The result was the Regulation National Market System, otherwise known as Reg NMS, which was authored by many industry participants in collaboration with the SEC. Proposed in late 2004, Reg NMS was supposed to serve as the framework for the evolving stock markets for the coming century. Due to delays, lobbying, industry comment letters, and reworking, it wasn’t implemented until late 2007. Reg NMS created the concept of a National Best Bid and Offer (NBBO). The NBBO was an aggregation of the best priced orders on all exchanges and ECNs, and it was protected. This meant that if one market center, say the NYSE, had a participant with an order to buy stock at $10.00 and did not have a matching sell order at $10.00, while another exchange, say NASDAQ, did, then the NYSE would have to route out that buy order to NASDAQ, which would then match the buy and sell order.

These exchanges also are responsible for maintaining the publicly available stock quotes, commonly called the Security Information Processor (SIP). This is the quote that most investors see when they look at their data terminals, or if they watch quotes stream on their online broker’s website. It is also the speed that the national best bid and offer (NBBO) updates for most dark pools, although not all. (Dark pools contain trading that is not generally available to the public: the orders and quotes in them are not visible like an exchange’s quotes are.) The SIP speed is slower than the speed of the exchanges’ direct data feeds, which are sold to collocating HFT firms so they can act on the data faster than anybody else.

Rigged Money: Beating Wall Street at Its Own Game

In other words, in the end the volume is reported, but you can’t tell what ATS executed which trade. While ATSs don’t display real-time prices and size publicly, which makes them dark, they derive their pricing from the national best bid and offer (NBBO). All trades have to occur inside or at the NBBO price. Don’t forget that ATSs are highly regulated by the SEC. national best bid and offer (NBBO) A requirement by the SEC that requires brokers to execute trades at the best buy or sell price. It is also the quote that most people see when looking up a stock price. This is the best buy and sell price offered publicly.

Who pays for this? Professional traders. Each month my hedge fund writes a check to several different tape services. If you want to trade, you have to pay for the infrastructure. Part of the evolution of electronic trading is ensuring these lightning-fast trades are executed at what the SEC calls the National Best Bid and Offer. NBBO is a calculation, not an organization. Consolidated Tape Association (CTA), Consolidated Quotation System (CQS), Options Price Reporting Authority (OPRA), and Over-the-Counter (OTC) are all organizations that provide consolidated tape for stocks and options. Without them, there would be no central depository of price information.

Flash Boys: A Wall Street Revolt
by Michael Lewis
Published 30 Mar 2014

He had the discretion not to spook the market, and to play your hand on your behalf as smartly as he could. After the brokers abused the trust implicit in that discretion once too often, the government took the discretion away. Reg NMS replaced the loose notion of best execution with the tight legal one of “best price.” To define best price, Reg NMS relied on the concept of the National Best Bid and Offer, known as the NBBO. If an investor wished to buy 10,000 shares of Microsoft, and 100 shares were offered on the BATS exchange at $30 a share, while the full 10,000 listed on the other twelve exchanges were offered at $30.01, his broker was required to purchase the 100 shares on Bats at $30 before moving on to the other exchanges.

The regulation also made it far easier for high-frequency traders to predict where brokers would send their customers’ orders, as they must send them first to the exchange that offered the best market price. That would have been fine but for the manner in which the best market price was calculated. The new law required a mechanism for taking the measure of the entire market—for creating the National Best Bid and Offer—by compiling all the bids and offers for all U.S. stocks in one place. That place, inside some computer, was called the Securities Information Processor, which, because there is no such thing on Wall Street as too many acronyms, became known as the SIP. The thirteen stock markets piped their prices into the SIP, and the SIP calculated the NBBO.

Three weeks later, a Nasdaq employee clicked the wrong icon on his computer screen and stopped the public offering of shares in a company called WhiteHorse Finance. In early January 2013, BATS announced that, because of some unspecified computer error, it had, since 2008, inadvertently allowed trades to occur, illegally, at prices worse (for the investor) than the National Best Bid and Offer. That was just a sampling from a single year of what were usually described as “technical glitches” in the new, automated U.S. stock markets: Collectively, they had experienced twice as many outages in the two years after the flash crash as in the previous ten. The technical glitches were accompanied by equally bewildering irregularities in stock prices.

High-Frequency Trading
by David Easley , Marcos López de Prado and Maureen O'Hara

Reg NMS was wildly successful at this, as the market structure of 13 equity exchanges and 40 or more alternative venues (dark pools, dealer desks, etc) attests. Cohesion was supposedly ensured in the US through a mechanism for the consolidation of individual orders processed via multiple venues (the “National Best Bid and Offer” (NBBO)).1 These changes, combined with decimalisation of equity markets, resulted in an “arms race” to develop the technology and quantitative methods that could extract the last cent of profitability from trading while serving the demands of market participants. The high-frequency strategies that developed are actually very diverse.

At what prices do the executions take place, since orders do not specify prices? As per the aforementioned motivation of liquidity over price (improvement), in general dark pool executions take place at the prevailing prices in the corresponding lit (limit order) market for the stock in question, eg, at the midpoint of the bid–ask spread, as measured by the National Best Bid and Offer (NBBO). Thus, while dark pools operate separately and independently of the lit markets, their prices are strongly tied to those lit markets. From a data and machine learning perspective, there are two crucial differences between dark pools and their lit market counterparts. (i) Unlike the microstructure data for the lit markets, in dark pools we have access only to our own order and execution data, rather than the entire trading population.

Similarly, Reg NMS encourages competitiveness among exchanges by allowing market fragmentation. Cohesion across markets is recovered through a mechanism for the consolidation of individual orders processed in multiple venues into a single best bid or offer price for the market as a whole (the National Best Bid and Offer (NBBO)). Since the arrival of trading in multiple markets, an “arms race” has developed for the technology and quantitative methods that can squeeze out the last cent of profitability when serving the demands of market participants, hence the advent of high-frequency trading. Easley et al (2011a) have argued that these changes are related to a number of new trends in market microstructure.

The Crisis of Crowding: Quant Copycats, Ugly Models, and the New Crash Normal

They never report the buyer or seller’s identity.5 Broker-dealers can route customer orders to the marketplace or internalize orders, using their own capital to settle customer trades. This is often more efficient and saves transaction costs. Broker-dealers must also report internalized trades to the consolidated tape. Stock exchange laws say that all trades must be executed at the national best bid and offer at the time of execution. This is true for exchanges, ECNs, dark pools, and broker-dealers. New technologies and interconnected trading systems have made trading much faster. Despite the high speeds and information flow, flash crashes have happened before. On May 3, 1906, and August 9, 1919, for instance, stock prices changed dramatically, then recovered.6 The modern trading system had some flashes as early as April 28, 2010.

A limit order is a stock order that includes the number of shares a trader would like to buy or sell at a given stock price or better. In a buy limit order at $12 per share, the order is only executed at a price of $12 or less. Otherwise, it isn’t executed at all. 11. This is known as the NBBO, or the national best bid and offer. A market maker is willing to buy the stock at $10 and another market maker will sell the stock at $10.02. The spread is compensation for the risk market makers take in providing liquidity. 12. Jim Angel, a professor at Georgetown University, used these terms in our conversations about trading. 13.

The Fear Index
by Robert Harris
Published 14 Aug 2011

The system is entirely automated and operates at a speed of thousandths of a second. To a professional such as Hoffmann, the CBOE Self Help alert gave warning that the New York electronic exchange ARCA was experiencing some kind of system breakdown – an interruption sufficiently serious that Chicago would no longer re-route orders to it under the National Best Bid and Offer (NBBO) regulations, even if it was offering better prices for investors than Chicago. The announcement had two immediate consequences. It meant Chicago had to step in and provide the liquidity formerly offered by NYSE/ARCA – at a time when liquidity was, in any case, in short supply – and it also, perhaps more importantly, further spooked an already jittery market.

Trading and Exchanges: Market Microstructure for Practitioners
by Larry Harris
Published 2 Jan 2003

Traders also call them the market bid and the market offer (or market ask) because they are the best prices available in the market. A market quotation reports the best bid and best offer in a market. A market quotation is often called the BBO, which is the acronym for Best Bid and Offer. Many markets continuously publicize their market quotations. The best bid and offer anywhere in the United States is the NBBO—National Best Bid and Offer. The difference between the best ask and the best bid is the bid/ask spread. Traders sometimes call it the inside spread because the space between the highest bid price and the lowest ask price is inside the market. The English often refer to the spread as the touch. In sports betting markets, bettors and bookies call it the vigorish.
