About Global Financial institution

A multinational investment bank that operates and manages most of the financial assets and securities like equity, Hedge Fund, Futures, Bonds, etc. It provides services in mergers and acquisitions, equity and debt capital markets, lending, trading, risk management, research, and liquidity and payment management. It provides products in Global Markets that cover securities and derivative products in both the primary and secondary markets. It has a global technology team that creates and enhances the platform for diverse trading needs for e.g. Legacy trading platforms as well as STP (Straight Through Processing) based transaction system.

Challenges and Solutions by Knoldus:

1. Growing the business by extending an existing platform for different clients
Extending the existing platforms needs a careful eye and an attentive ear to listen to the additional client-specific business requirement and fabricate it into the existing platform such that the other business flow is intact with the changes while the new client can go live without hassle. The architecture and flow of the system must also be improved along the way.

Knoldus Role
One of the proudest pieces of work done by Knoldus in this engagement has been the work done to facilitate the onboarding of new clients on the system. This has directly added more business to the users of the system and has enabled them to enhance their plans to onboard new clients. The system offers faster processing of trades with minimal user interventions and lowered risks. The system saves a lot of effort and resources by eliminating human intervention.

2. Introducing new trade workflow to reduce the number of transactions in trading and manual work:
In the current system, the mistakes in the transactions were resulting in another duplicate transaction and a lot of manual efforts to mitigate the errors. These redundant transactions were replicated all over the system from the front office to back to the settlement. For example, a Trade Order was Placed with a wrong account has to be canceled and placed again in order to correct the trade details

Knoldus Role
According to the FIX protocol specification of Trade flows, there is an efficient way to reduce the number of transactions while correcting the mistakes, i.e. replacing the previous order with new details, hence instead of two instructions of Trade "Cancel" and "New" step, Only a single "Replace" Instruction is required. Knoldus team has added this above-mentioned functionality of the system by enhancing it to support the Fix replace flow according to the Fix guidelines. This directly increments the number of things a client can do and makes a good case for banks client's to use this system.

3. Making the system compliant with regulatory requirements (MiFID II):
This year, the banks operating in the European market had to enhance their systems to comply with the Mifid II regulations. The system was no exception and required a good chunk of work to be done. The work was to be done for:

  • Transaction Reporting
  • R&I

Knoldus Role
The Knoldus team was involved entirely in the work to be done for both the above mentioned regulatory obligation and was successfully able to make the system compliant to the regulation. It was a regulation with strict deadlines and complex piece of work. The understanding and analysis had to be exhaustive and correct to avoid any deviation from the regulation. The art of software engineering was used by all involved at its best and results were tremendously satisfying.

4. Migrating Application to Common Messaging Platform:
The financial institution uses a list of applications for different flows of Trading e.g. There is a front office to middle office Flow, There is a middle office to Trading Booking Flow and Trade Booking to Settlement Flow. To improve the instruction flow and keeping the message in sync with all application for better accessibility and traceability of Trade Instruction from Front office to the settlement, the application needed to be on a global messaging infrastructure.

Knoldus Role
Knoldus migrated the application on the Global messaging platform to meet the above requirement. The solution involved creating a different security infrastructure that was needed by the global messaging platform as well as thoroughly testing all existing business flows from EMEA to APAC for regression impact.

5. Improving the Security Infrastructure: Financial Institution is very sensitive to the application security and infrastructure involving it. Having access to even single trading information to an unauthorized entity may lead to scams. The financial institution audit and assess the security risks from time to time and create programs to improve the existing platform to avoid unforeseen security risks. There was an instance infrastructural problem that was creating the risk of having some application infrastructure related access to unauthorized entities within the organization. This problem was replicating with every application being built with existing infrastructure.

Knoldus Role
Knoldus is migrating the application development and deployment infrastructure so that the above-mentioned risks are completely removed and the system is compliant to the existing and proposed security policy.

Knoldus Involvement in SDLC Activities: Communication is very critical while working with a decentralized global team of developers and operations to understand and analyze the flow of business and modeling the same into the end product. The system we work upon has developers from other global teams. It is exciting for us to understand other work cultures too. What helped Knoldus was our understanding of Scrum and correctly following it which ensured we were not stepping on the work of other teams and maintaining our deliverables timely and also addressing risks/problems correctly.

Knoldus has been involved in the following umbrella activities:
1. Adhering to the knoldus way of agile working (KnolWay) to analyze and understand the critical business requirements from users and creating the backlog for the same. In addition to that, The team was also involved in prioritizing the valuable deliverables first out the backlog.
2. Communicating the technical and business risks with users ahead of development so that risks can be minimized.
3. Proposing the new architectural and design changes for the proposed solution to the global teams and discussing them to improve the overall system design.
4. Apart from the development work, Knoldus has been actively involved in end to end testing of the newly developed functionality and checking the regression impact.
5. Knoldus has also been involved in user acceptance testing (demo to users) of the product in the UAT environment and subsequently releasing the same on production after taking of the user's sign-off.

Business Benefits:

The contribution of Knoldus results in the following business benefits:
1. After On-boarding the different clients and catering to their diverse needs, the Financial institution observed the increased user base of their trading platform from various regions contributing to their core business benefits.
2. Having simplified the Trade flow for FIX Replace, an enormous amount of manual work reduced from the client end, hence increased the number of actual trades processing transactions. This also enabled the firm to attract a growing number of users to the platform.
3. Improved the efficiency of the end users by introducing the automation in monitoring and issue tracking systems (A centralized workbench for monitoring trade lifecycle).
4. Making the system meet regulatory requirements on time to avoid non-compliance issues (MiFID-II).

Technical Specifications:

It is a middleware software system that corroborates the trading lifecycle and strives to minimize any manual work between the front, middle and back office leading in delays. It is primarily responsible for validation, matching, and linking of the trades and triggering of the booking message to the downstream systems. It is also responsible for sending the confirmation of the trades back to the clients. Another functionality handled by the system is trade enrichment. It is responsible for augmenting the captured trade from the front office to make it suitable for operations at the back and middle office.

The two inputs of the system are
1. Orde
2. Fix Allocation Instructions

1) Orders: The system captures orders (trades) from front office systems. The orders are market specific belonging to either EMEA or APAC regions. Further, the orders are classified into two types based on the business channel - high touch and low touch.

2) Allocation Instructions: The system supports three types of Allocation Instructions - New, Cancel and Replace as per Fix specification guidelines.

The system supports two forms of trades -
1. Pre Allocated trade
2. Post Allocated trade

1) Pre-Allocated trade: In a pre-allocated trade, the order is entirely ready for validation, linking and booking and hence does not require the client to send any Allocation Instruction.
2) Post-Allocated trade: In a post-allocated trade, the client sends in the orders to the front office and then allocates the orders by sending in the Fix Allocation Instruction.
