Algorithmic trading is a system of trading whereby advanced mathematical tools and computer programs are used in facilitating trade and making decisions in the financial markets. Algorithmic trading is a method that helps in facilitating trade and solve trading problems using advanced mathematical tools. This system of trading uses automated trading instructions, predetermined mathematical models and human oversight to execute a trade in the financial market. In algorithmic trading, traders leverage powerful computers that have the capability to process complex mathematical formulas. The use of high-frequency trading techniques also helps traders to make multiple trades within seconds.

## When did Algorithmic Trading Begin?

Algorithmic trading was introduced in the 1970s, this was then highly computerized trading systems emerged in the American financial markets. The New York Stock Exchange also introduced a system in 1976 which enhanced the acceptance of electronic trader by traders. Algorithmic trading was popularized by Michael Lewis, an author who drew the attention of market traders and the public to high-frequency algorithmic trading. The combination of an algebraic equation and rules of algebra is an example of an algorithm. When algorithms are used as a system of trading, complex formals and mathematical models are combined to be trading decisions in the financial market. Algorithmic trading can be applied in different market situations such as order execution and arbitrage.

## Do it Yourself Algorithmic Trading

When algorithmic trading was introduced in America, companies defined the structure of electronic trading, in the sense that average investors do not have access to electronic trading or do not know how to go about the system. Michael Lewis, an author who polarized algorithmic trading to the public also argued that companies who use the algorithmic trading system gained an advantage over other traders and engage in trading that only benefitted them and are detrimental to average investors. In recent times, Do-it-yourself algorithmic trading has become popular, this enables average investors to facilitate the execution of trades in the financial markets using high-frequency computers. The innovation of high-speed computers and the high speed on the internet has made this type of algorithmic trading even more popular and widely accessible by average investors.
