When Wall Street firms use algorithms, they simply encode logic on the computer. A trading algorithm can be fundamentally driven, that is, it is. Algorithmic trading is an automated trading approach that uses computer algorithms to trade the markets. These algorithms create buy and sell orders (when the appropriate conditions are met in each case) and send them automatically to the market through the brokerage platform.
In order for the trading algorithm to place an order, market conditions must match the predefined criteria for entering an order depending on the trading strategy on which the algorithm is based. Author Michael Lewis drew public attention to high-frequency algorithmic operations when he published the successful book Flash Boys, which documented the lives of Wall Street merchants and entrepreneurs who helped create the companies that defined the structure of e-commerce in the United States. An example of the importance of speed in publishing news for algorithmic operators was an advertising campaign by Dow Jones (the appearances included page W15 of The Wall Street Journal, dated March 1, 2000), in which it stated that its service had surpassed other news services by two seconds when reporting on a reduction in interest rates by the Bank of England.
