In the last few years, algorithmic trading has been the most disruptive innovation to the operation of financial markets. 

Based on its technological advantage, this kind of trading technique has become a hot issue for gaining an edge in the fast-paced environment of the financial market, where every second counts.

Algorithmic trading is where the artificial intelligence programs automatically go ahead and execute trades that are set according to predetermined rules and market conditions. 

It executes trades at high speed by using mathematical models and statistical analysis to find trading opportunities. 

This kind of approach has a number of benefits over manual trading, which involves speed, accuracy and efficiency.

The theory behind algorithms and mechanics of price action is the complicated branch of study, but it is crucial to be aware of how this technology functions. 

This comprehensive piece reveals how algorithmic theory works, and it is not limited to the mere surface level of price action but rather how this depths are affecting the current trading styles. 

Through getting a full understanding of this, the readers will consequently have the capability of making informed decisions when selecting their own trading strategy.

Understanding Algorithmic Trading

Algorithm trading, often referred to as algo or black box trading, is a trending trading approach involving the execution of trades and market analysis by well-aligned computer algorithms. 

The key distinction is the direction given by such an approach, namely, the lowering of the human participation in transaction-related decision-making technologies. 

As the trading robots draw on complicated mathematical algorithms to identify what are considered as the most timely and perfect entry and exit points in the market with an incredible accuracy and speed.

Algorithmic trading is a mechanism of trading that involves traders processing trades in the financial markets while implementing self-developed sophisticated mathematical tools. Strategies involve the employment of highly advanced quantitative tools in the financial markets with the aim of making trading decisions. 

The stricter rules which are built into the model enable it to assess the most ideal seconds when a trade needs to be placed and, at the same time, forestall any considerable deviation in the price of a stock. 

Generally, the large blocks of shares will be purchased by necessarily dividing the big lot into smaller individual lots and allowing the complex algorithms to decide when to proceed with the buy order for these cheaper lots. 

Therefore, in this set-up, the role of the market trader is played. Hence, the computer decision is made in a blink of an eye. It makes it possible for the system to take profitable positions on the market as soon as an opportunity appears before a real person`s eyes can even notice such changes. 

The single biggest use of algorithmic trading can be seen among the high-profile institutional investors who own a huge percentage of a firm's total shares. Most often, it is a technology-driven trading approach. This method is continuously getting more and more widespread in recent years.

The Theory of Price Action

Critical to all algorithmic trading is a core idea of price action which represents the cornerstone principle of market dynamics. This explains why the price of stocks is a complete representation of all available data, historical price patterns as well as investor attitude. 

Algorithmic trading employs that fundamental rule by designing complex numerical algorithms that continuously analyze market data in search of patterns and inconsistencies that will be used to make those trading decisions.

Key Components of Algorithmic Trading

1. Mathematical Models

The whole process of algorithmic trading depends on a number of mathematical models that individually analyze the market from an individual standpoint by the means of the available data. 

Such models comprise a broad toolbox from the application of statistical methods to the deployment of machine learning algorithms, neural networks, and evolutionary algorithms. 

Even though these models are empirically proven, permanent refining of them is still necessary in order to keep the traders ahead of the changing and volatile market.

2. Transaction Decision Making

One of the major purposes of algorithmic trading is to do the transactions in the most efficient way, also avoiding the negative impact of the markets. 

The algorithms use complicated order execution methods to get this standard realized including the time-weighted average price, (TWAP), volume-weighted average price, or VWAP, and implementation shortfall. 

The platformize large orders by dividing them into multiple smaller notes and then selecting them to go by in strategic manner that greatly reduces the chance of being exposed to severe market movements that will negatively affect the final outcome of the process.

3. Technology Integration

Algorithmic trading and up-to-date technology are necessarily interrelated. The most important aspects of trading are speed and efficiency. 

High-frequency trading (HFT), an aspect of algorithmic trading, displays exactly this nature of convenience by adopting the latest hardware and software solutions to execute trades much more rapidly than humans ever could. 

The technological evolution embraces many moving parts, from co-location services to the low latency trading platform and this makes algorithmic trading one of the most innovative areas in fintech .

Applications of Algorithmic Trading

1. Institutional Investors

Huge institutional investors, such as hedge funds, asset managers, and proprietary trading firms, are the key players of the machine adopting trading. 

By having large amounts of capital at their fingertips, these institutions utilize the algorithm to execute in all spectrum of asset classes that could be found in equity, bond, currency and commodity markets. Institutional investors try to take advantage of innovative systems by automating trading process and optimizing the execution strategies in order to achieve the highest return rates together with the lowest transaction costs.

2. Market Making

Automated trading becomes indisputably one of the most important factors in the equalization of prices on the trading floor, the foremost task of any market maker. 

Market makers offer bid and ask prices around the clock as a rule, which makes trading easier for market participants. Algorithmic trading allows makers of market the possibility of reviewing their quotes that can be made based on the most actual conditions of the market with the trimmest price-setting and quick order processing.

3. Arbitrage Opportunities 

Algorithmic trading is great at revealing and making a profit from arbitrage opportunities essentially because of the price differences appearing in different sub-markets or trading venues. 

If it comes to geographical arbitrage, statistical arbitrage or even latency arbitrage, algorithms are perfect in profiting from the discrepancy in the market price. 

Computerized traders who place trades at very fast speed and ideal timing can realize gains from these temporal trading and intraday profits while they are still intact.

Impact of Algorithmic Trading

Algorithmic trading has brought a deep transformation to the financial landscape, bringing a new dimension of efficiency and easy-reaching of the assets. 

Retail traders used to be passive participants. Now, with the help of sophisticated tools and technologies almost like the ones used by institutions-they participate like the professionals. 

In addition to all of these advantages, algorithmic trading has increased the debate on market integrity, pool of liquidity fragmentation, and systemic risk. In this context, the critics allege that the recklessness of a race for speed and automation might aggravate market volatility and heighten the possibility of extreme market swings.


Finally, the algorithms-based pricing theory represents a turnaround in the world of modern finance, where the manner of trade operations and strategies are redesigned. 

Along with the technology revolution, algorithms have been changing and getting more complex, so it is logical that the impact of algorithmic trading all over the world is going to be felt more and more. 

Consequently, when participants in the market become familiar with the nuances of automated trade and consider its power, they will have the knowledge to manage the difficulties that are part of the modern financial system.
