Understanding Order Management Systems in India

11 min read

Order management systems (OMSs) have become an integral part of a trader’s workflow and have become increasingly more entrenched on trading desks.

Historically, order management systems have focused on automating internal communications, allowing traders to electronically collect orders and instructions from portfolio managers, aggregate orders into blocks, manage executions, collect fills and allocate to several different accounts. Today, however, OMSs are enhancing their functionality by providing advanced trading tools including analytics and reporting, access to multiple brokers and execution venues, algorithmic routing capabilities, and advanced execution functionality available through direct market access (DMA) platforms and execution management systems (EMSs).

The following article provides information on the many components of an order management system, trends in the industry and information to consider when purchasing an OMS.


With order management systems being the central integration of front, middle and back office functions, it is important to understand the components of an OMS and how their functionality can add value to your business model.

The primary functions of an order management system are portfolio management, trade analysis, reporting, trade execution, trade management, compliance tracking and FIX /API connectivity. Each component plays an important role.

Portfolio Management

Typically, portfolio managers use a portfolio modeling module to construct, analyze, rebalance and run “what if” scenarios. This simulation process shows the risk and liquidity effects of potential changes in the portfolio. Once a trading decision is made, the portfolio manager will authorize the trade and send it electronically to a trader.


The compliance module determines if trades meet compliance policies. Some additional benefits provided by a compliance module include post-execution monitoring, audit trails and compliance administration. With tough industry regulation, compliance tops the operational priority lists of many firms.


The trading module provides real-time, fully customizable trade blotters that communicate with portfolio managers, compliance, back office, brokers and a variety of execution venues.


The FIX/API module provides for real-time trade and an indication of interest communication between the trader, brokers, and execution venues. Financial Information eXchange (FIX) or native API is the industry standard protocol for the real-time exchange of transactions and information related to the securities markets.


The last step in the order management process includes the confirmation and allocation of executed trades. Allocations are communicated to brokers via the phone, fax, Native API, or a direct FIX link.


Order routing networks are used to relay trading information between the order management system, brokers, and execution venues. Order routing networks can be categorized into one of the following types:

Point-to-Point – Orders are sent over a network directly to each broker or execution venue.


                        Orders are sent directly to brokers without passing through a third-party vendor

                        Use of all FIX or API capabilities


                        Requires more IT involvement on the user’s side

                        The manager must monitor FIX/API connections with each broker

                        The manager must test with each broker

Service Bureau (Protocol Conversion) – Orders are sent to the order routing network vendor who converts the order to the proper message format for each broker or execution venue.


                        Simple and quick to use

                        The vendor handles all FIX/API testing

                        The vendor monitors the communication line

                        The vendor converts all messages for broker compatibility


                        FIX/API capabilities are limited by the vendor

                        A system error can stop all electronic trading

                        The service bureau “sees” your trading data

Some of the most common order-routing network vendors include Bloomberg, Reuters, ITG Net, NYFIX, SunGard, TNS, Thomson ATR, Linedata, and Charles River. ( Not In India).


Technological advances have made trading more efficient than ever. As order management systems continue to enhance their functionality, additional trading tools have become available.

Crossing Networks/Dark Pools ( Not valid for Indian Trading ).

While crossing networks have been around for many years, it wasn’t until recently that dark pools of liquidity have proliferated. It is estimated that there are nearly 40 dark pools available today including proprietary dark pools as well as those available to both the buy and sell-side.

Dark pools are electronic trading venues that do not publicly display quotes. Orders are matched anonymously, often at the midpoint price or through negotiation with a counter party, and are typically done with minimal market impact.

With the development of the numerous dark pools of liquidity, fragmentation has become a concern. To address this, many providers are linking directly with each other in addition to offering access to their liquidity through algorithms.

Because of their ability to impact the natural price discovery process of traditional markets, darks pools have drawn attention from regulators. A section of Regulation National Market System (Reg NMS) focuses specifically on dark pools and states that any trading venue accumulating more than 5% of US equity volume must provide open quotes to the broad market.

Algorithmic Trading

Algorithmic trading has become increasingly popular over the past several years. Algorithms enable traders to automate the execution of their orders by aligning them with specific trading strategies. Cost, market changes, fragmentation, declining liquidity, decimalization and the advancement of electronic trading technologies have all been drivers in the development of algorithmic trading.

Algorithms have evolved from time and volume based strategies to more adaptive strategies. Recent developments in algorithmic trading strategies include dark pool algorithms and portfolio algorithms that take into account an entire portfolio of securities.

Execution Management Systems

An execution management system (EMS) is a trading application that has the ability to manage orders across multiple trading destinations, in a wide range of asset classes. EMSs can be considered a next generation direct market access (DMA) platform.

Many EMSs offer advanced trading features including direct market access, algorithms and trading capabilities in global equities, options, futures and foreign exchange. EMSs are typically stronger in trading capabilities but lighter in many of the OMS functions. The EMS is more agile and can adapt more quickly than the OMS in today’s rapidly changing capital markets, and some firms may find their abilities to be more valuable and practical for their needs.



One of the biggest trends is the concept of a globally integrated OMS and EMS. Surging market data volume is creating a demand for trading platforms that not only can handle increased data volume, but will also eliminate the hassles of dealing with two separate trade management systems. While OMSs are integral for portfolio modeling, compliance and accounting, EMSs are great for active electronic trading across multiple asset classes and algorithmic strategies. With the buy-side’s need for both sets of functionality, order management systems have been developing EMS functionality while execution management systems have been adding OMS functionality, thus causing a blurring of the line between the two systems.

Several recent EMS/OMS integrations include Linedata LongView and REDI, EzeCastle and BNY Convergex, LatentZero and Fidessa EMS, and ITG and Macgregor.

Data Latency

Another trend on NSE India that is capturing the time and attention of OMS providers is the movement to reduce data latency. Latency is the time it takes for data to move electronically from one place to another. Data is passed through countless network switches, market participants, servers and applications.

There are several methods to reduce transaction times. Enhancing technological infrastructure, buying data caching solutions, installing hardware accelerators and co-locating servers are among the most popular ways to reduce latency. Co-locating consists of a broker housing their algorithms and servers in the same room, or as closely as possible, to the actual servers of the exchanges and electronic markets. This process can eliminate even the most imminent time lags in the fastest area wide networks.

Industry Regulation

SEBI need various new Regulations by which Indian markets can compete with International Exchanges. Need Various Improvements on Algo Trading Regulation Front. So main focus must be on Algo Trading & Investor protection.

Industry regulation such as the SEC’s Regulation National Market System (Reg NMS) has helped solidify the eminent role of electronic trading in the US equities market. The same can be said about Europe’s Markets in Financial Instruments Directive (MiFID).

Best execution is not just desired by traders and money manages, it is now a regulatory factor that must be accounted for by both buy- and sell-side firms. The new regulation is heavily focused on electronic markets and investor protection, which has in turn had a great effect on the amount of electronic trading data produced. Compliance and regulatory factors have and will continue to influence the production of electronic trading systems and the overall electronic trading market.


Purchasing an OMS, or replacing an OMS, is a time-consuming effort that requires the involvement of numerous people and departments. Therefore, it is important to consider several different factors when beginning the OMS search process.

Product Price

Order management systems are either purchased or leased. Some vendors only offer one option while other vendors offer both. Purchasing a system usually entails a higher initial outlay of costs with monthly maintenance fees costing between 20-25% of the system price. Leased systems incur higher monthly premiums but come with a lower initial cost. Installation and integration costs are not usually included in the price of the system. Be sure to inquire about these costs.

Implementation Process

Implementation of an OMS often takes 3-6 months to complete depending on the complexity of the installation and the vendor’s number of current or pending implementations. A good way to find out what the installation process involves is to contact other clients about their implementation experience.


Some order management systems are complex and require the investment manager to have a sophisticated IT department. Be sure to balance the sophistication of your IT staff with the sophistication required by the order management system. For a fee, many of these vendors are willing to take on many of the IT requirements. Depending on the size and needs of your firm, some smaller vendors may not be able to provide the appropriate level of support required. Be sure to check client references on their ability to get support after the sale.

Third-Party Interfaces and Data Sharing

Firms need to think about how they will interact with the markets. Will they use crossing networks, algorithms, ECNs, EMSs, or simply use FIX /APIto connect to traditional brokers?

For complete automation, a system must be integrated with a portfolio management system, execution venues, trust accounting system, risk management, and other systems that need trade data. Many of these connections have been built and are available for your use, but some connections must be developed. If a system does not currently have an interface, the vendor will offer to build one for a fee. Be aware that being a beta for a custom interface often involves a lot of time on the manager’s part.

Transaction Cost Analysis Integration

Transaction cost analysis (TCA) tools analyze a firm’s executions and compare them to specific benchmarks. The tools look at the executions by broker, by trader, and by other metrics to measure how the buy-side trader is performing. These analytics try to analyze market impact, compare trade execution to the portfolio manager’s instructions, and examine the execution in conjunction with various portfolio or firm benchmarks.

The end result of TCA should be a scorecard that helps traders, portfolio managers, and the firm better understand their strategies and the impact the strategies have on performance.
