparency. Proponents of flash trading stated that it is necessary to provide liquidity for exchanges. [10]

Critics

In 2009 critics of the practice (notably high-frequency trading firm GETCO [11] ) contended this creates a two-tiered market in which a certain class of traders can unfairly exploit others, akin to front running.[ citation needed ] Exchanges in 2009 claimed that the procedure benefits all traders by creating more market liquidity and the opportunity for price improvement. However, a December 2009 article in The Banker noted:

in a bid to fuel the controversy and fill column space, however, several commentators and pundits have complained bitterly that flashes expose information that may allow traders to ‘front-run’ orders. The widespread perception, meanwhile, that flash orders are the preserve of hyper-sophisticated high-frequency traders has further cemented the misguided notion that the lay retail investor is in turn being cheated. [12]

Direct Edge's response to the "two-tiered market" criticism is as follows:

First it is difficult to address concerns that may result, particularly when there is no empirical data to support such as result. Furthermore, we do not view technology that instantaneously aggregates passive and aggressive liquidity as creating a two-tier market. Rather, flash technology democratizes access to the non-displayed market and in this regard, removes different "tiers" in market access. Additionally, any subscriber of Direct Edge can be a recipient of flashed orders.

The U.S. Securities and Exchange Commission in September 2009 [13] [14] [15] proposed banning the practice as part of regulatory reforms in the wake of the Financial crisis of 2007–2010. [16] [17] As of May 2010, the proposals have not been implemented. Even though most programs have been stopped voluntarily, it is still possible, at least with Direct Edge. [18]

Supporters

In 2009 Sang Lee, managing partner at Aite Group, an independent research firm in Boston, saw the debate about flash orders as more philosophical than practical. Since the total market volume that goes through flash orders accounted for only 2% to 3% of daily volume in 2009, there would not be a big change in trade volume among major players if those orders disappeared. [19]

In 2009 Bogoslaw predicted that regardless of the endgame, there would always be differences in the speed of information-technology capabilities of market centers and market participants. He argued that as long as market centers competed for order flow, investors can benefit, even if participating is only through investments in mutual or pension funds. In 2009 large institutional investors benefit directly by having enough liquidity to move a big block of shares with minimal price impact. [19]

<span class="mw-page-title-main">Day trading</span> Buying and selling financial instruments within the same trading day

Day trading is a form of speculation in securities in which a trader buys and sells a financial instrument within the same trading day, so that all positions are closed before the market closes for the trading day to avoid unmanageable risks and negative price gaps between one day's close and the next day's price at the open. Traders who trade in this capacity are generally classified as speculators. Day trading contrasts with the long-term trades underlying buy-and-hold and value investing strategies. Day trading may require fast trade execution, sometimes as fast as milli-seconds in scalping, therefore direct-access day trading software is often needed.

An electronic communication network (ECN) is a type of computerized forum or network that facilitates the trading of financial products outside traditional stock exchanges. An ECN is generally an electronic system accessed by an electronic trading platform that widely disseminates orders entered by market makers to third parties and permits the orders to be executed against them in whole or in part. The primary products that are traded on ECNs are stocks and currencies. ECNs are generally passive computer-driven networks that internally match limit orders and charge a very small per share transaction fee.

Algorithmic trading is a method of executing orders using automated pre-programmed trading instructions accounting for variables such as time, price, and volume. This type of trading attempts to leverage the speed and computational resources of computers relative to human traders. In the twenty-first century, algorithmic trading has been gaining traction with both retail and institutional traders. A study in 2019 showed that around 92% of trading in the Forex market was performed by trading algorithms rather than humans.

Direct market access (DMA) in financial markets is the electronic trading infrastructure that gives investors wishing to trade in financial instruments a way to interact with the order book of an exchange. Normally, trading on the order book is restricted to broker-dealers and market making firms that are members of the exchange. Using DMA, investment companies and other private traders use the information technology infrastructure of sell side firms such as investment banks and the market access that those firms possess, but control the way a trading transaction is managed themselves rather than passing the order over to the broker's own in-house traders for execution. Today, DMA is often combined with algorithmic trading giving access to many different trading strategies. Certain forms of DMA, most notably "sponsored access", have raised substantial regulatory concerns because of the possibility of a malfunction by an investor to cause widespread market disruption.

In finance, a dark pool is a private forum for trading securities, derivatives, and other financial instruments. Liquidity on these markets is called dark pool liquidity. The bulk of dark pool trades represent large trades by financial institutions that are offered away from public exchanges like the New York Stock Exchange and the NASDAQ, so that such trades remain confidential and outside the purview of the general investing public. The fragmentation of electronic trading platforms has allowed dark pools to be created, and they are normally accessed through crossing networks or directly among market participants via private contractual arrangements. Generally, dark pools are not available to the public, but in some cases, they may be accessed indirectly by retail investors and traders via retail brokers.

A multilateral trading facility (MTF) is a European Union regulatory term for a self-regulated financial trading venue. These are alternatives to the traditional stock exchanges where a market is made in securities, typically using electronic systems. The concept was introduced within the Markets in Financial Instruments Directive (MiFID), a European Directive designed to harmonise retail investors protection and allow investment firms to provide services throughout the EU.

In finance, an electronic trading platform, also known as an online trading platform, is a computer software program that can be used to place orders for financial products over a network with a financial intermediary. Various financial products can be traded by the trading platform, over a communication network with a financial intermediary or directly between the participants or members of the trading platform. This includes products such as stocks, bonds, currencies, commodities, derivatives and others, with a financial intermediary such as brokers, market makers, Investment banks or stock exchanges. Such platforms allow electronic trading to be carried out by users from any location and are in contrast to traditional floor trading using open outcry and telephone-based trading. Sometimes the term trading platform is also used in reference to the trading software alone.

Payment for order flow (PFOF) is the compensation that a stockbroker receives from a market maker in exchange for the broker routing its clients' trades to that market maker. The market maker profits from the bid-ask spread and rebates a portion of this profit to the routing broker as PFOF. Another fraction of a penny per share may be routed back to the consumer as price improvement.

High-frequency trading (HFT) is a type of algorithmic trading in finance characterized by high speeds, high turnover rates, and high order-to-trade ratios that leverages high-frequency financial data and electronic trading tools. While there is no single definition of HFT, among its key attributes are highly sophisticated algorithms, co-location, and very short-term investment horizons in trading securities. HFT uses proprietary trading strategies carried out by computers to move in and out of positions in seconds or fractions of a second.

The May 6, 2010, flash crash, also known as the crash of 2:45 or simply the flash crash, was a United States trillion-dollar flash crash which started at 2:32 p.m. EDT and lasted for approximately 36 minutes.

In modern finance, a flash crash is a very rapid, deep, and volatile fall in security prices occurring within a very short time period followed by a quick recovery. Flash crashes are frequently blamed by media on trades executed by black-box trading, combined with high-frequency trading, whose speed and interconnectedness can result in the loss and recovery of billions of dollars in a matter of minutes and seconds, but in reality occur because almost all participants have pulled their liquidity and temporarily paused their trading in the face of a sudden increase in risk.

In finance, quote stuffing refers to a form of market manipulation employed by high-frequency traders (HFT) that involves quickly entering and withdrawing a large number of orders in an attempt to flood the market. This can create confusion in the market and trading opportunities for high-speed algorithmic traders. The term is relatively new to the financial market lexicon and was coined by Nanex in studies on HFT behavior during the 2010 Flash Crash.

A fat-finger error is a keyboard input error or mouse misclick that occurs from a simple input mistake, causing unwanted secondary behavior. In common parlance, it simply refers to a common typographical error made on a touchscreen or physical keyboard that occurs when the wrong selection is made, or multiple selections are made due to options or keyboard keys being too close together.

Spoofing is a disruptive algorithmic trading activity employed by traders to outpace other market participants and to manipulate markets. Spoofers feign interest in trading futures, stocks, and other products in financial markets creating an illusion of the demand and supply of the traded asset. In an order driven market, spoofers post a relatively large number of limit orders on one side of the limit order book to make other market participants believe that there is pressure to sell or to buy the asset.

For three hours on August 22, 2013, trading was halted on the Nasdaq Stock Market. Trading on the exchange stopped at 12:14 pm and resumed at 3:25 pm, with 35 minutes left of trading for the day. One week after the trading halt NASDAQ OMX credited the freeze to an overloading of the Securities Information Processor (SIP) caused by reconnection issues with the New York Stock Exchange Arca. The freeze received substantial media coverage and generated discussions on the security of increasingly technologically advanced stock exchanges. The event coined the term "flash freeze" following the earlier "flash crash" on May 6, 2010.
