Zero-intelligence Trader
A zero-intelligence trader (ZI) is a simple algorithmic trader in a market based on the dumb agent theory who proposes to purchase (bid) or to sell (ask) randomly, subject only to minimal constraints. Constraints might be resource or bankruptcy constraints imposed externally by the rules of the market. Ownership of sufficient resources to buy the items the trader bids for, or ownership of resources the trader offers for sale are examples of such market-imposed constraints. Alternatively, the constraints may be internal to the trader. Not bidding more than the value of the resource to the trader, and not asking less than the cost of the resource to the trader are examples of such internal constraints. Under either interpretation, ZI traders use minimal intelligence in choosing their actions in markets.

Algorithmic Trading
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. It is widely used by investment banks, pension funds, mutual funds, and hedge funds that may need to spread out the execution of a larger order or perform trades too fast for human traders to react to. A study in 2019 showed that around 92% of trading in the Forex market was performed by trading algorithms rather than humans. The term algorithmic trading is often used synonymously with automated trading system. These encompass a variety of trading strategies, some of which are based on formulas and results from mathematical finance, and often rely on specialized software. Examples o ...

Market (economics)
In economics, a market is a composition of systems, institutions, procedures, social relations or infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services (including labour power) to buyers in exchange for money. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society. Markets allow any tradeable item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights (cf. ownership) of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale (local produce or stock registration). Markets can dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumb Agent Theory
The dumb agent theory (DAT) states that many people making individual buying and selling decisions will better reflect true value than any one individual can. In finance this theory is predicated on the efficient-market hypothesis (EMH). One of the first instances of the dumb agent theory in action was with the Policy Analysis Market (PAM); a futures exchange developed by DARPA. While this project was quickly abandoned by the Pentagon, its idea is now implemented in futures exchanges and prediction markets such as Intrade, Newsfutures and Predictify. The DAT is technically a hypothesis, not a theory. While first mentioned strictly by name in relation to PAM in 2003, the dumb agent theory was originally conceived (as the Dumb Smart Market) by James Surowiecki in 1999. Here, Surowiecki differentiated from the EMH stating that it "doesn't mean that markets are always right." Instead, he argues that markets are subject to manias and panics because "people are always shouting out" their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bankruptcy
Bankruptcy is a legal process through which people or other entities who cannot repay debts to creditors may seek relief from some or all of their debts. In most jurisdictions, bankruptcy is imposed by a court order, often initiated by the debtor. Bankrupt is not the only legal status that an insolvent person may have, and the term ''bankruptcy'' is therefore not a synonym for insolvency. Etymology The word ''bankruptcy'' is derived from Italian ''banca rotta'', literally meaning "broken bank". The term is often described as having originated in renaissance Italy, where there allegedly existed the tradition of smashing a banker's bench if he defaulted on payment so that the public could see that the banker, the owner of the bench, was no longer in a condition to continue his business, although some dismiss this as a false etymology. History In Ancient Greece, bankruptcy did not exist. If a man owed and he could not pay, he and his wife, children or servants were forced into " ...

Double Auction
A double auction is a process of buying and selling goods with multiple sellers and multiple buyers. Potential buyers submit their bids and potential sellers submit their ask prices to the market institution, and then the market institution chooses some price ''p'' that clears the market: all the sellers who asked less than ''p'' sell and all buyers who bid more than ''p'' buy at this price ''p''. Buyers and sellers that bid or ask for exactly ''p'' are also included. A common example of a double auction is stock exchange. As well as their direct interest, double auctions are reminiscent of Walrasian auction and have been used as a tool to study the determination of prices in ordinary markets. A double auction is also possible without any exchange of currency in barter trade. A barter double auction is an auction where every participant has a demand and an offer consisting of multiple attributes and no money is involved.
