Any software or facilities that are generated and transmitted automatically into the Exchange's trading system to match without the requirement for the manual inscription of orders when fulfilling certain given parameters without the need to manually insert orders
shall be included. SEBI has permitted Exchanges to provide the algorithmic
trading facility to members using various tools or strategies for decision
support.

Algorithm trading is a trading technique that enables transaction decision-makers to take advanced mathematical tools into financial markets. The requirement for intervention by a trader of human beings is reduced in this kind of system and decision-making
is therefore very quick. This allows the system to benefit much before a trader
can even detect the profit possibilities on the market. Because major
institutional investors share a huge number, they are the ones that use
algorithmic trading extensively. It is also common through words such as
anything trading, black-box trade, etc.

HFT is a subset of algorithmic trading that involves latency-sensitive commercial tactics and uses technology to connect and trade in the trading platform, including high-speed networks, routings, etc. High-frequency trading development and profitability are largely due to the
capacity to react to trade opportunities that can last only for a small
fraction of a second. Co-location supplied high-speed traders with the vehicle
to seize such trading possibilities.

Practice renting space for traders who think they can benefit from this proximity to the facilities housing their computer servers. Co-location promotes latency arbitration and pure speed trading between markets. A trader must be in the first line in the
price time orders of the exchanges if latency arbitration is to succeed. The
order that is first in line with an offer or offer for a low price wins the
competition. It's a zero-sum game. The size of the average deal has dropped
considerably from several thousand stocks to several hundred as a consequence
of these developments. Volumes of equity have doubled. Dramatically compressed
spreads quoted.

Among these, arbitrage is by far the most popular approach used by traders. This allows traders a large range of algorithms. If the opportunity to trade in arbitration is profitable and several traders try to take the same amount at a given cost in a few
milliseconds, the pre-programmed algo trading engine
will achieve it. But in several seconds, people traders can just respond. An
automated system so prefers at such moments to outperform traders by taking
risks.

Any algorithm must be approved by an exchange to avoid such problems. Risk management system criteria, such as the maximum traded value, trades per second, and total traded quantity, must all fall within predefined parameters. An automated algorithm may make any effective trading
approach even more profitable. Because of the fierce competition, most powerful
algorithms try to shave microseconds off their deals. Speed can be increased by
ensuring that every stage of the process is optimised, from when the trading
engine generates the signal to how long it takes for the deal to reach the
exchange. Latency is the term used in the algorithm trading market to describe
how fast something happens.
