Customer

The customer provides a foreign exchange ECN for retail brokers, institutions, banks, hedge funds and proprietary trading firms in the United States and Europe. The platform includes multiple integrated products and operates three separate and distinct matching engines located in New York, London and Tokyo. Each matching engine emits its own market data, trades and midpoint values.

Solution

Public and Internal Websites

Using PHP and Apache on the backend, HQSoftware developed a website that provides a wealth of real-time and historical market data through interactive Highcharts widgets. The latter display:

• Intraday volume (for the current day)
• Daily volume (for a particular day over the last four months)
• Book viewer with the top bids and asks for a particular currency pair
• Most actively traded pairs across the locations

The team implemented WebSockets to ensure real-time, uninterrupted streaming and display of large data sets (nearly 100 currency pairs per second) from the geographically distributed servers. This data is also stored in the MySQL database for historical insights.

In addition to that, the website serves as an informational and marketing tool, offering product and service descriptions, news, as well as the ability to register as a client and login. With the help of SSO (single sign-on), once logged in on the website, users can access the customer’s other products too, with no need to repeatedly type in their credentials.

HQSoftware also developed an internal portal integrated with the other solutions and enabling administrators to manage client profiles and roles within each client. Once assigned, roles are automatically activated across each solution in the ecosystem.

Online Trader’s Desk

HQSoftware has been enhancing and customizing the Caplin platform to provide users with outstanding online trading experiences, which mostly boils down to intuitive filtering and sorting of large tables of data. Specifically, the team:
Enabled smooth application performance in all browsers

• Improved the application logic so that users could get the needed information quicker and easier
• Increased customizability
• Reorganized the tabs and tab layouts for better UX
• Added the P&L monitoring tab, and more

Trading solution

The project team developed an application where financial institutions can manage and monitor their open positions with other institutions, as well as the open positions their brokerage clients have entered through the customer’s system. In addition to that, they can establish and manage trading limits for themselves and their brokerage clients.

Liquidity management and distribution solution

This Node.js tool enables financial institutions to configure liquidity for every client and every currency pair. Using the intuitive interface, they can easily add, group and lock both clients and pairs, which is then instantly shared across the entire ecosystem. The solution can be white-labeled and customized to an institution’s needs.

System monitoring tool

HQSoftware created a real-time Node.js application for the customer’s personnel to gain full visibility into the system, across all the products. The team took full advantage of Polymer Project to display all this data smoothly and prevent users from getting bogged down with unwanted columns. Administrators can customize the table to filter and better analyze the data, with the ability to export the insights in XLS.

Leveraging security

The team went the extra mile to ensure ultimate financial data and transaction security for every product by using 2FA, SSL encryption, HTTPS security protocols, SSO and other proven tools.
