Order Audit Trail System - OATS

Definition of 'Order Audit Trail System - OATS'


An automated computer system owned by the National Association of Security Dealers (NASD) that is used to record information relating to orders, quotes and other related trade information from all equities that are traded on the Nasdaq, including over the counter (OTC) stocks. This system simplifies an order's progression from the initial receipt of the order to its eventual execution or cancellation, so that it can be easily tracked for auditing purposes.

Investopedia explains 'Order Audit Trail System - OATS'


The NASD created OATS to ensure that the time sensitive information relating to the events throughout the order execution process is recorded accurately.

For example, according to NASD rule 6953, all "computer clocks and timestamping devices must be synchronized to be within three seconds of the National Institute of Standards and Technology atomic clock". (This atomic clock is highly accurate; it will not gain or lose one second of time in more than 60 million years)

  1. XW

    A symbol used to signify that a security is trading ex-warrant. XW is one of many alphabetic qualifiers that act as a shorthand to tell investors key information about a specific security in a stock quote. These qualifiers should not be confused with ticker symbols, some of which, like qualifiers, are just one or two letters.
  2. Quanto Swap

    A swap with varying combinations of interest rate, currency and equity swap features, where payments are based on the movement of two different countries' interest rates. This is also referred to as a differential or "diff" swap.
  3. Genuine Progress Indicator - GPI

    A metric used to measure the economic growth of a country. It is often considered as a replacement to the more well known gross domestic product (GDP) economic indicator. The GPI indicator takes everything the GDP uses into account, but also adds other figures that represent the cost of the negative effects related to economic activity (such as the cost of crime, cost of ozone depletion and cost of resource depletion, among others).
  4. Accelerated Share Repurchase - ASR

    A specific method by which corporations can repurchase outstanding shares of their stock. The accelerated share repurchase (ASR) is usually accomplished by the corporation purchasing shares of its stock from an investment bank. The investment bank borrows the shares from clients or share lenders and sells them to the company.
  5. Microeconomic Pricing Model

    A model of the way prices are set within a market for a given good. According to this model, prices are set based on the balance of supply and demand in the market. In general, profit incentives are said to resemble an "invisible hand" that guides competing participants to an equilibrium price. The demand curve in this model is determined by consumers attempting to maximize their utility, given their budget.
  6. Centralized Market

    A financial market structure that consists of having all orders routed to one central exchange with no other competing market. The quoted prices of the various securities listed on the exchange represent the only price that is available to investors seeking to buy or sell the specific asset.
