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.
In financial services, a broker-dealer is a natural person, company or other organization that engages in the business of trading securities for its own account or on behalf of its customers. Broker-dealers are at the heart of the securities and derivatives trading process.
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 that widely disseminates orders entered by market makers to third parties and permits the orders to be executed against 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.
The Securities Investor Protection Corporation is a federally mandated, non-profit, member-funded, United States government corporation created under the Securities Investor Protection Act (SIPA) of 1970 that mandates membership of most US-registered broker-dealers. Although created by federal legislation and overseen by the Securities and Exchange Commission, the SIPC is neither a government agency nor a regulator of broker-dealers. The purpose of the SIPC is to expedite the recovery and return of missing customer cash and assets during the liquidation of a failed investment firm.
Front running, also known as tailgating, is the practice of entering into an equity (stock) trade, option, futures contract, derivative, or security-based swap to capitalize on advance, nonpublic knowledge of a large ("block") pending transaction that will influence the price of the underlying security. In essence, it means the practice of engaging in a personal or proprietary securities transaction in advance of a transaction in the same security for a client's account. Front running is considered a form of market manipulation in many markets. Cases typically involve individual brokers or brokerage firms trading stock in and out of undisclosed, unmonitored accounts of relatives or confederates. Institutional and individual investors may also commit a front running violation when they are privy to inside information. A front running firm either buys for its own account before filling customer buy orders that drive up the price, or sells for its own account before filling customer sell orders that drive down the price. Front running is prohibited since the front-runner profits come from nonpublic information, at the expense of its own customers, the block trade, or the public market.
All or none (AON) is a finance term used in investment banking or securities transactions that refers to "an order to buy or sell a stock that must be executed in its entirety, or not executed at all". Partial execution is not acceptable; the order will execute "only if there are enough shares available in a single transaction to cover it".
An order is an instruction to buy or sell on a trading venue such as a stock market, bond market, commodity market, financial derivative market or cryptocurrency exchange. These instructions can be simple or complicated, and can be sent to either a broker or directly to a trading venue via direct market access. There are some standard instructions for such orders.
Direct market access (DMA) is a term used in financial markets to describe electronic trading facilities that give 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.
Regulation National Market System is a 2005 US financial regulation promulgated and described by the Securities and Exchange Commission (SEC) as "a series of initiatives designed to modernize and strengthen the National Market System for equity securities". The Reg NMS is intended to assure that investors receive the best (NBBO) price executions for their orders by encouraging competition in the marketplace. Some contend that the rule has contributed to the rise of high-frequency trading, which is sometimes regarded as controversial.
An automated trading system (ATS), a subset of algorithmic trading, uses a computer program to create buy and sell orders and automatically submits the orders to a market center or exchange. The computer program will automatically generate orders based on predefined set of rules using a trading strategy which is based on technical analysis, advanced statistical and mathematical computations or input from other electronic sources.
The Financial Industry Regulatory Authority (FINRA) is a private American corporation that acts as a self-regulatory organization (SRO) that regulates member brokerage firms and exchange markets. FINRA is the successor to the National Association of Securities Dealers, Inc. (NASD) as well as to the member regulation, enforcement, and arbitration operations of the New York Stock Exchange. The U.S. government agency that acts as the ultimate regulator of the U.S. securities industry, including FINRA, is the U.S. Securities and Exchange Commission (SEC).
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.
The National Market System (NMS) is a regulatory mechanism that governs the operations of securities trading in the United States. Its primary focus is ensuring transparency and full disclosure regarding stock price quotations and trade executions. It was initiated in 1975, when, in the Securities Acts Amendments of 1975, Congress directed the Securities and Exchange Commission (SEC) to use its authority to facilitate the establishment of a national market system. The system has been updated periodically, for example with the Regulation NMS in 2005 which took into account technological innovations and other market changes.
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. It is a controversial practice that has been called a "kickback" by its critics. Policymakers supportive of PFOF and several people in finance who have a favorable view of the practice have defended it for helping develop new investment apps, low-cost trading, and more efficient execution.
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.
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.
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.
Smart order routing (SOR) is an automated process of handling orders, aimed at taking the best available opportunity throughout a range of different trading venues.
DEGIRO is a European brokerage company based in Amsterdam. It was founded in 2008 by a group of five former employees of Binck Bank to service the professional market. In 2013, DEGIRO started offering its stockbrokerage services to retail investors, which gives them online access to security exchanges.

Securities market participants in the United States include corporations and governments issuing securities, persons and corporations buying and selling a security, the broker-dealers and exchanges which facilitate such trading, banks which safe keep assets, and regulators who monitor the markets' activities. Investors buy and sell through broker-dealers and have their assets retained by either their executing broker-dealer, a custodian bank or a prime broker. These transactions take place in the environment of equity and equity options exchanges, regulated by the U.S. Securities and Exchange Commission (SEC), or derivative exchanges, regulated by the Commodity Futures Trading Commission (CFTC). For transactions involving stocks and bonds, transfer agents assure that the ownership in each transaction is properly assigned to and held on behalf of each investor.
