  2. Limit-preserving function (order theory) - Wikipedia

    en.wikipedia.org/wiki/Limit-preserving_function...

    Limit-preserving function (order theory) In the mathematical area of order theory, one often speaks about functions that preserve certain limits, i.e. certain suprema or infima. Roughly speaking, these functions map the supremum/infimum of a set to the supremum/infimum of the image of the set. Depending on the type of sets for which a function ...

    Besides these two most common order types, brokers may offer a number of other options, such as stop-loss orders or stop-limit orders. Order types differ by broker, but they all have market and ...

  4. Order matching system - Wikipedia

    en.wikipedia.org/wiki/Order_matching_system

    Large limit orders can be "front-run" by "penny jumping". For example, if a buy limit order for 100,000 shares for $1.00 is announced to the market, many traders may seek to buy for $1.01. If the market price increases after their purchases, they will get the full amount of the price increase.

  5. Order (exchange) - Wikipedia

    en.wikipedia.org/wiki/Order_(exchange)

    Limit orders are used when the trader wishes to control price rather than certainty of execution. A buy limit order can only be executed at the limit price or lower. For example, if an investor wants to buy a stock, but does not want to pay more than $30 for it, the investor can place a limit order to buy the stock at $30.

    Large limit orders can be "front-run" by "order matching" or "penny jumping".

  7. Rate of convergence - Wikipedia

    en.wikipedia.org/wiki/Rate_of_convergence

    t. e. In mathematical analysis, particularly numerical analysis, the rate of convergence and order of convergence of a sequence that converges to a limit are any of several characterizations of how quickly that sequence approaches its limit. These are broadly divided into rates and orders of convergence that describe how quickly a sequence ...

  8. Bid–ask spread - Wikipedia

    en.wikipedia.org/wiki/Bid–ask_spread

    The bid–ask spread (also bid–offer or bid/ask and buy/sell in the case of a market maker) is the difference between the prices quoted (either by a single market maker or in a limit order book) for an immediate sale (ask) and an immediate purchase (bid) for stocks, futures contracts, options, or currency pairs in some auction scenario.

  9. Big O notation - Wikipedia

    en.wikipedia.org/wiki/Big_O_notation

    Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.
