Screen-Based Trading System

The Screen-Based Trading System represents a major structural transformation in the functioning of financial markets, particularly in the context of banking, finance, and the Indian economy. It refers to an electronic trading mechanism where the buying and selling of securities take place through computer terminals connected via a network, rather than through physical trading floors. This system has significantly enhanced efficiency, transparency, and accessibility in financial markets and has become the backbone of modern securities trading in India.
With the growth of capital markets and increased participation of investors, screen-based trading has played a crucial role in integrating technology with finance. Its adoption has strengthened market integrity, reduced transaction costs, and contributed to the orderly development of India’s financial system.

Concept and Meaning of Screen-Based Trading System

A Screen-Based Trading System is an electronic platform that facilitates the execution of buy and sell orders for securities through computers. Orders entered by market participants are matched automatically based on predefined rules such as price and time priority. The entire process, from order placement to execution, is conducted electronically, eliminating the need for face-to-face interaction.
In India, screen-based trading was introduced to replace the traditional open outcry system, which was prone to inefficiencies, lack of transparency, and operational risks. The electronic system ensures anonymity of traders, faster execution of trades, and real-time dissemination of market information.

Historical Background and Introduction in India

The introduction of screen-based trading in India marked a significant milestone in the modernisation of the securities market. The system was first implemented with the establishment of the National Stock Exchange of India in the early 1990s. Subsequently, the Bombay Stock Exchange also adopted electronic trading, leading to the complete transition from floor-based to screen-based trading.
This reform was part of broader financial sector reforms aimed at improving market efficiency, investor protection, and global competitiveness. The shift to electronic trading aligned Indian markets with international best practices and supported the rapid expansion of trading volumes.

Features of Screen-Based Trading System

The screen-based trading system is characterised by several key features that distinguish it from traditional trading mechanisms. It operates on an order-driven market structure, where orders are matched automatically by the trading system. The system provides real-time information on prices, volumes, and order status to all participants.
Another important feature is transparency. Since all orders and trades are recorded electronically, the possibility of manipulation or unfair practices is reduced. The system also ensures speed and accuracy, as trades are executed within seconds, minimising delays and human errors.

Working Mechanism of Screen-Based Trading

The functioning of a screen-based trading system involves a series of well-defined steps. Investors place buy or sell orders through brokers using electronic terminals. These orders are transmitted to the central trading system of the stock exchange, where they are matched automatically.
Once a trade is executed, confirmation is sent to the broker and the investor. The details of the transaction are then forwarded to clearing and settlement agencies, which ensure the transfer of securities and funds. This seamless integration of trading, clearing, and settlement enhances the efficiency and reliability of the financial market infrastructure.

Role in the Banking and Financial System

In the banking and financial system, the screen-based trading system plays a vital role in facilitating capital market transactions. Banks participate in these systems as brokers, custodians, clearing members, and investors. Through electronic trading, banks manage their investment portfolios, trade government securities, and support liquidity management.
The system also strengthens the link between banking and capital markets by enabling efficient mobilisation and allocation of financial resources. Faster and more transparent trading contributes to better price discovery, which is essential for informed investment decisions and financial stability.

Importance in Capital Markets

Screen-based trading has transformed the functioning of capital markets in India. It has increased market participation by enabling investors from different geographical locations to trade without physical presence at stock exchanges. This has led to greater market depth and liquidity.
The system has also facilitated the introduction of new financial instruments such as derivatives, exchange-traded funds, and electronic initial public offerings. By supporting innovation and scalability, screen-based trading has contributed to the expansion and sophistication of Indian capital markets.

Impact on the Indian Economy

The adoption of screen-based trading has had a positive impact on the Indian economy. Efficient and transparent capital markets enable better mobilisation of savings and allocation of capital to productive sectors. This supports industrial growth, infrastructure development, and employment generation.
By improving investor confidence and reducing transaction costs, electronic trading has encouraged greater participation of domestic and foreign investors. Increased capital inflows strengthen economic growth and enhance the resilience of the financial system.

Advantages of Screen-Based Trading System

The screen-based trading system offers several advantages in banking and finance. It ensures transparency and fairness by providing equal access to market information. Faster execution and reduced operational risks enhance market efficiency.
Other advantages include lower transaction costs, improved audit trails, and effective regulatory oversight. These benefits contribute to a stable and investor-friendly financial environment, which is essential for sustainable economic development.
