Early form of Automated Trading System has been used by financial managers and brokers, software based on algorithm. These kind of software were used to automatically manage clients' portfolios.
But first service to free market without any supervision from financial advisers and managers to serve clients directly was given in with the launch of Betterment by Jon Stein. Since then this system is getting improved with development in IT industry, now Automated Trading System is managing huge assets all around the globe. Trading strategies differ; some are designed to pick market tops and bottoms, others to follow a trend, and others involve complex strategies including randomizing orders to make them less visible in the marketplace.
ATSs allow a trader to execute orders much quicker and manage their portfolio easily by automatically generating protective precautions. Backtesting of a trading system involves programmers running the program using historical market data in order to determine whether the underlying algorithm guiding the system may produce the expected results. Developers can create backtesting software to enable a trading system designer to develop and test their trading systems using historical market data to optimize the results obtained with the historical data.
Although backtesting of automated trading systems cannot accurately determine future results, an automated trading system can be backtested using historical prices to see how the system theoretically would have performed if it had been active in a past market environment. Forward testing of an algorithm can also be achieved using simulated trading with real-time market data to help confirm the effectiveness of the trading strategy in the current market and may be used to reveal issues inherent in the computer code.
Live testing is the final stage of the development cycle. In this stage, live performance is compared against the backtested and walk forward results. The goal of an automated trading system is to meet or exceed the backtested performance with a high efficiency rating. Improved order entry speed allows a trader to enter or exit a position as soon as the trade criteria are satisfied.
Furthermore, stop losses and profit targets can be automatically generated using an automated trading system. Automated trading, or high-frequency trading, causes regulatory concerns as a contributor to market fragility.
United States regulators have published releases   discussing several types of risk controls that could be used to limit the extent of such disruptions, including financial and regulatory controls to prevent the entry of erroneous orders as a result of computer malfunction or human error, the breaching of various regulatory requirements, and exceeding a credit or capital limit.
The use of high-frequency trading HFT strategies has grown substantially over the past several years and drives a significant portion of activity on U. Although many HFT strategies are legitimate, some are not and may be used for manipulative trading. Given the scale of the potential impact that these practices may have, the surveillance of abusive algorithms remains a high priority for regulators.
The Financial Industry Regulatory Authority FINRA has reminded firms using HFT strategies and other trading algorithms of their obligation to be vigilant when testing these strategies pre- and post-launch to ensure that the strategies do not result in abusive trading.
FINRA continues to be concerned about the use of so-called "momentum ignition strategies" where a market participant attempts to induce others to trade at artificially high or low prices. Examples of this activity include layering and spoofing strategies where a market participant places a nonbona fide order on one side of the market typically, but not always, above the offer or below the bid in an attempt to bait other market participants to react to the non-bona fide order and trade with another order on the other side of the market.
FINRA also continues to focus concern on the entry of problematic HFT and algorithmic activity through sponsored participants who initiate their activity from outside of the United States.
FINRA conducts surveillance to identify cross-market, cross-product manipulation of the price of underlying equity securities, typically through abusive trading algorithms, and strategies used to close out pre-existing option positions at favorable prices or establish new option positions at advantageous prices.
In recent years, there have been a number of algorithmic trading malfunctions that caused substantial market disruptions. These raise concern about firms' ability to develop, implement and effectively supervise their automated systems. FINRA has stated that it will assess whether firms' testing and controls related to algorithmic trading and other automated trading strategies and trading systems are adequate in light of the U. Larger institutional clients, however, will generally place electronic orders via proprietary electronic trading platforms such as Bloomberg Terminal , Reuters Xtra , Thomson Reuters Eikon , BondsPro, Thomson TradeWeb or CanDeal which connect institutional clients to several dealers , or using their brokers' proprietary software.
For stock trading, the process of connecting counterparties through electronic trading is supported by the Financial Information eXchange FIX Protocol.
Used by the vast majority of exchanges and traders, the FIX Protocol is the industry standard for pre-trade messaging and trade execution. While the FIX Protocol was developed for trading stocks, it has been further developed to accommodate commodities,  foreign exchange,  derivatives,  and fixed income  trading. For retail investors, financial services on the web offer great benefits. The primary benefit is the reduced cost of transactions for all concerned as well as the ease and the convenience.
Webdriven financial transactions bypass traditional hurdles such as logistics. Conversely there is concern about the impact of speculation through trading, considered negatively and of potential significant damage to the real economy . Exchanges typically develop their own systems sometimes referred to as matching engines , although sometimes an exchange will use another exchange's technology e.
Exchanges and ECNs generally offer two methods of accessing their systems —. From an infrastructure point of view, most exchanges will provide "gateways" which sit on a company's network, acting in a manner similar to a proxy , connecting back to the exchange's central system. Many brokers develop their own systems, although there are some third-party solutions providers specializing in this area.
Some banks will develop their own electronic trading systems in-house, but this can be costly, especially when they need to connect to many exchanges, ECNs and brokers. There are a number of companies offering solutions in this area. Many types of algorithmic or automated trading activities can be described as high-frequency trading HFT , which is a specialized form of algorithmic trading characterized by high turnover and high order-to-trade ratios.
